Top Forums Shell Programming and Scripting Nagios script to get total and free memory Post 302885449 by zaxxon on Sunday 26th of January 2014 11:04:36 AM

Put the calculation of the memory into a function too. Call it only when needed - currently you call it all the time, makes no sense. It will be executed no matter what happens in the case/esac-block.
Second thing is, if you iterate through arguments with $# -gt 0 it will always be the same. You miss the shift.
Third, have the exit 0 at the very end of the script since this is, if not aborted earlier, the good exit code you want to have.
