`0 exit code, I get a 1` --> meaning you want to make a command fail when it passes. Remember `0` in shell's context is successful execution. You need to provide more details – Inian Apr 13 '18 at 09:57

@Inian Exactly. I want to make a command fail when it passes and pass when it fails. – ayushgp Apr 13 '18 at 09:58

2TL;DR: Use !. `! my_program`. – L3viathan Apr 13 '18 at 10:01
