Check These Out

Print a list of all hardlinks in the working directory, recursively
libpurple likes to hardlink files repeatedly. To ignore libpurple, use sed: | sed '/\.\/\.purple/d'

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"

Join lines and separate with spaces
Read vmargs.txt, which is a text file that could either be DOS-style (\r\n) or UNIX-style (\n) line endings and join the lines with a space separator. Can this be shortened/made more elegant?

Boooted as EFI/UEFI or BIOS

Countdown Clock
Countdown clock - Counts down from $MIN minutes to zero. I let the date command do the maths. This version doesn't use seq.

Remove last line from files recursively
Used this command recently to remove the trailing ?> from all the files in a php project, which has having some unnecessary whitespace issues. Obviously, change *.php to whatever you'd like.

Delete all empty lines from a file with vim
If you need to delete lines that may contain space characters (such as tabs or spaces) as well as empty ones, try: $:v/\S/d Just an alternative.

Continuously show wifi signal strength on a mac

Add GPG key easy - oneliner
Replace KEY with GPG key. This command will load GPG key and add it to your system so you can use software from third party repos etc.

List known debian vulnerabilities on your system -- many of which may not yet be patched.
You can search for CVEs at https://security-tracker.debian.org/tracker/ or use --report to get full links. This can be added to cron, but unless you're going to do manual patches, you'd just be torturing yourself.
