Add all unversioned files to svn

No need for grep, let awk do the match. This will not behave properly if the filenames contains whitespace, which is awk's default field separator.

List of commands you use most often

If you use HISTTIMEFORMAT environment e.g. timestamping typed commands, $(echo "1 2 $HISTTIMEFORMAT" | wc -w)

gives the number of columns that containing non-command parts per lines.

It should universify this command.

Makes you look busy

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim. Drop this in your .bash_aliases and make sure that file is initialized in your .bashrc.

Facebook Email Scraper

(Apparently it is too long so I put it in sample output, I hope that is OK.)

Run the long command (or put it in your .bashrc) in sample output then run:

fbemailscraper YourFBEmail Password

Voila! Your contacts' emails will appear.

Facebook seems to have gotten rid of the picture encoding of emails and replaced it with a text based version making it easy to scrape!

Needs curl to run and it was made pretty quickly so there might be bugs.
