Hello.  I would like to use emacs as I would use say diff or sdiff.

Is there a way to start emacs in ediff mode and pass along with it
through the command line, the two files I want to ediff?  If the
command line is unwieldy, I can always wrap it up in a script.
emacs --eval '(ediff-files "file_1" "file_2")'
It is a bit more difficult on Windows:

This works for me on Windows:

   emacs --eval "(ediff-files \"file_1\" \"file_2\")"

@rem Put this file (ediff.cmd) in your PATH.

@rem -----------------------------
@rem Starts Emacs ediff (through gnuserv) from command line.
@rem Takes the two file to compare as parameters.
@set f1=%1
@set f2=%2
@set f1=%f1:\=/%
@set f2=%f2:\=/%
@set emacs_cd=%CD:\=/%
@set emacs_client="c:\emacs\p\070403\emacs\bin\emacsclient.exe"
@%emacs_client% -n
@%emacs_client% -e "(setq default-directory \"%emacs_cd%\")"
@%emacs_client% -n  -e "(ediff-files \"%f1%\" \"%f2%\")"

Can you explain what did you need all this complexity for?


- Emacs client is used.
- File names given need not be absolute.
- You can not give use \ in the file names.
- Be nice, do not put env variables in the users environment

The rest is just comments ;-)
