Display a cool clock on your terminal

This command displays a clock on your terminal which updates the time every second. Press Ctrl-C to exit. A couple of variants: A little bit bigger text: $ watch -t -n1 "date +%T|figlet -f big" You can try other figlet fonts, too. Big sideways characters: $ watch -n 1 -t '/usr/games/banner -w 30 $(date +%M:%S)' This requires a particular version of banner and a 40-line terminal or you can adjust the width ("30" here).

Create a tar archive using 7z compression

Using 7z to create archives is OK, but when you use tar, you preserve all file-specific information such as ownership, perms, etc. If that's important to you, this is a better way to do it.

Stop Flash from tracking everything you do.

Identify long lines in a file

This command displays a list of lines that are longer than 72 characters. I use this command to identify those lines in my scripts and cut them short the way I like it.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Add thousand separator with sed, in a file or within pipe

Does not necessarily require a file to process, it can be used in a pipe as well: $ cat filename | sed -e :a -e 's/$.*[0-9]$$[0-9]\{3\}$/\1,\2/;ta' I don't remember where I copy/pasted this from, I wish I credited the original author
