I am attempting to zip a website's home directory but the archive contains the entire path of folders before getting to the one to be zipped. The command zip -r compressed_data.zip /home/vivek/public_html results in compressed_data.zip containing home->vivek->public_html rather than simply public_html and its contents.
What switch can I add to the command to omit including all folders in the path?
How do I launch the default Web browser from within a script? In the below script, the browser opens when the script is successfully run as an executable shell script:
#!/bin/bash
cd $1
php -S 127.0.0.1:5000
for f in *.html; do cp -- "$f" "${f%.html}.php"; done
x-www-browser http://127.0.0.1:5000/index.php
However, in this longer version with Kdialog UI, everything executes correctly (the files are created and the server starts in the chosen directory) except for the launching of the browser
#!/bin/bash
`kdialog --yesno "HTML Files created, make PHP?"`
if [ $? = 1 ]; then
`kdialog --sorry "No PHP files created"`
exit 1
fi;
if [ $? = 0 ]; then
`kdialog --warningcontinuecancel "Select HTML directory"`
if [ $? = 0 ]; then
cd `kdialog --getexistingdirectory`
#exit 1
else
`kdialog --warningyesno "You didn't select a directory. \
<br>Yes to choose, No to cancel."`
if [ $? = 0 ]; then
cd `kdialog --getexistingdirectory`
exit 1
fi;
fi;
fi;
if [ $? = 0 ]; then
PORTNO=`kdialog --title "Port Number" --inputbox "Port: (Eg 7000)"`
fi;
if [ $? = 1 ]; then
`kdialog --warningyesno "You didn't enter a port. <br>Yes to coose, No to cancel."`
if [ $? = 0 ]; then
PORTNO=`kdialog --title "Port Number" --inputbox "Port: (Eg 7000)"`
fi;
fi;
if [ $? = 0 ]; then
COPYORNEW=`kdialog --radiolist "Copy HTML or make new files?:" 1 "Copy \
HTML files" off 2 "Rename HTML files" off`
else
exit 1
fi;
if [ "$COPYORNEW" = 1 ]; then
php -S 127.0.0.1:$PORTNO
for f in *.html; do cp -- "$f" "${f%.html}.php"; done
#x-www-browser http://127.0.0.1:$PORTNO
exit 1
elif [ "$COPYORNEW" = 2 ]; then
php -S 127.0.0.1:$PORTNO
for f in *.html; do mv -- "$f" "${f%.html}.php"; done
#x-www-browser http://127.0.0.1:$PORTNO
exit 1
fi;
URL="http://127.0.0.1:$PORTNO"; xdg-open $URL || sensible-browser $URL || x-www-browser $URL || gnome-open $URL
In both the short- and long-form versions, the command to open the browser is the last.
I have a one line script to create a file in a directory and open the file with Kwrite. I'd like the script to prompt for the file name to be created and to be opened by Kwrite. At present it doesn't even open the terminal but ideally it should. How do I achieve this with the following script?:
cat > file.php & kwrite file.php
My intention is to paste copied portions of one file to create a new file.
About a month ago MySql server 8 stopped working on my Ubuntu 20.10 machine. I don't know what caused the problem but I suspect this followed an update. Since then I've scoured the Web for solutions based on the error message, tried and failed with all.
Finally I decided to follow the suggestion to uninstall and reinstall MySql. When I used the command sudo apt purge mysql* I was prompted to yes/no to deleting graphics, office and other applications that I use. So I instead used sudo apt purge mysql-server-8.0, rebooted the computer and reinstalled.
How do I completely uninstall and reinstall MySql without removing packages listed as dependencies, while keeping my data intact? Here's the console out put from the installation:

I recently changed my ISP and discovered a few days ago that I can't access from other computers or gadgets connected to the same home network, a domain I'm self-hosting (linked via a DDNS provider) on a local machine. It doesn't matter whether I use the full url www.example.com or the the wired card's IP 192.168.0.xx or the wi-fi's 192.168.0.xy from within the network. I can get the site from the host machine using the FQDN www.example.com.
I'm running Apache with virtual hosts on Ubuntu 20.10 and have set in /etc/hosts 192.168.0.xx www.example.com and 192.168.0.xx example.com.
From Web searches I discovered that my ISP's Hitron CODA router does not support NAT loopback as opposed to the old router of the previous provider that caused no issues with access within or outside the network.
My search suggested that running a DNS server on the host machine could produce a solution and it seems that dnsmasq is a less cumbersome server to install and configure than Bind9.
How can I install and configure dnsmasq to achieve my goal of maintaining access from outside to the domain while adding the ability to reach it from any computer or gadget within the network?

Is what I am contemplating possible? I have not yet installed dnsmasq for fear of breaking anything.
Thanks.
I installed WordPress from the console of Ubuntu 20.10 on a local machine and after setting up a site and attempting to install some plugins, I saw a notice that some, including Jetpack, were not compatible with my version of WordPress. The installed version is 5.3.5 and the current version as of today is 5.5.2 (when my hosted sites auto-updated and sent email notices).
My news installation's dashboard says "You have the latest version of WordPress. Future security updates will be applied automatically. If you need to re-install version –, you can do so here:" The "Check for Updates" button returns a message that I have the latest version but we know that's not so and the check doesn't even get my version info but inserts a dash (–) instead.
How can I access a repository with the current WP version so that I can upgrade without having to download and install from the archive at wordpress.org? The apt installation uses an array of directories and offers the convenience of running more than one site from the single codebase.
Thanks.
Today I discovered that I could not save word processing files to my hard drive and files could only be opened in read-only mode. Then I discovered it was a systemwide problem affecting even an attempt to navigate in Firefox. I attempted to reboot the system, Ubuntu Studio 20.10, and ended up with scores of lines of an error message or system fault.
My Web search suggests I might be experiencing a dead or dying HDD. I burned an ISO to a DVD to attempt to use it to boot up and check the problem drive. The actions need root or sudo privileges.
How do I create a user with sudo privileges when booted from a Ubuntu Studio DVD? Should I use regular Ubuntu instead? Thanks.
I'm using OBS Studio and would like to have a virtual video output saved permanently so that it can be run when the application is launched.
This command creates the virtual output:
sudo modprobe v4l2loopback video_nr=10 card_label="OBS Video Source" exclusive_caps=1
But I must run the command in console on each boot. How can I make this permanent? The plugin that utilizes the output in OBS Studio is configured to auto start but /dev/video10 is not available after a reboot of the system.
$ modinfo v4l2loopback | grep -i parm
parm: debug:debugging level (higher values == more verbose) (int)
parm: max_buffers:how many buffers should be allocated (int)
parm: max_openers:how many users can open loopback device (int)
parm: devices:how many devices should be created (int)
parm: video_nr:video device numbers (-1=auto, 0=/dev/video0, etc.) (array of int)
parm: card_label:card labels for every device (array of charp)
parm: exclusive_caps:whether to announce OUTPUT/CAPTURE capabilities exclusively or not (array of bool)
parm: max_width:maximum frame width (int)
parm: max_height:maximum frame height (int)
I have a two part matter for clarification. I have an external hard disk drive with two partitions. Each time I shut down the machine and start I have to mount the partitions.
(1) How do I configure it so that the partitions are **automatically** mounted on each boot?
(2) How do I make the partitions accessible to be able to save directly to them from applications? At present I can't navigate to them from application menus or set file paths for example for a video capture location. However, I can open them via the File Manager to drag and drop or copy files.
I'm using Ubuntu 20.04.
Thanks.
I'm attempting to upgrade to 19.10 from the 18.04 LTS but have encountered some blockages. I followed the instruction to change the line in release-upgrades then on trying got a message in the console that "Upgrades to the development release are only available from the latest supported release."
I then used the upgrade-manager (Alt F2), followed the instructions and got upgraded to 19.04. However a second attempt with the result shown in this image, confirmed that there is a 19.10 upgrade but I have no luck installing it. Photo
Attempts via the terminal:
"mark@mark:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 19.04
Release: 19.04
Codename: disco
mark@mark:~$ sudo do-release-upgrade -d
[sudo] password for mark:
Checking for a new Ubuntu release
Upgrades to the development release are only
available from the latest supported release."
I'd appreciate any help in getting over this hump.
Thanks.
