permissions on created files

permissions on created files

[Urs Thuermann]

When emacs creates a new file, it does so using mode 0666 modified by
the process umask, i.e. newly created files don't have the executable
bit set.  I have search the Emacs docs (with C-h i) and have also
tried C-h a to find a way to change this.  I'd like to change emacs'
behavior so that it uses 0777 instead 0666 when the file begins with
the two characters #!.  Is that possible?  I couldn't find anything
like that.

Modes like sh-mode generally do the Right Thing, if you use the
appropriate command (eg sh-set-shell) to set the interpreter.

Otherwise, try:

(and (fboundp 'executable-make-buffer-file-executable-if-script-p)
     (add-hook 'after-save-hook
               'executable-make-buffer-file-executable-if-script-p))

I think emacs just inherits the default umask from your environment.
However, thre are some variables which can control the setting of
executable bits on script files created within emacs. I'm not sure
what version of emacs you are running, but a quick apropos in emacs 22
brings up the function

executable-make-buffer-file-executable-if-script-p

which sounds promising as a starting point.
