Linux command to check if a shell script is running or not

Question

What is the linux command to find if a process say aa.sh is running or not. ps command does not seem to work and it does not show the shell script names.

Please advi

Answer 1

Give an option to ps to display all the processes, an example is:

ps -A | grep "myshellscript.sh"

And as Basile Starynkevitch mentioned in the comment pgrep is another solution.

Answer 2

Check this

ps aux | grep "aa.sh"

Answer 3

pgrep -f aa.sh 

To do something with the id, you pipe it. Here I kill all its child tasks.

pgrep aa.sh | xargs pgrep -P ${} | xargs kill

If you want to execute a command if the process is running do this

pgrep aa.sh && echo Running
