Print the IPv4 address of a given interface

Find out current working directory of a process
This is an alternative to another command using two xargs. If it's a command you know there's only one of, you can just use: $ ls -l /proc/$(pgrep COMMAND)/cwd

Recall last argument of previous command
!$ recalls the last argument of the previous command. This is very useful when you have to operate several operations on the same file for example.

shuffle lines via bash
Using perl in a one-liner is a bit overkill to randomly sort some input. `sort` from coreutils should be enough.

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

Find files recursively that were updated in the last hour ignoring SVN files and folders.
Find files recursively that were updated in the last hour ignoring SVN files and folders. Incase you do a full svn up on accident.

OpenSSL one line CSR & Key generation

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

Colorize matching string without skipping others
this is useful to highlight only some code without losing other lines (eg. software, logs, scripts)
