If you use the terminal alot, you’re familiar with files like ‘.bashrc’, ‘.zshrc’, ‘.profile’, etc. I’m interested in understand where the shell options are configured outside of the standard ‘/etc’ and what many people refer to as dotfiles. I assume they must either be compiled in or packaged with your shell, and if you use one a set of completions.
A freshly installed CentOS system has ~25 lines of shell options pre-set, but my fedora 32 laptop has over 6000 lines. Each line is not a shell option, many are shell functions. Do you ever audit your shell options? Have shell options ever caused a problem for your servers? Are there good ‘hygiene’ practices for shell options on servers?
I realize these are pretty big questions, I’m happy to have a go at reading some C libraries if I need to, but hoping for something a bit easier to parse for me to dig into.
