Re: Mac terminal.app: starting emacs, possibly as sudo

[Marius Hofert <marius.hofert@math.ethz.ch>]

Dear Michael,

1) thanks a lot, that will definitely be useful in the future!

2) Concerning my last question: Is there any harm in "replacing" /usr/bin/emacs by /Applications/Emacs.app/Contents/MacOS/Emacs? This way one can easily use "sudo emacs" or "emacs -Q"... and start the GUI emacs with these features.

Cheers,

Marius
