Kill the process *group* containing a process named svscan (djb's daemontools)

Daemontools[1] won't always properly reap it's children. Sometimes when you need to kill the main svscan process, you want to also clean up all of it's children. The way to do that is to send a signal to the entire process group. It is a bit tricky [1] http://cr.yp.to/daemontools.html

kill -9 -$(ps x -o "%c %r" | awk '/svscan/{print $2}')

avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...

Deletes cpu time consuming plugin-containe triggered by firefox

Auto-kill auto-spawned process

Given a process name (kdiff3 in this example) that keeps auto-spawning/starting, auto-kill until it stops, assuming there is an upper limit (if not, reboot). This was beneficial after I clicked the DIFF button in a git GUI on a merge commit. 2000+ files were being opened one after the other in my diff program (kdiff3). Each time I closed one (or quit Kdiff3), the next file would be auto-opened in Kdiff3.

while [ ! -z $(ps -A | grep -m1 kdiff3 | awk '{print $1}') ]; do kill -9 $(ps -A | grep -m1 kdiff3 | awk '{print $1}'); sleep 1; done

find and kill a zombie process

You cannot kill zombies, as they are already dead. But if you have too many zombies then kill parent process or restart service. You can kill zombie process using PID obtained from the above command. For example kill zombie proces having PID 4104: # kill -9 4104 Please note that kill -9 does not guarantee to kill a zombie process.

Slow down IO heavy process

compare to alternative : - directly tests the -STOP of the process to continue or stop loop, - background operator should be set (or not) at the call of the function For extension i suggest a slowPID() based on kill like above and a slowCMD based on killall.

a simple bash one-liner to create php file and call php function

One command line web server on port 80 using nc (netcat)

Very simple web server listening on port 80 will serve index.html file or whatever file you like pointing your browser at http://your-IP-address/index.html for example. If your web server is down for maintenance and you'd like to inform your visitors about it, quickly and easily, you just have to put into the index.html file the right HTML code and you are done! Of course you need to be root to run the command using port 80.

Instead of writing a multiline if/then/else/fi construct you can do that by one line

instead of writing: if [[ "$1" == "$2" ]]; then echo "$1 is equal $2" else echo "$1 differs from $2" fi do write: [[ "$1" == "$2" ]] && echo "$1 is equal $2" || echo "$1 differs from $2"

sort list of email addresses by domain.tld

email random list can be created here: https://www.randomlists.com/email-addresses

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Just type any sub-string of the command you want to search(provided you have used it sometime in the same session). Keep on searching by repeatedly pressing ctrl+r. Press enter once you get the desired command string.
