BASH Videos

I am trying to make some really simple screen cast videos, illustrating a few BASH commands. These are being published on my peertube account

They should also be federated to Mastodon.

To give an example, this video shows usage of the rename command



Use pastebin from command line

Use pastebin from command line

Quite often, when you have a problem where, in order to get help you need to paste the contents of a file,or command output so that it can be shared, for example on IRC (Chat) or a forum, this can be challenging to begin with.

As it is depreciated that you paste more than 2 lines in to IRC chat. The way round this is to use a service called pastebin. Debian [1] has it's own service for this [2]. There is a tool called pastebinit which is really helpful from the command line.

The first step is to switch to the root user. Sear for and install the package pastebinit as per below.


root@Desktop:/home/user# apt search pastebinit
Sorting... Done
Full Text Search... Done
pastebinit/stable 1.5.1-1 all
  command-line pastebin client


root@Desktop:/home/user# apt install pastebinit

The following packages were automatically installed and are no longer required:

Use 'apt autoremove' to remove them.
The following NEW packages will be installed:

After this operation, 342 kB of additional disk space will be used.

Selecting previously unselected package pastebinit.
(Reading database ... 190310 files and directories currently installed.)
Preparing to unpack .../pastebinit_1.5.1-1_all.deb ...
Unpacking pastebinit (1.5.1-1) ...
Setting up pastebinit (1.5.1-1) ...
Processing triggers for man-db (2.9.4-2) ...

Once complete switch back to normal user (usually type exit)

user@Desktop:~$ cat /etc/apt/sources.list > pastebinit
user@Desktop:~$ cat /etc/apt/sources.list | pastebinit

In this example I have used the cat command and piped the contents in to pastebinit, this has given me a url to paste in to chat, (or copy manually)

Open this in a browser and you and others can see the contents, and people can help you further.

paste bin it output

This is really useful too if you are stuck at the command prompt, without a graphical interface.

Resize and rename multiple files

As I was renaming and resizing some files anyway. I decided to make this short video of the process. I have added to Debian category as I am using Debian 11.

Commands used:-

gm -mogrify -resize 640x480 *.JPG AND rename 's/P1/codeclub/'

As usual your mileage may vary, you need to check man pages for specific arguments for your needs.

Happy to try and help further via Mastodon
