Sane PATH variable in Emacs on Mac OS X

On Mac OS X the system PATH variable is not recognized by emacs. This means that one can not simply type

mysql

in the emacs shell to get into the database. The emacs shell complains about “binary not found”.

Indeed

echo $PATH

reveals that emacs just looks into /bin, /usr/bin, /sbin and /usr/sbin.

To set the $PATH variable inside emacs one can append the following lines to the .emacs file (found on github, hattip Alex Payne):

; sane path
(setq path "/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/mysql/bin")
(setenv "PATH" path)

Next time Emacs starts one can go to the shell and

mysql

presents the database prompt.
