I’m doing multiple raid monitoring in the same script and I want to have the script send alert/go red if EITHER variable comes back null.
I tried reading up and thought I had it, but what I tried ended up just never failing.
For testing, I have it grep fail and this SHOULD cause it to fail, but so far, I can’t get it to fail, it actually just always passes.
The Test Environment looks like this :
var="$(sudo /usr/StorMan/arcconf GETCONFIG 1 LD 0 | grep Optimal)" var1="$(sudo /usr/StorMan/arcconf GETCONFIG 1 LD 1 | grep fail)"
This works for 1 Variable
if [ -z "$var" ]
I have tried
if [ -z "$var" ] && [ -z "$var1" ] if [ -z "$var" && -z "$var1" ] if [[ -z "$var" && -z "$var1" ]]
But to no avail, I’m sure somebody would know what I’m doing wrong in a heartbeat, I appreciate the time taken to read this!
|| rather than
if [ -z "$var" ] || [ -z "$var1" ]
The bash manual explains it:
AND and OR lists are sequences of one or more pipelines separated by the control operators
||, respectively. AND and OR lists are executed with left associativity.
