A simple shell script to reset CoreSimulator

simkill.sh

#!/bin/sh

pids=`ps axo pid,command | grep CoreSimulator | grep -v "grep CoreSimulator" | cut -c 1-5`

if [ "$1" = "go" ]; then 
	kill -9 $pids
elif [ "$1" = "echo" ]; then 
	echo $pids
else
	pid_param=`echo $pids | tr -s ' ' ','`
	ps -p $pid_param -o pid,command
fi

If I'm reading right, the cut -f 1 -d " " at the end of the first command omits results that start with a space, meaning the pids that are only 4 digits long. How come? I'm just not familiar enough with this to know why.

@hisaac Good catch. I've updated the script so it just uses column position 1 through 5. That catches the process ids with less than 5 digits.

In case they're not in your arsenal, check out pgrep/pkill.

Rather than the grep/grep -v you can use grep "[C]oreSimulator". The regexp won't match the parameter to grep.
