In the past we had tools like clipper, FoxPlus or the ancient dBaseIII+/dBaseIV to create multi input forms in which we were able to put things almost anywhere in the reduced available space (25 lines x 80 cols).

Source: https://psychocod3r.wordpress.com/2020/07/21/exploring-borland-dbase-iv-for-dos/

I have, in example, seen the old systems at AutoZone stores where you get a form drawn on the screen, and the user can navigate through the fields before running an action.

Another example is:

¿Is it there a similar tool for bash?

I am aware of the dialog command, which provides customizable single-column multi input forms, but what I expect is the ability to tell where in the screen the labels and textboxes are going to appear.

I have seen enough answers on how to mount USB Disks via command line but I would like to know if is it there a text tool for managing the USB Drives.

Scenery

I own a server in a remote place. The server one HDD for the Operating System and Data, and a USB Drive for Backups.

Sometimes I need to remotely (SSH) manage the USB Drive in order to mount/unmount as desired.

It would be useful if we find a text only USB Disk manager.

Thanks in advance.

Glossary

• "manage" = Mount and Unmount in a visual mode, without doing magic in order to guess which /dev/sdX drive is and without having to memorize and write every single command in order to mount and unmount.
• "Manage" = Mount and Unmount in a terminal as you do in your favorite file browser.

I am trying to write a bash script which, once the user run it, checks if another process is running and show it on screen.

Of course, the script is intended for a different purpose, like sending an email once the script ends satisfactorily, or using a different way to send a message to the user.

The main purpose of this script will be to detect zombie processes which kept running for a certain amount of time and inform to the user to take some actions.

I am trying to check if a php script is running in the command line, so I have tried using this for checking if the script is running:

detector.sh

#!/bin/bash
var=$(pgrep -fl my-php-program.php)
if [ -z "$var" ]
  echo "Not running"
else
  echo "Running!"
fi

The script works, and it shows the contents of the running processes, after which I do some other if...else...fi validations with the $var variable contents to do something.

Nevertheless, if I run the process constantly using:

while true; do bash detector.sh; sleep 1; done;

The script detects itself and sometimes shows some positive false responses.

I have -unsuccessful- tried this to solve it:

var=$(pgrep -fl my-php-program.php | grep -v php)

Is it there another way to get this problem solved?

Thanks in advance.

P.S.: I don't want to solve this problem in PHP. I would appreciate a lot your advice for bash based solutions only.

Please note: parts of this question comes from my opened thread on reddit.

Please also note: The expected solution should be related to AnyDesk and i3WM, no "NoMachine", VNC, TeamViewer or any other remote desktop solutions. Thanks for understanding.

The problem

I am an i3wm user and I'd like to use AnyDesk unattended login but I can't enable it without super user privileges via sudo.

I mean, if I run sudo anydesk it works and allow me to do the changes needed to allow the unattended login but once I close anydesk, it does not work for a normal user session.

When I run anydesk as a normal user, all the Security options are greyed out and I can't unlock it by clicking on the "Unlock Security Settings" link.

What have I tried

I have seen this question, Cannot access security panel from anydesk and while the provided answers may help a lot, I am facing a different issue.

Once I use this suggested solution:

echo mynewpassword | sudo anydesk --set-password

My terminal responds with:

Setting the password requires administrator privileges and an installed service.

I have also tried with the answers to this question: Anydesk on Ubuntu does not save Unattended Access Security Setting with similar results.

I have read there's something related to polkit or policykit, which I don't have on my i3WM system and that's why I can't run graphic super user requests a la gksudo.

Any help is appreciated.

My System: Ubuntu 18.04 LTS (Updated)

Window Manager/Desktop Environment: i3WM

The Logitech K600 TV Keyboard works flawlessly in my Laptop for the majority of the tasks, the features of this keyboard are awesome as it has 3 dedicated keys which I use for switching between the computer (using wireless dongle) and 2 Samsung Galaxy Tab devices (bluetooth connected).

The problem

The 3 dedicated keys I mentioned before, are the same keys used for F1, F2 and F3 which I should trigger by pressing a key combination with the Fn key.

Expected solution

I would like to switch the usage of the dedicated keys in order to make them trigger the default F1, F2 and F3 keys *whith no need to use the Fn in a combination.

Please consider

1. I am using i3WM, no desktop environment, no other window manager.
2. A BIOS based solution will only work for the physical keyboard on the laptop, not for the wireless keyboard.
3. I have requested Logitech's support via support ticket, and they guided me to this page: https://support.logi.com/hc/en-us/articles/360025297893 which provides a list of resources made for Windows or MacOS. There's no a Linux solution from the manufacturers.
4. This question: How can I make the function keys the default on a Logitech K760 Bluetooh keyboard? has an answer but it is for a different model, whose solution does not work on my model.

If you need further information from my system, don't hesitate to drop a message.

My system:

Laptop Dell inspiron 15 3000
RAM: 16 GB
SSD 480 GB Kingston
Intel Core i3 7th Generation
OS: Ubuntu 18.04.4 with Software and System Updates
Web Browser: Mozilla Firefox, Google Chrome, Palemoon. All latest.
Terminal emulator: Yakuake, gnome-terminal.
Other Terminal: TTY1
Internet service provider connection speed: 100 Mbps (asymmetric)
Full upgrade: march 23, 2020

The problem

Just recently noticed that my mkv videos stopped working just after a system upgrade. That's why I requested help here: Error on videos (.mkv) after software upgrade. And the problem was partially solved.

Nevertheless I didn't notice that some other video overlay functions stopped working, like the overlay video which is used by AnyDesk to create the remote control session. Please see this screenshot.

Edit

Just entered the Ubuntu default desktop environment, and I noticed some weird green color artifacts on the desktop, which won't render on the top of the windows, just on the desktop.

Can somebody please help me to revert or fix the problem the upgrade created?

If you need further information please let me know. I don't know where to start the investigation and what I would do is to reinstall everything. But I would prefer not to.

Thanks in advance.

As the question itself says: I would like to know if there is a way to create a script or direct command line to run midnight commander mc and request the program to open an ftp connection on -let's say- the right panel?

Something like:

mc --open-ftp [email protected]:password --right-panel

Or something like that.

I have seen this tutorial and it works indeed: Save Connection Settings in Midnight Commander, but this allow me to have a bookmark list of my sites, which I must invoke just after running midnight commander.

Any ideas?

I have seen this question: Slow download speed in terminal and this one Different download speeds in Ifstat and Chrome and they are old, referring a different version of my current OS and/or related to a different thing.

My system:

1. Laptop Dell inspiron 15 3000
2. RAM: 16 GB
3. SSD 480 GB Kingston
4. Intel Core i3 7th Generation
5. OS: Ubuntu 18.04 with Software and System Updates
6. Web Browser: Mozilla Firefox, Google Chrome, Palemoon. All latest.
7. Terminal emulator: Yakuake, gnome-terminal.
8. Other Terminal: TTY1
9. Internet service provider connection speed: 100 Mbps (asymmetric)

My connection is showing different speed when running speed tests from terminal emulator, TTY and compared to what the speedtest.net page is showing on a web browser.

Screenshots here:

Firefox results on speedtest.net

Results on Yakuake, using the speedtest command in a terminal. TTY results are the same.

As you can see, the web browser shows I have 94.07 Mbps upload but the terminal shows only 4 Mbit/s.

Additional Questions

1. The results I am receiving in the terminal are real or is the web browser the real speed on my computer?
2. Is the terminal "locked" on the Internet speed?
3. If the answer to the previous question is "Yes", how can I unlock it?
4. If the answer to question 2 is "No", how can I make sure the web browser shows the real Internet connection speed?
5. Is it there a difference between "Mbit/s" and "Mbps"?

I have noticed some low speed when downloading large files, but had no problem until today, when I noticed that big files are delaying a lot uploading. And after checking out my logs on one of my local computers, which automatically uploads large files to a web server, I can see it is taking a long time to upload the file.

If you need further information about my system or connection, please let me know.

fdisk seems to have a Text User Interface via Cfdisk.

But I would like to know if there are some other useful tools like this for, let's say: ffmpeg and maybe some other like mail clients, other than alpine and these not-so-easy to use for the common user.

I mean: something easier, something which looks like a program, made for using the program, not to code it from scratch and without the need to write complex commands to do the task.

In example: If I want to convert my png files to jpg in a folder I know I can run for i in *.png; do convert "$i" -[parameter1] -[parameter2] -[parameter3] -[and so on] converted-"$i".jpg; done;

What if there is a tool for text mode only which shows something like this?

------------------------------
Folder [ ~/Pictures/folder-to-convert/ ]

Source Format      [ PNG ]
Destination Format [ JPG ]

[X] Resize
--- Width  [ 1920 ] [ ] auto
--- Height [      ] [X] auto

[X] Change quality
--- Percentage [ 60 ]

          [ PROCESS ]
------------------------------

Maybe something like this has been made before, and for other tasks. Which I would like to find.

Edit

Here is an example of what I am looking for, but for other software, like ffmpeg and if there is a collection of Software like this, I'll appreciate your answers.

LazyGit

In example, Jesse Duffield has created lazygit

A simple terminal UI for git commands, written in Go with the gocui library. Source: https://github.com/jesseduffield/lazygit

Which, in my laptop looks like this:

And this animation, which is provided by Jesse Duffield git repository:

I know I can create my own piece of Software with python, php, or any other programming language. But I would like to find alternatives to some GUI's for the terminal only.

Any ideas are welcome.

My System

Parts of this question comes from my post on Facebook

Some days ago I was trying to identify this terminal text editor because of the plugins which are available on the left and right sidebars:

So far we have identified that the editor is vi and I have successfully installed nerdtree plugin as it shows in the left sidebar, it was suggested in the comments of my Facebook post. Now I am looking for a way to install the minimap on the right. Maybe it is a plugin or something.

Any ideas?

Screenshots were added from my own desktop. Please notice that I am a i3WM user and I am using Yakuake as my terminal emulator.

NOTE

I guess this is the minimap https://github.com/severin-lemaignan/vim-minimap but I can't find a way to install in Ubuntu.

Screenshots from my Desktop

Update

This is what happens when I press i after selecting the Plugin 'severin-lemaignan/vim-minimap' inside the Plugin Installer from whithin vim

I work with some projects which requires data to be exact lenght, let's say: 120 characters.

Some editors, like gedit provides such functionality which allows you to visually have a limit where to stop thus making easier to create some content.

Is it there a way I can use something like this in a terminal? I mean: I don't want a terminal editor with a nano like function to show a right margin line, what I wish is to show a permanent line over the terminal in order to be able to run commands such as nano filename or cat filename, or other commands/scripts which will drop text results in the terminal, and have the same experience.

I work mostly with drop down terminals like Guake or Yakuake, but another alternative is good as I always work on fullscreen i3wm Desktop Environments.

I am using an xmacrorec/xmacroplay (from the package xmacro) in order to Record / Play keystrokes and mouse movements in X displays.

I run:

xmacrorec > file.macro

Which results in a file named "file.macro" with the corresponding code which will be interpreted by xmacroplay in order to repeat every mouse move and/or keystrokes, a sample of the code is shown right here:

MotionNotify 6 97
KeyStrPress Super_L
KeyStrPress Return
KeyStrRelease Return
KeyStrRelease Super_L
KeyStrPress Alt_L
KeyStrPress d
KeyStrRelease Alt_L
KeyStrRelease d
KeyStrPress Control_L
KeyStrPress v
KeyStrRelease v
KeyStrRelease Control_L
KeyStrPress Return
KeyStrRelease Return
ButtonPress 1
ButtonRelease 1
KeyStrPress Tab
KeyStrRelease Tab
KeyStrPress Tab

KeyStrPress Shift_R

KeyStrPress a

KeyStrPress Tab
KeyStrRelease Tab
KeyStrPress Tab
KeyStrRelease Tab
KeyStrPress Tab
KeyStrRelease Tab
KeyStrPress Tab
KeyStrRelease Tab
KeyStrPress Return
KeyStrRelease Return

As you can see and perhaps already knew, I can use the next code in order to reproduce keystrokes:

KeyStrPress a
KeyStrRelease a

Which will result in an "a".

So let's say I would like to write an "á" (an a with accent). I will need a portion of code like this:

KeyStrPress dead_acute
KeyStrRelease dead_acute
KeyStrPress a
KeyStrRelease a

But I can also use the "String" command inside the code, in order to write a more complex single-line sentence, which will result in an easy to read/understand portion of code, something like:

String Está lista la electrónica?

As you can see, words with accents are Está and electrónica. But when I try to play that portion of code, the accent letters won't appear, resulting in an incomplete sentence like this:

Est lista la electrnica?

I have read that I need to use unicode in order to reproduce such accent words, but even when I already know the corresponding unicode symbols, I don't know how to implement on this.

I would appreciate a lot if anyone explains how to solve this and/or provide any alternatives which play fair with accented words.

Words with accents, special letters like ñ, Ñ and the majority of the special symbols like @ ½ ~ ¬ ° and some other won't work so far.

Thanks in advance.

I am working on a project in which I need mplayer to run several instances in order to create voice-over-music real-time mixing from two files. So, the music is constantly playing at 90% volume (represented as "M" in the next timeline) and at certain moments we lower the volume ("m") in order to place voice ("V") over the music, after which we'll return the music to 90% when the voice sample finishes.

TIMELINE (Minutes)

0===========1===========2===========3===========4===========...
_____________VVVVVVVV__________VVVVVVVVVVVVVV__________VVVVV...
MMMMMMMMMMMMMmmmmmmmmMMMMMMMMMMmmmmmmmmmmmmmmMMMMMMMMMMmmmmm...

Everything is working pretty fine so far. But, for some reason, many times the second mplayer instance finishes the voice-off playback but the process still remains active and won't ever end.

The answer provided right here: Kill all processes except the one running the script is not working for this case.

I have also tried the accepted answer on this question: https://unix.stackexchange.com/questions/50555/kill-many-instances-of-a-running-process-with-one-command but this will kill EVERY instance of mplayer and I need to keep the first one constantly playing music.

In this page http://www.oracleflash.com/20/How-to-kill-all-processes-with-one-command-in-Linux.html they reproduce a way to Kill all processes initiated by an application. Which is really useful for this case but this will also kill all the instances of mplayer.

Expected solution

I am saving the PID of the music player with:

mplayer -shuffle -playlist playlist.m3u </dev/null >/dev/null 2>&1 & echo $! > player.pid

With that PID number, I'd like to use the last given page's solution in order to kill all the processes EXCEPT the one saved in the player.pid file. So, placing cat player.pid in the middle of

kill -9 `ps -ef | grep oraxpo | grep -v grep | awk '{print $2}' 

may do the trick.

The problem is I don't know where to place it. Or if is it there a different/better way to do it.

Another idea is to kill the last processes one at once but stopping on the very first one.

Any ideas are appreciated.

Thanks in advance.

I am using this command to play music in the background (without GUI):

mplayer -shuffle -playlist /home/geppettvs/NAS/Musica/playlist.m3u </dev/null >/dev/null 2>&1 &

Which results in music being gathered from the Music folder in a NAS, which is played in the background.

The playlist itself is just a playlist file made with Rhythmbox or any other music player software with the ability to manage playlists.

So, mplayer starts with a random song after which it will continue uninterruptedly playing music.

What I need is to somehow query mplayer and ask it for the song name which is currently playing in order to place it somewhere, let's say: write it in a text file for later usage. (Just the filename without path)

Right now once mplayer starts playing music from the playlist, some efforts to query what is mplayer playing will result in "playlist.m3u" as the title name instead of the actual mp3 filename.

Alternatives

I am open for any alternatives, just as long as there is a better way of doing this without a GUI. Just let me know and I'll try it. Any ideas are welcomed.

I am yet on my legendary Lenovo T400 laptop which has the built in LCD display and a VGA connector which allow me to have an external monitor attached to my laptop and share different sceneries for what is about the display arrangement.

The graphics card as showin in lspci | grep "Graphics" shows the next in a terminal:

geppettvs@T400:~$ lspci | grep "Graphics"
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

For local/remote/ssh coding/testing purposes, I would like to have a terminal (text only mode) in the builtin LCD and a GUI in the external monitor.

I have tried going into a text only session and starting the X via startx i3 (I am using i3wm for my graphic user interface) and I have also tried going in the GUI session and entering the thext mode via AltF1~F7 after which I try to start the X session but it throws me back to a GUI only mode session.

Both attempts are resulting in the same scenery: delivering a one-instance GUI or TUI mode.

I already have Guake running, which allows me to hit a key combo in order to invoke guake over any monitor but what I do need is to run a real TTY terminal in a monitor while I have another instance (it can be a different instance) of a session in a different monitor.

Is it there a way to accomplish what I wish?

Thanks in advance.

First of all:

This is not a duplicated of Cronjobs made via cronjob not working which seems to be fixed by simply giving execution permissions to the script and/or adding the #!/bin/bash at the beginning of the script.

I have tried some advices published on the net, forums and other but I haven't yet succeeded.

The scenery:

I am experiencing some issues when attempting to run custom scripts located on /usr/bin via cronjob. In example: I am using Ubuntu 14.04.3 with the i3WM Tiling Window Manager, in which I am trying to run a custom script named wall which should change the wallpaper with feh via command line.

The wall script does run well when it is invoked via terminal or the i3wm menu bar, which indicates the script should run, but, it does not.

The script

When I find for the wall script via whereis wall, the terminal shows the next results:

wall: /usr/bin/wall /usr/bin/X11/wall /usr/share/man/man1/wall.1.gz

I am not sure why do I have a copy of the script both on the /usr/bin and the /usr/bin/X11 directories but both them do the same when I run it manually. Neither one or the other do anything when I put it on the crontab.

The script contents is as follows:

feh --bg-scale "`shuf -n1 -e ~/.i3/wall/*`"

This command is going to get a random image from the ~/.i3/wall folder and scale that image to desktop's size in order to be used as a background image.

The script file properties looks like this:

geppettvs@T400:~$ ls /usr/bin -l | grep wall
-rwxr-xr-x 1 root      root       2067448 oct 21  2013 fotowall
-rwxr-xr-x 1 root      root          6264 oct 27 09:21 kwalletd
-rwxr-sr-x 1 root      tty             45 ene 27 07:51 wall
-rwxr-xr-x 1 root      root          1747 abr 25  2014 wallpaper-changer

Of which I just notice the property differs just by the "tty" in the script, which I changed to root via chown with no difference at all.

The crontab

My user's crontab currently contains the next:

GNU nano 2.2.6 File: /tmp/crontab.Fb84OE/crontab                                                                            

# m h  dom mon dow   command
# * * * * * /home/geppettvs/wifirc.sh # JOB_ID_2
* * * * * /usr/bin/wall # JOB_ID_4

My root user crontab looks like this:

# m h  dom mon dow   command

@reboot sudo iwconfig wlan0 rate 54M
* * * * * wall

But, neither the user's crontab or the root one does anything with this script.

Let's have in mind that, this time, I am talking about a simple wallpaper changer script. But I have some other scripts that won't run when I put them in a crontab.

Additional attempts

I have already tried using the #!/bin/bash in the first line of the script, leaving or removing blank lines at the top/bottom of the script and/or the crontab file. And it seems not to have effect to make it work. The same goes for trying to use the absolute path or invoking the script simply by name (which works on a terminal, indeed).

The Log

The Log looks like this:

Which seems to be running the script but nothing is happening on each scripts run iteration.

The question

Is it there something wrong I am doing? Or something else I should try?

Any help is appreciated.

Update

As mentioned in a comment for j0h's advice, I have also tried using the absolute path to the image's folder.

The command now looks like

feh --bg-scale "`shuf -n1 -e /home/geppettvs/.i3/wall/*`" 

and it does work on a terminal but doesn't run via cron.

I am guessing the issue comes from the grave accent (`) which can be leading to an interruption in the cronjob's execution.

Nevertheless, I have tried changing the grave accent for another symbol, after which the command stops working everywhere. You can see terminal's output as shown:

geppettvs@T400:~$ feh --bg-scale "'shuf -n1 -e /home/geppettvs/.i3/wall/*'" 
feh WARNING: 'shuf -n1 -e /home/geppettvs/.i3/wall/*' does not exist - skipping
feh: No loadable images specified.
See 'man feh' for detailed usage information

Any help for improving this command is welcome. Thanks in advance.

I (now) own an HP Slate 2(b2a28ut) which it's a fancy piece of technological art. It does look like a tablet itself and it acts like an Android Tablet because of its Capacitive Touch Screen, but it is more like an all-in-one desktop computer, mini size of course.

I also own some accessories like the Mini Docking station which allows me to plug USB Devices, HDMI Screens and Audio Devices (Speakers, Amplifiers, HeadPhones, etc.), in such Dock I am plugging a mouse and keyboard in order to run certain tasks, like the OS's install.

So let's have in consideration that this is a Desktop Computer and not an Android Tablet, Phone, etc., anyway let's call it "the slate" for simplifying this reading.

I have installed 3 OS's on this device which are:

1. Windows 7 32 Bit (Factory Default)
2. Ubuntu 14.04.2 32 Bit
3. Android 4.4-RC2 (x86)

All these are working good enough to keep them and run some testing on the device's capabilities of which I feel happy Ubuntu is doing a great work on terminals and low resource consumption software. It does not work so fine for multimedia but I don't care about that for now.

I have even found a way to prescind from the physical keyboard by using onboard

Now, as the question's title reads, everything is fine when I have the slate on the Docking Station, and it runs smoothly after removing it from the Docking station, except when I need to reboot and choose a different operating system for boot without the Docking Station and it's mouse/keyboard plugged in.

I am presented with the GRUB loader with the default Operating System highlighted and a decreasing clock in seconds to choose the OS I wish to boot.

But I can't choose anything. The touch screen seems to work but I can't point anything to choose the right option to boot.

I have seen How do I select which OS to boot with no keyboard on a laptop? Can I adjust GRUB loader settings from the booted Ubuntu OS? but this refers to changing the default highlighted operating system for unattended boot, which I solved by using the grub-customizer as mentioned in the answers of such question.

My question is related to the ability to set up something like mouse compatibility, which will react to the touch screen pressing, or physical button's binding in order to just move the marker to the desired operating system and bind another button to work as the return key in order to accept the selection.

Another good scenery would be to bind the Volume+ and Volume- for moving the selection and, when hitting the Volume keys don't stop the clock which seems to stop when the user interacts with the GRUB options.

Any help is appreciated a lot.

Oh! Yes. I have to explain that I need this because of The Slate's size is very convenient for the outdoors work in minimal space conditions. I set up several things related to telecommunications which forces me to go up on high towers or work in small size conditions where a laptop is not a solution and when hanging upside down, the slate and companions (docking, keyboard, mouse) is too difficult.

The dual boot thing is needed because of Ubuntu is faster than anything when it is about setting up certain things which you can access via telnet or ssh, and in such conditions, saving time is a must! But... unfortunately the final tests should be done in a Windows environment.

Thank you for your help!

First of all: Thank you for taking the time to read this and provide some help. Any advice is appreciated.

I am using Nautilus-Actions to add a custom context menu's action to create a copy of a JPG image and reduce its quality (and the file size) while preserving the image's dimensions.

Let's say I have this picture with 2.3 MB (2 261 588 bytes) file size and:

After opening the file in GIMP 2.8 in order to just export a copy and use the JPG Export dialogue box to reduce the quality of the image to 30%:

I get these properties in the image copy (251.8 kB (251 797 bytes) file size):

I am using Nautilus Actions to batch process a lot of images to reproduce the same behaviour via context menu by selecting a bunch of files in Nautilus, right click on any of these selected files, and choose the proper Nautilus Actions action. The result is a file containing the image in the same dimensions as the original, with less quality of course and the file size is a bit greater (275.3 kB (275 265 bytes) file size) but that's not a major problem for me.

The problem is happening when I try to batch process several image files, which results in the first file name cloned into several file names containing a different image each one. With the properties I set in this set of commands:

Basically, each Nautilus Action is using these parameters:

Command: convert

• From (imagemagick)

Parameters: %F.jpg -quality 80%% %F-80q.jpg

• Which is interpreted as: convert path/to/file1.mid.jpg -quality=80% path/to/file1.mid-80q.jpg

Working directory: %d

So, the result is:

Here we can see each image processed in a different file but just the first file name is used to assign the new names to the copied files. I want a result like:

File1.jpg === File1-80q.jpg
File2.jpg === File2-80q.jpg
File3.jpg === File3-80q.jpg
File4.jpg === File4-80q.jpg

And so on...

I have used Phatch to do such tasks but what I want is to just right click on the selected files and process in a single action.

Is it there a better way to do this? or... Can I improve in some way what I am doing already?

Thank you very much for your support.

P.S. I have seen How can I batch convert images to b/w while preserving the folder structure and Is there a way to batch export SVGs to PNGs? but I am not trying to run this from a terminal but from a context menu. If I am omitting something in this exercise don't hesitate to let me know! I'll appreciate it a lot. Thank you!

Edit

After using muru's answer I find that solution partially does what I expect.

More specifically it solves the file names problem. Nevertheless, I also expected to get smaller file sizes by running the proper convert file.jpg -quality 30% command and it is dropping bigger file sizes as you can see:

Does anyone know if there's something else I should add to the parameters seen in muru's answer? I appreciate a lot your efforts to provide help on this issue.

Update

I am writing this just to let people know I have seen where the problem was with the compression. The file I was trying to compress was already fully compressed so (as mentioned in muru's answer):

The process was just adding overhead without gaining anything.

I am sorry if this is not the place where to ask and if so, I would appreciate any of the moderators move this question to the right place in order to get the proper answer.

I am the webmaster and IT consultant for several local media, radio and TV stations and newspapers at my Place in Mexico. Let's mention the TV Channel 9 (http://www.canal9tampico.com), Diario Debate (http://www.diariodebate.info), El Universo Tamaulipeco Noticias (http://eluniversotamaulipeco.com)

Some of them have invited me to write a coverage or editorial column about technology and I am very interested on writing about Ubuntu and Open Source software such as The GIMP, InkScape, LibreOffice, etc.

The coverage will -of course- include my personal achievements and experiences based on the day-to-day usage of these software, among other software and/or online services.

I would like to know if it is legal or at least I won't break any rules by to mention the brand names, use logos to illustrate or including screenshots, video tutorials or something in the writing.

I will appreciate a lot your feedback.

Thanks in advance.

On a MS Based system (Windows, any versions) You can use the attrib command in order to change the attributes on a specified file, directory or directory with recursively changing the files inside the directory also, the command may look like:

attrib FOLDERNAME -s -r -a -h /S /D

Which will remove any attributes to a specified FOLDERNAME including the files/folders inside of it.

When a Virus modifies these attributes to the files/folders in a removable device (USB/SD Memory/HDD) in order to hidden them from the user, I use my Ubuntu OS Based computer and plug the device in the appropriate slot and I can see all the files/folders and manually remove the undesired items on the device. But I am in need to run to a MS OS Based computer/laptop in order to change the attributes via command line (cmd) and this way, "bring back" the items visible to the rest of the people.

Ubuntu is having the ability to change the file properties via GUI or chmod, but I haven't found a way yet to remove the hidden (attrib -h) attribute in a file/folder.

Is it there a way to do this? No matters if is a GUI or Terminal
