Show git diff, ignoring file permission changes?

Question

I have run several chmod in my live server. Right now when I do a git diff there, I see lots of old mode 100644 new mode 100755

I have also changed some files there. But I would just git diff just to show the changes on the files, ignoring the file permissions changes.

How can I do that? BTW, I don't want GIT to ignore those file permissions changes. Actually I want to commit them, I just want git diff to not show them for a very specific moment.

Answer 1

This will tell git to ignore permissions:

git config core.filemode false

to filter them in result of diff but not ignore them

git filter-branch -f --tree-filter 'find * -type f | xargs chmod 644 ' -- --all

Answer 2

git diff -G.

Note: the period at the end is part of the command.

You will need (I think) at least Git version 1.7.10 for this to work. 1.7.2 is too old, at least.
