ps -xaw -o state,ppid | grep Z | grep -v PID | awk '{ print $2 }' | xargs kill -9

Functions: awk grep kill ps xargs

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.

mdmfs -s 256m md /mnt
echo `disklabel mfid1s4 | sed -n '$p' | awk '{print $2}'` / 1024 / 1024 | bc -l

kill -9 `ps xawo state=,pid=|sed -n 's/Z //p'`

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

kill -9 `ps -xaw -o state -o ppid | grep Z | grep -v PID | awk '{print $2}'`

Functions: awk grep kill

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 -9 `ps -xaw -o state -o pid | grep Z | grep -v PID | awk '{print $2}'`

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 -0Lauf - /dev/adXsYz | gzip > /path/to/adXsYz.dump.gz
2010-07-19 00:54:40
Functions: dump gzip

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 -
cd /usr/home && for i in *;do chsh -s bash $i;done

Functions: bash cd chsh

This command will set bash as the default shell for all users in a FreeBSD system.

stat -f '%Sp %p %N' * | rev | sed -E 's/^([^[:space:]]+)[[:space:]]([[:digit:]]{4})[^[:space:]]*[[:space:]]([^[:space:]]+)/\1 \2 \3/' | rev

User: vwal
Functions: rev sed stat

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.

ifconfig | grep "0xffffffff" | awk '{ print $2 }' | xargs -n 1 ifconfig em0 delete

User: vwal
Functions: awk grep ifconfig xargs

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