This script will check process if it is not running and will start the process if not running.

| proc_script.sh

#!/bin/bash
# check process
ps -ef | grep -v grep | grep 2200:localhost:22
# if not found - equals to 1, start it
if [ $? -eq 1 ]
then
ssh -f -N -R 2200:localhost:22 k2patel@71.245.248.138
echo "Process not running - Started"
else
echo “Process Running - do nothing”
fi

I made some changes as there is actually no need to equality check:

| proc_scriptjt.sh

#!/bin/bash
# check process
 
# if can parse the statement and watch the exit code
if [ "$(ps -ef | grep -v grep | grep 2200:localhost:22)" ]
then
ssh -f -N -R 2200:localhost:22 k2patel@71.245.248.138
echo "Process not running - Started"
else
echo “Process Running - do nothing”
fi

This is in python :)
