Check These Out

ssh autocomplete
Add to your bash profile to minimize carpal tunnel syndrome. Doesn't work with user@hostname but appending "-l user" works fine if needed. Works for ping as well.. complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ping

What is my ip?

Report all quota usage
Check disk quota for all user

Display disk partition sizes
Use lsbk (list block) and jq (to manipulate a JSON on the command line) to display partition information:

Generate a random password 30 characters long
Find random strings within /dev/urandom. Using grep filter to just Alphanumeric characters, and then print the first 30 and remove all the line feeds.

Remount root in read-write mode.
Saved my day, when my harddrive got stuck in read-only mode.

Restrict the bandwidth for the SCP command
the command is obvious, I know, but maybe not everyone knows that using the parameter "-l" you can limit the use of bandwidth command scp. In this example fetch all files from the directory zutaniddu and I copy them locally using only 10 Kbs

Remove newlines from output
Pipe any output to "grep ." and blank lines will not be printed.

Set RGB gamma of secondary monitor
This command first determines whether a second screen is connected. If this is the case, it sets the screen's RGB gamma via xrandr. Useful for cheap or slightly defective monitors with a tint. In this example a yellowing/champagne color deviation is compensated for by decreasing the red and the green portion of the image.

Set GIT_COMMITTER_DATE = GIT_AUTHOR_DATE for all the git commits
