Hi all, Can someone pls help me on how to make this bash script? I want to monitor a process, and then when the process (for some reason) dies, the script will start the process again.
One possible approach is to look at an offering from qmail's author, D. J. Bernstein http://cr.yp.to/djb.html. DBJ publishes a very useful set of tools known as daemontools http://cr.yp.to/daemontools.html. Supervise http://cr.yp.to/daemontools/supervise.html switches to the directory named s and starts ./run. It restarts ./run if ./run exits. It pauses for a second after starting ./run, so that it does not loop too quickly if ./run exits immediately.
Monit http://www.tildeslash.com/monit/ is a utility for managing and monitoring, processes, files, directories and devices on a UNIX system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations.
restartWrapper (comes with Radiator) is something that has never failed our operation in a decade, but I'm not sure what the license looks like.
