View permissions change in Git

Question

Before I commit some files, how can I see the file permission changes to files? I have some files that git status says had changed and should be added to commit but git diff doesn't show anything. Thanks

File read, write and execute permissions. I'll update the question. — Clutch, Feb 23 '11 at 17:25
@Arrowmaster No, it tracks the full set of Unix file permissions. See [this answer](http://stackoverflow.com/questions/737673/how-to-read-the-mode-field-of-git-ls-trees-output) — Abizern, Feb 23 '11 at 17:32
@Abizern: While all the output shows full unix file permissions, trust me when I say that 755 and 644 are the only possible permissions it will show. If you don't believe me test it for yourself. — Arrowmaster, Feb 23 '11 at 17:38
Dude, changing the question after it's been answered is not a good thing. — Abizern, Feb 23 '11 at 22:36

git log --summary will get you what you're looking for, I think. The flag will, "Output a condensed summary of extended header information such as creations, renames and mode changes." Note the example below:

$ git log --summary

 mode change 100644 => 100755 matrix.cc

 create mode 100644 matrix.cc

I changed the question a little, sorry about that. – Clutch Feb 23 '11 at 18:51 — Clutch, Feb 23 '11 at 18:51

Well, since the question has been edited to ask something different, here's a different answer:

git status -v will list mode changes as well as diffs. You can filter this down to just mode changes by running it through grep with a context filter: git status -v | grep '^old mode' -C 1 (sample result below)

diff --git a/matrix.cc b/matrix.cc
old mode 100644
new mode 100755

A straightforward answer to your question:

git diff --summary

will output something like this:

mode change 100644 => 100755 assets/README.md
mode change 100644 => 100755 assets/css/app.css
mode change 100644 => 100755 assets/js/app-monitor.js
mode change 100644 => 100755 assets/js/app.js`

And this `git diff --summary | grep --color 'mode change 100644 => 100755' | cut -d' ' -f7 | xargs chmod -x` would remove the execute bit so git doesn't see the files as changed. ref. https://wiki.freephile.org/wiki/Git/hacks#Ignore_File_Mode – Greg Rundlett Jan 13 '19 at 05:03

I used this

git status --porcelain=2 | grep '100755 100755 100644' | cut -d' ' -f9

you can change the three masks 100755 100755 100644 with ones you are looking for
