Diffing between two entire directories/projects in hg or git?
I inherited a project originally stored in CVS with all the revisions. I made quite a few edits, and I'm trying to compare all the changes I made in the original directory, in regards to new files added versus the old ones.
Is there some sort of utility for hg/git where I can do a tree diff, or something of that nature? So that say, there's a mark between newly added files, deleted files, am I asking for too much?
Answer
To simply create a diff patch in git's diff format from two arbitrary files or directories, without any fancy repository stuff or version control:
git diff --no-index some/path other/path > some_filename
Jakub Narębski's comment on knittl's answer hinted at the answer... For simplicity's sake, that's the full command.
The > part creates a file and redirects the output to it. If you don't want a file and just want the output printed in your console so you can copy it, just remove the > some_filename part.
For convenient copying and pasting, if you've already cded to a directory containing the original directory/file named a and the modified directory b, it'll be:
git diff --no-index a b > patch
