How can I determine if a process is running or not and then have a bash script execute some stuff based on that condition?
For example:
if process abc is running, do this
if it is not running, do that.
A bash script to do something like that would look something like this:
#!/bin/bash
# Check if gedit is running
# -x flag only match processes whose name (or command line if -f is
# specified) exactly match the pattern.
if pgrep -x "gedit" > /dev/null
then
echo "Running"
else
echo "Stopped"
fi
This script is just checking to see if the program "gedit" is running.
Or you can only check if the program is not running like this:
if ! pgrep -x "gedit" > /dev/null
then
echo "Stopped"
fi
