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

git diff -G"." 

The -G flag filters out any file where a line that matches a regular expression has not been added or removed. In this case the regular expression provided is "." which matches any line. So the argument -G"." will filter out files where no lines have been added or removed.

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

Answer 2

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
