Shell script getting input from output

aspect_p · #1 (**permalink**) 03-10-2008

I have a program that can be run in terminal, when its run it either returns SSH OK or CRITICAL, how do i use the output in my script?

good
./check_sh myserver
SSH OK

bad
./check_sh myserver
CRITICAL

I want to store it in a variable btw, SSH OK will give the variable $SSH=1 and if its critical $SSH=0

Code:

#! /bin/bash

RESULT=$( /absolute/path/to/check_sh myserver )

case ${RESULT} in
   "SSH OK" ) SSH=1 ;;
   "CRITICAL" ) SSH=0 ;;
   * ) SSH=<some_other_value> ;;
esac

Also; convention would have "0" being a success, not a failure as you have it.

Cheers,
ZB
