There is a python program I am making, and I am planning to have it launch via a bash script. However the program acts badly when the computer tries to launch it twice. Since I really only need this program to launch once, how do I tell if the program is already running or not.
How can I make a bash script that determines if a program is already running
bash;python
If your bash script is called my_script.sh, then add this at the top:#!/bin/bashfor pid in $(pidof -x my_script.sh); do    if [ $pid != $$ ]; then        exit 1    fi donepython python_app.pyIt will list all the PIDs related to my_script.sh and verify if they are the same of the process we are currently running. If not, then exits the script.
