I agree with everything he said, but I'm currently living in the simple, honest truth of God's own "bash" just like he describes and I'm loving it. Maybe someday I won't. Maybe someday will be soon. Maybe my bash scripts are horrible nightmare fuel. But they're also my children. I love them. Even the ugly ones.
I do indeed "have 800 lines of bash that reimplements job parallelism with wait and PID files, has its own retry logic built on a for loop and sleep, and parses its own output to determine success or failure." I do suspect the script is self-aware. This pleases me. I will bend to its desires. If there comes a time when it no longer desires to perform CI for me, I will respect its wishes.
Why not use python at that point? Sounds like the bus factor would be pretty big on this one
This the most logical solution. Python is what you (should) turn to when your Bash scripts start looking like real software. Whenever I see a (non-geriatric) developer with a giant bash script, my first assumption is that this is a junior dev who doesn't know better.
Bash that can do the same job regardless of ci tools is underrated. I likevthat setup too because if your tesm eber needs to run a job/deploy/ect they can with the same exact processes the ci employs.
