Questions tagged [bash]
Bash is the `Bourne again Shell`, one of the more common Unix shell languages. This tag should be used for questions about editing bash scripts in Emacs, or writing bash scripts that invoke Emacs themselves. This tag doesn't necessarily apply to questions about running a shell in Emacs (which may use a language other than Bash), for which other tags are available.
