| - | ==== Process Check script for cron ==== | ||
| - | This script will check process if it is not running | ||
| - | and will start the process if not running. | ||
| - | |||
| - | ==== First ==== | ||
| - | |||
| - | <code bash | 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 [ $? -eq 1 ] | ||
| - | then | ||
| - | ssh -f -N -R 2200:localhost:22 k2patel@71.245.248.138 | ||
| - | echo "Process not running - Started" | ||
| - | else | ||
| - | echo “Process Running - do nothing” | ||
| - | fi | ||
| - | </code> | ||
| - | |||
| - | ==== Second ==== | ||
| - | |||
| - | I made some changes as there is actually no need to equality check: | ||
| - | |||
| - | |||
| - | <code bash | proc_scriptjt.sh> | ||
| - | #!/bin/bash | ||
| - | # check process | ||
| - | |||
| - | # if can parse the statement and watch the exit code | ||
| - | if [ "$(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 | ||
| - | </code> | ||
| - | |||
| - | ==== Third ==== | ||
| - | |||
| - | |||
| - | This is in python :) | ||
| - | |||
| - | <code python> | ||
