Check These Out

archlinux: check which repository packages have updates available
Shows which packages from the official repositories (not aur) have updates available. For most accurate output, the mirrors and package lists should be up to date.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

pretend to be busy in office to enjoy a cup of coffee
This will turn it in an infinite loop and also shows random words from a file, so it won't be the same each time and also not just a number.

Find common groups between two users
Updated according to flatcap's suggestion, thanks!

Watch several log files in a single window
It works like a "tail -f" on several files. Use the number keys 0-9 to set a baseline in the numbered window. Pressing "b" let you scroll back in one of the windows.

Find out the last times your system was rebooted (for the duration of wtmp).

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

delete a line from your shell history
If you're a moron like me, sometimes your fingers get away from you and you, for example, enter your password when you're already authenticated to ssh-agent, sudo, etc., and your password ends up in shell history. Here's how to get it out.

list unique file extensions recursively for a path, include extension frequency stats
Get the longest match of file extension (Ex. For 'foo.tar.gz', you get '.tar.gz' instead of '.gz')
