Check These Out

Get a list of ssh servers on the local subnet
--open -sV is not needed if you are only looking for hosts with 22 open

Find files of two different extensions and copy them to a directory

Read random news on the internet

Multiplication table

convert single digit to double digits
Uses 'rename' to pad zeros in front of first existing number in each filename. The "--" is not required, but it will prevent errors on filenames which start with "-". You can change the "2d" to any number you want, equaling the total numeric output: aka, 4d = ????, 8d = ????????, etc. I setup a handful of handy functions to this effect (because I couldn't figure out how to insert a var for the value) in the form of 'padnum?', such as: padnum5 () { /usr/bin/rename 's/\d+/sprintf("%05d",$&)/e' -- $@ } Which would change a file "foo-1.txt" to "foo-00001.txt"

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"

show current directory
Opens a file or URL in the user's preferred application.

Display a random crass ascii art from www.asciiartfarts.com
Optionally, pipe the output into http://sed.sourceforge.net/grabbag/scripts/html2iso.sed Or: wget -qO - http://www.asciiartfarts.com/random.cgi | sed -n '//,//p' | sed -n '/

move contents of the current directory to the parent directory, then remove current directory.
I think this is less resource consuming than the previous examples
