proper way to detect shell exit code when errexit option set

Question

I prefer to write solid shell code, so the errexit & nounset is alway set.

The following code will stop at bad_command line

#!/bin/b         


        

Answer 1

Agree with comments, so if you can give up errexit then you can easily shorten your code to

 bad_command || do_err_handle
 good_command

I hope this helps.
