BASH — Paul Sutton

I have decided to republish these links as there are a few people on the Fediverse who work or are involved in InfoSec and CyberSecurity. These videos are a starting point as it is very useful to understand how to use the GNU/Linux command line along with related tools in general.

You may find the links on the BASH Basics post useful

I am reposting links to previous blog posts that looked at these topics:-

I can be contacted on Fediverse / mastodon, search for @zleap@qoto.org.

LibreOffice 7.4

Mon, 26 Dec 2022 07:30:00 +0000

LibreOffice 7.4

Just downloaded and installed LibreOffice 7.4.3. The following instructions and video should illustrate the process. I did make a few errors and corrected them during the video.

Download the latest .deb from LibreOffice website
Copy to a sensible location and switch to that location 2a. In Debian you can right click on the graphical file manager and **Open Terminal Here.
Extract the .tar.gz file **tar -xvf file.tar.gz
Switch to root using **su -i ** (unless you want the path error shown in the video
Navigate to where you extracted the .tar.gz file
type **dpkg -i *.deb

This SHOULD install everything, set up Libreoffice and place components on the menu system.

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

CyberSecurity part 3

CyberSecurity part 3

You should now be set up with an account, so go ahead and login via the home page

Once logged in you will see the above screen

So as mentioned, I will be sharing a series of 8 videos that cover different topics on using the command line shell (BASH).

Note: Not all the commands covered in this BASH series will work, partly as it seems some are not included in the vfsync system.

Note 2 Also worth saying that vfsync using the sh shell and not the bash shell. This is more of a workaround, to provide shell access.

Bash Basics Part 1 of 8 | Access and Navigation – Youtube 30 mins

If you are concerned about privacy, I have included the invidious link below too.

Commands

So some of the commands covered in this video include:- * cal – calendar * man – man pages * clear – clear screen * pwd – print / present working directory * ls – list storage * ls -a show hdd * files prefixed with a period . are hidden * ls -a -l (-l is long format, more information) * cd – change directory cd no argument – back to home * e,g cd Music * mkdir – make directory (mkdir junk) * absolute and relative paths * absolute – path from root of file system /home/user/junk * relative – path from where you are now e.g cd Music * pushd and popd – go back and forth between folders (see video for details ) so pushd /home/user/music/pop from /home/user switches to the pop directory, using popd goes back to where you were before e.g /home/user * touch filename * touch file2 file3 * touch file1 (existing file) will update the date / time stamps * rm filename – deletes a file * mv filename newfilename – * can also move a file : mv file1 /home/user/junk/files/ * rmdir – remove directory * rm -r – recursive

Shell -

$ = indicates your normal user is logged in
# = denotes root (admin)

Resize and rename multiple files

Sat, 06 Nov 2021 11:00:00 +0000

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
