Kill all Zombie processes one-liner

Did some research and found the previous command wrong, we don't kill a zombie but its parent. Just made some modifcation to khashmeshab's command.

Kill all Zombie processes if they accept it!

just a leaner, smaller version. Love the original idea!

Kill all Zombie processes (Guaranteed!)

It identifies the parents of the Zombie processes and kill them. So the new parent of orphan Zombies will be the Init process and he is already waiting for reaping them. Be careful! It may also kill your useful processes just because they are not taking care and waiting for their children (bad parents!).

Kill all Zombie processes if they accept it!

Tested on FreeBSD 8.1 and CSH. The scripts works correctly but the Zombies do not die! I hope it will run and function as expected in Linux and others.

Dump snapshot of UFS2 filesystem, then gzip it

Opens a snapshot of a live UFS2 filesystem, runs dump to generate a full filesystem backup which is run through gzip. The filesystem must support snapshots and have a .snap directory in the filesystem root.

To restore the backup, one can do

zcat /path/to/adXsYz.dump.gz | restore -rf -

Nicely display permissions in octal format with filename

Since the original command (#1873) didn't work on FreeBSD whose stat lacks the "-c" switch, I wrote an alternative that does. This command shows also the fourth digit of octal format permissions which yields the sticky bit information.

Delete all aliases for a network interface on a (Free)BSD system

The example command deletes all aliases for network interface 'em0' assuming that the aliases have netmask of 255.255.255.255 and the master IP has some other netmask (such as 255.255.255.0). See here -> http://my.galagzee.com/2009/07/22/deleting-all-network-interface-aliases/ for more on the rationale of this command.
