Matrix Screen HPUX
This is useful when you got a reserved IP address like 192.168.0.100 and want to find out what IP address is used to access the Internet. You have to know a server with 'efingerd -n' configured, like www.linuxbanks.cn as above.
Other method to find out this information are for example access www.tell-my-ip.com and grep the output. The finger method have the advantage that it is easy to deploy a service like www.tell-my-ip.com, as you only need to get efingerd installed.
You'll need "feh" to set the background from the commandline. Install with "apt-get install feh"

This one uses dictionary.com
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.
Change the name of the process and what is echoed to suit your needs. The brackets around the h in the grep statement cause grep to skip over "grep httpd", it is the equivalent of grep -v grep although more elegant.
Works recusivley in the specified dir or '.' if none given.
Repeatedly calls 'find' to find a newer file, when no newer files exist you have the newest.
In this case 'newest' means most recently modified. To find the most recently created change -newer to -cnewer.
If a directory name contains space xargs will do the wrong thing. Parallel https://savannah.nongnu.org/projects/parallel/ deals better with that.

Couldn't fit in 256
Created on Ubuntu 9.10 but nothing out of the ordinary, should work anywhere with a little tweaking. 5163 is the number of unique first names you get when combine the male and female first name files from. http://www.census.gov/genealogy/www/data/1990surnames/names_files.html
Get the line containing "inet addr:" and the line before that, get down to only the first line, and then get the first word on that line, which should be the interface.
A slightly shorter version. Also doesn't put a return character at the end of the password
Uses the dumb terminal option in gnuplot to plot a graph of frequencies. In this case, we are looking at a frequency analysis of words in all of the .c files.
This uses urandom to produce a random password. The random values are uuencoded to ensure only printable characters. This only works for a number of characters between 1 and 60.
Similar but using mediainfo instead of totem-something
note the xargs at the end
Some malicious program appends a iframe or script tag to you web pages on some server, use this command to clean them in batch.
Makes use of $RANDOM environment variable.
