Hi Allen,

I think I can use it successfully.

> With plain find, -prune would be used like:
>
>     find . -name "foo*" -prune -o -name "*.el" -ls
>
> However, find-dired wraps everything:
>
>     (find-dired "." "-name \\"foo*\\" -prune -o -name \\"*.el\\" -ls")

I get an error when I try to eval this.  I think the backslashes should
not be doubled.

> results in the equivalent call:
>
>     find . \( -name "foo*" -prune -o -name "*.el" -ls \) -ls
>
> Notably, this will list files matching foo*

Can't you just leave out the explicit -ls in the arguments?

Also, AFAIK "-prune" is about descending into directories, not about
file names.


Michael.
