Although I have found many many cases where one can use the split command to split a file into parts, I wasn't lucky enough to find a way to use split to massively split a group of files.

For example I have a folder and inside this folder are hundreds of files that start with the character "a" and end with ".txt". How can I get split with one line of code to split all of these files, say into parts with at most 20 lines of text? Something like:

split -l 20 a*.txt 

does not work because split gives an

extra operand "filename" error.

Thanks

I have a folder that contains hundreds of thousands of small .txt files of size 4kb. Some of them are totally empty while others are not. However, they all show the same size 4kb since this is the minimum block size configured. Is there a way to massively delete the empty ones but keep the non empty? Doing an

rsync --remove-sent-files -rv --min-size=4kb

removes everything.

Thank you

If I have in my fstab 10 shares/mountpoints, is it possible to run only a single mount command to mount them all at the same time just to avoid authenticating myself 10 times? I tried something like

sudo mount /mnt/share1, /mnt/share2, ... 

etc but with no luck. Authentication is the same (same username, same password) for all the shares I am trying to mount.

Thanks

Yes can't get the garbage out from my Ubuntu 14.04 LTS ( Ubuntu 12 had issues too! ). So (I login as a user who has sudo rights):

1st try right click on Trash > Empty Trash ... > Empty Trash and this is what I get, without seeing my Trash getting empty:

2nd try open Trash can > Empty --> same as above

3rd try open Trash can > try to delete a single file inside and I get the following:

4th try sudo nautilus > select Trash from Places -->

5th try posted a question to ask ubuntu --> ? ( Thanks! )

In the attached picture the annoying hover info covers my file. I can't either do a right click or see the name. Only maximizing the window solves the issue, but can't do that cause I need the space for the rest of the windows.

Long story short... anyone knows how to get rid of these annoying hover infos?

DEVELOPMENT

On my development server I have an Ubuntu user named user1. When user1 runs PyCharm (user1 must run a Django app) as sudo then the app at a later stage is required to create a folder folder1 to hold some personal files of user1. Now this folder when PyCharm is ran with sudo is created with owner:group = root:root.

1. Why I get this owner:group in the folder? Is it because I used sudo?

Now, when user1 runs PyCharm without sudo the same folder is created with owner:group = user1:user1

2. why I get this owner:group in the folder? Is it because I didn't used sudo and was logged in as user1?

3. Which process decides the group a created folder belongs to?

PRODUCTION

Again user1 has to run the Django app, but through the gunicorn service this time, which since it is a service can be ran only with sudo, so I always get the folder1 created as owner:group = root:root.

Now since my desired folder1 creation status needs to be user1:user1 and I can't run the gunicorn service without sudo what are the appropriate permission settings that would allow to have this? Bare in mind that the user needs to delete and re create this folder and all of its children under the same wanted permissions, so a simple manual chmod won't solve the problem.

4. How I should configure the production account to be able to have this behavior?

I am sorry if I confused you but I tried to describe in a very detailed manner the problem. Thank you very much.

In Ubuntu why can't I have a folder named "MyFile" and a document named "MyFile" at the same location? I get an item already used in this location error. Does Ubuntu / Linux treat folders and files as same objects (pointers to disk)?

Is there a way to make bigger the characters of xterm? Where can I access the properties of xterm and change their configurations?

Thank you !

Suddenly I realized that on my Ubuntu terminal ( 14 LTS ) every instance of character "w" does not appear correctly.

I've noticed that gedit behaves the same (shows a broken w), however "w" does not appear broken in xterm. Both terminal and gedit uses the Monospace 12 font.

Anyone knows what might be the cause, or where to look for this and how can it be fixed?
