emacs command line parameter

emacs command line parameter

[Heiko Gerdau]

Hi,

I'm trying to start emacs using the command line options "-f" or "--eval" to 
run edirs (ediff) directly (or other functions) from a GNU linux command line 
(bash) with two directories (files) given. Something like: emacs --eval=edirs 
"MyDir1" "MyDir2" "cpp".
I never succeeded.

Is it possible to do that and what is the correct syntax?

Thanks for any hint.

Greetings
Heiko

I have had some problem with that with emacs-bidi, IIRC the = wasn't
supported and I am not sure about short versus long options. Try
removing the = and try both short and long options and see if one of
them works.

Thanks Micha for your answer. The "=" wasn't the problem but I finaly figured 
out a working syntax.

emacs --eval "(edirs \"MyDir1\" \"MyDir2\" \"cpp\")"

does the trick. It does also work with gnuclient and can be called via user 
menu of (for instance) the midnight commander to compare the directories 
panels currently shown or to compare a file present on both panels.
Great!
