Set file access control lists
The file myfile is owned by tom and has read and write permissions for tom. Group and other permissions are empty which make myfile readable and writable only by tom. setfacl enables user tom to give read permission to user john only. The command 'ls -l' shows a '+' sign telling us that file access control list has been setup for myfile.

Backup with versioning
Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

Show a 4-way scrollable process tree with full details.
If you want a visual representation of the parent/child relationships between processes, this is one easy way to do it. It's useful in debugging collections of shell scripts, because it provides something like a call traceback. When a shell script breaks, just remember "awwfux".

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

archlinux: shows list of files installed by a package
Shows the files which the package, for example gvim, installed on your system.

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