I have always been so/so on the linux command line. Does anyone have some onliners to share to get me started? I'd like to have some to look at, that i know are being used daily, so that i can research them some

Here's a good place to start: https://help.ubuntu.com/community/Be.../BashScripting and http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html.

Not being dismissive but the bash man page is very informative and written in a way that people can understand it.

Over here you asked why Linux sucks so baddly, and here, you're asking for help?

If Linux is hard you're doing it wrong.
