sh-set-shell
sh-set-shell is an interactive compiled Lisp function in `sh-script.el
'.
(sh-set-shell SHELL &optional NO-QUERY-FLAG INSERT-FLAG)
Set this buffer's shell to SHELL (a string).
When used interactively, insert the proper starting #!-line,
and make the visited file executable via `executable-set-magic',
perhaps querying depending on the value of `executable-query'.
When this function is called noninteractively, INSERT-FLAG (the third
argument) controls whether to insert a #!-line and think about making
the visited file executable, and NO-QUERY-FLAG (the second argument)
controls whether to query about making the visited file executable.
Calls the value of `sh-set-shell-hook' if set.
