The Bash Hackers Wiki
Bash was the first scripting language I ever got "good" with.(I put "good" in quotes because while I could get basically anything done, I promise that it was not good looking).However, I feel like it left me a bit brain damaged, I still think in terms of quotation quirks and "sub-shells" even in proper languages such as python or rust.It also left me a bit weird when thinking about concurrency, because I never consider IPC, I just think in terms of jobs+join so my code ends up performing as a series of bottlenecks as everything rejoins the main thread.That said; getting good with bash has helped my career a lot as a sysadmin; but maybe this is part of why sysadmins struggle with real programming.
