Display a random man page

Build an awk array with all commands and then select a random one at the end.

This avoids spawning extra processes for counting with wc or generating random numbers.

Explicitly call /bin/ls to avoid interactions with aliases.

Display a random man page

Broaden your knowledge of the utilities available to you in no particular order whatsoever! Then use that knowledge to create more nifty one-liners that you can post here. =p

Takes a random number modulo the number of files in $dir, prints the filename corresponding to that number, and passes it as an argument to man.

print statistics about users' connect time

'ac' is included in the package 'acct', which is described as "The GNU Accounting utilities for process and login accounting". Other interesting flags are:

* print statistics for a specified user

ac -d username

* print statistics for all the users

ac -p

With my command, the output is also printed in a sexagesimal, more readable, style.
