Diff between folders - binary file comparison

[budric]

Hi, is there a command line utility that will do a diff between 2 folders and tell me if a file is missing from one or the other and do a binary comparison between files?

There's dirdiff port but it won't run unless I have X-win running.

Thanks,

% diff -r -q dir1 dir2

There's always the old "ls -1" (that's a one not an el) into two files, and diff the two files. :)

Thanks for the help. Works nicely.
