Shell Style Guide
>Bash is the only shell scripting language permitted for executables.Whelp, wrong right off the bat.I'm gonna get down my my knees here and beg everyone reading: use POSIX shell. Do not write scripts with bash. Do not write scripts with zsh. Do not write scripts with fish. Use POSIX shell.sh has a really bad interactive mode (so does bash), so I'm not gonna give anyone a hard time for using another shell as their day-to-day interactive shell. But, for the love of god, write your scripts with POSIX sh.
