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. Show Sample Output

No output. But if you want to see the PIDs of your Zombies just use this piece:
ps -xaw -o state -o pid | grep Z | grep -v PID | awk '{print $2}'
```

kill all process that belongs to you

Kills all process that belongs to the user that runs it - excluding bash, sshd (so putty/ssh session will be spared). The bit that says grep -vE "..." can be extended to include ps line patterns that you want to spare. If no process can be found on the hitlist, it will print # NOTHING TO KILL. Otherwise, it will print # KILL EM ALL, with the cull list.
This is sample output - yours may be different.

ps -u $USER -lf | grep -vE "\-bash|sshd|ps|grep|PPID" > .tmpkill; if (( $(cat .tmpkill | wc -l) > 0 )); then echo "# KILL EM ALL"; cat .tmpkill; cat .tmpkill | awk '{print $4}' | xargs kill -9; else echo "# NOTHING TO KILL"; fi; cat .tmpkill; rm .tmpkill;

Terminate a find after the first match is found.

If you know that you want only the first match from a 'find' command, this will terminate the find as soon as a match is found. Recent versions of GNU find have the -quit parameter, which does the same thing as this, so this is only useful if you are stuck with an older version of find. or need to write a backward portable script. I can't take credit for this - I saw it on a chat room where I work and thought it was useful, so am sharing it here both for others, and in case I want to remember it in the future.

kill all running instances of wine and programs runned by it (exe)

The other 2 commands that are listed will also kill the egrep process and any libexec processes because the .exe isn't escaped so it is really using . meaning anything containing exe. The command i posted escapes the (dot) in .exe and then filters the actual egrep process so that it doesn't get killed before the other processes being killed. Also added the -9 switch for kill to send sigterm to the processes, in case people are wondering why processes aren't getting killed after running just kill . This should work better for people :)

mtr, better than traceroute and ping combined

mtr combines the functionality of the traceroute and ping programs in a single network diagnostic tool. As mtr starts, it investigates the network connection between the host mtr runs on and HOSTNAME. by sending packets with purposly low TTLs. It continues to send packets with low TTL, noting the response time of the intervening routers. This allows mtr to print the response percentage and response times of the internet route to HOSTNAME. A sudden increase in packetloss or response time is often an indication of a bad (or simply over‐loaded) link.
