Why are you running the script in the first place, if you want to later find it's pid and kill it? This doesn't appear to be an efficient way of achieving your task. What exactly do you want to achieve?

-o pid is a format specifier for the ps command that prints only the PID's of the processes specfied by the -c switch (in this case "myscript.sh"). But this will print the default column header name "PID" and then list all the pid's below this header. To have a different header name, you could simply say -o pid="MyScriptPIDs" .

Here, we are not supplying any header name in -o pid= , which means no header will be printed and so that you could use the output in kill command.
