Better git diff, word delimited and colorized
I've been using colordiff for years. wdiff is the new fav, except its colors. Word delimited diffs are more interleaved, easing the chore of associating big blocks of changes.

Change the homepage of Firefox
Pros: Works in all Windows computers, most updated and compatible command. Cons: 3 liner Replace fcisolutions.com with your site name.

Find directories under home directory with 777 permissions, change to 755, and list them on console

Don't save commands in bash history (only for current session)
Only from a remote machine: Only access to the server will be logged, but not the command. The same way, you can run any command without loggin it to history. ssh user@localhost will be registered in the history as well, and it's not usable.

Show interface/ip using awk
Interfaces like lo can be omitted from the beginning, there are probably better ways of doing this, i'm a noob at awk.

Check if a string is into a variable
Returns true (0) if the string is into $var, or false (1) if not.
