Can change language and speed, see espeak man page for options. (Install espeak in your linux distro via yum or apt-get)

For insomniacs you may need to enclose in a while true; do ...; done loop ;)

Echo the local IP addresses of the machines on your local network

If you need to ssh into a computer on the local network but you're unsure of the ip to use, then ping them and see if you get a response. If you do, print out the address you got it from. Adjust the range to suit your network.

Cleanup firefox's database.

Sqlite database keeps collecting cruft as time passes, which can be cleaned by the 'vacuum;' command. This command cleans up the cruft in all sqlite files relating to the user you have logged in as. This command has to be run when firefox is not running, or it will exit displaying the pid of the firefox running.

Emulate sleep in DOS/BAT

Enable 'sleep' function in Windows environment where this does not exist, although not exact in time. (there is a delay for each ping) This is a simple way to separate commands with a time-period.
