Function: projectile--posix-shell

projectile--posix-shell is a byte-compiled function defined in projectile.el.

Signature

(projectile--posix-shell)

Documentation

Return the POSIX shell the asynchronous indexer should run under, or nil.

The async runner wraps the command in POSIX-sh syntax (the { ...; }
2>file grouping in projectile-files-via-ext-command-async), so it needs
a POSIX shell rather than the user's interactive shell-file-name, which may be csh/tcsh/fish (see #2042). On Unix that is always /bin/sh. On Windows there is no guaranteed one, so we look for sh on the executable search path (e.g. the sh.exe shipped with Git for Windows or MSYS) and return nil when none is found - the caller then falls back to the synchronous runner, which drives cmd.exe without any POSIX syntax
(see #2116).
