Display a random man page

Great idea camocrazed. Another twist would be to display a different man page based on the day of the year. The following will continuously cycle through all man pages:

man $(ls /bin | sed -n $(($(date +%j) % $(ls /bin | wc -l)))p)

command line fu roulette

retrieves the html from a random command line fu page, then finds commands on the page and prints them

alternatively, pipe to bash (add "| bash" to the end) to execute the command (very risky)

edit: had to adjust to properly display the portion that replaces HTML characters (e.g. " -> ")

If X is 5, it will about a number between 1 and 5 inclusive.

This works in bash and zsh.

If you want between 0 and 4, remove the +1.
