Set default options

[Robert Riebisch]

Hi!

I use GNU diffutils very often. Shell is either command.com / cmd.exe or
bash.exe Is there any way to pass some default options to diff.exe? I'd
like to make "-aprNU5" default.

If you invoke diff from within emacs there is the variable `diff-switches'.

You could define an alias in both Bash and cmd.exe (but not in
command.com, AFAIK). With cmd.exe, you say something like this
(untested):

doskey diff=diff -aprNU5 $*

Yes, that sounds right. Of course, CMD won't let you use aliases
inside .BAT scripts (while 4DOS or Bash will). What is the ideal place
for Bash, inside _bashrc?
