Remove old kernel packages

Find out when your billion-second anniversary is (was). (on OS X)

This is the same command as this one, but for OS X. http://www.commandlinefu.com/commands/view/3053/find-out-when-your-billion-second-anniversary-is-was.

Search some text from all files inside a directory

Get all files of particular type (say, PDF) listed on some wegpage (say, example.com)

See man wget if you want linked files and not only those hosted on the website.

Real full backup copy of /etc folder

Yes, rsync(1) supports local directories. And, should anything change, it's trivial to run the command again, and grab only the changes, instead of the full directory.

Press ctrl+r in a bash shell and type a few letters of a previous command

In the sample output, I pressed ctrl+r and typed the letters las. I can't imagine how much typing this has saved me.

Find brute force attempts on SSHd

Searches the /var/log/secure log file for Failed and/or invalid user log in attempts.

Show IP Address in prompt --> PS1 var

when working with many machines in a computer lab need to know the IP addr is very large, this is a simplistic solution to make things easier
