Randomize lines in a file
shuf is in the coreutils package

Use lynx to run repeating website actions
This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies). For creating your keystroke file, use: $ lynx -cmd_log yourfile

intersection between two files

Remove color codes (special characters) with sed

ShadyURL via CLI

split a multi-page PDF into separate files
Have to do this once per output file, because if device is 'pdfwrite', even if 'gs' sees '%d' in the OutputFile it still only creates one single output file. Embed it into a simple shell script if you want to split a document out into one file for every page.

Scan your LAN for unauthorized IPs
populate the auth.hosts file with a list of IP addresses that are authorized to be in use and when you run this command it will return the addresses that are pingable and not in the authorized list. Can be combined with the "Command line Twitter" command to tweet unauthorized access.

Paste the contents of OS X clipboard into a new text file

Get the version of sshd on a remote system
I used this to confirm an upgrade to an SSH daemon was successful

Get the ip registered to a domain on OpenWRT
I use this in a script on my openwrt router to check if my DynDNS needs to be updated, saves your account from being banned for blank updates.
