Fork Bomb for Windows
Quick and dirty forkbomb for all flavors of windows Do not use in production. Replace start with a command of your choice, this will just open a new command prompt and is pretty tricky to stop once started

check open ports without netstat or lsof

Check a server is up. If it isn't mail me.
For some reason the 2&>1 does not work for me, but the shorter stdout/stderr redirection >& works perfectly (Ubuntu 10.04).

Mount a disk image (dmg) file in Mac OSX
To unmount, replace "attach" with "eject"

Extract a bash function
I often need to extract a function from a bash script and this command will do it.

copy root to new device
Clone a root partition. The reason for double-mounting the root device is to avoid any filesystem overlay issues. This is particularly important for /dev. Also, note the importance of the trailing slashes on the paths when using rsync (search the man page for "slash" for more details). rsync and bash add several subtle nuances to path handling; using trailing slashes will effectively mean "clone this directory", even when run multiple times. For example: run once to get an initial copy, and then run again in single user mode just before rebooting into the new disk. Using file globs (which miss dot-files) or leaving off the trailing slash with rsync (which will create /mnt/target/root) are traps that are easy to fall into.

spawn shell listener service with nc

Gathering all MAC's in your local network
replace eth0 with your ethernet or wireless network interface.

Make a statistic about the lines of code
use find to grep all .c files from the target directory, cat them into one stream, then piped to wc to count the lines
