The first three variables point to system commands and utilities, and you may or may not need to change these values for your system.

This will keep your constituents happy and will enable you to make it home in time for dinner. IMPORTANT: BEFORE you deploy a script (or any new program, patch, application, database, upgrade, etc for that matter) in a production environment, always test in a non-production environment (i.e., development or QA) to ensure the script behaves as expected. The first part we will look at is the script itself, stepping through it line by line.

ProcMonUX consists of two parts: (1) the shell script that handles the Linux process monitoring, and (2) the automated running of the monitoring script. Although it uses the BASH shell and runs on Linux, it also works with UNIX and has been tested using the Korn shell. This process monitoring script can be used to monitor just one process, or multiple processes.

ProcMonUX is a simple shell script that will monitor Linux process availability, send you an email when a process is not running, and automatically restart the process for you.

If you do not have the time or resources to learn, install and configure a more complex Linux process monitoring tool, this simple (and free) shell script may be the right option for you.
