So I have a script that monitors my drives (/dev/sda and /dev/sdb) using smartctl (smartmontools). I'm by no means an expert in scripting, so this was my attempt at creating a way to email me if one of the values in smartctl output goes above a set threshold.
My question is, I'm trying to edit the "Subject" line of the email that it sends, so that I can tell which 'test' is failing. Is it temperature_celsius, etc? Is there a way to name each one and then use a variable like $failedtest in the subject line?
I'm at a loss for how to write this..

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Any cleanup/shorter command suggestions are always welcome too, this was just the best I could come up with.
