Check These Out

extract email addresses from some file (or any other pattern)

Generate SSH public key from the private key

Copy data using gtar

It copies the entire current working directory to the destination directory with compression enabled.

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"

Check if x86 Solaris based system is 32bit or 64bit

Display a Lissajous curve in text

Use Ruby's standard Curses module to display a Lissajous curve in the console. Replace the "0.2" with different numbers for different curves.

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"
