Manual - Watch It!

1. Copy the script to the same directory, where the program is located.
2. Open the script with your favourite editor like pico, nano or vi
   • path = Enter the path to the program you want to watch (e.g. /home/user/dir/ )
   • pid = Name of the .pid-file of that program
   • file = File to run your program
   • cmd = Possible arguments you need to start your program (e.g. |start ), if you don't need it, leave it blank
   • process = Name of the process of your program (use "ps -aux" to find out the process name. If the name is very long, you could cut it at the first space.)
3. Set the scripts CHMOD to 755
4. Define a cronjob:
   • Enter crontab -e and push return
   • Now you're at the "vi"-Editor and must enter, how often which action should be active
   • Example:
     
     */1 * * * * /home/user/dir/app.watch > /dev/null 2>&1
     
     Explanation:
     
     every minute in every hour in every week in every month in every year run app.watch and ignore all messages (Unix/Linux is sending system mails, which are not needed for the script)
     
     If you change the 1 to a 2, the script will run every 2 minutes and check, if your program is still running.
