How do I remove files saying “old mode 100755 new mode 100644” from unstaged changes in Git?

Question

For some reason, when I initially did a pull from the repository for a git project of mine, I got a ton of files in my working copy that have no discernible changes made to them, but keep showing up in my unstaged changes area.

I'm using Git Gui on Windows xp, and when I go to look at the file to see what has changed. All I see is:

old mode 100755  
new mode 100644  

Does anyone know what this means?

How can I get these files out of my list of unstaged changes? (Very annoying to have to go through 100's of files, just to pick out files I've recently edited and want to commit).

Answer 1

That looks like unix file permissions modes to me (755=rwxr-xr-x, 644=rw-r--r--) - the old mode included the +x (executable) flag, the new mode doesn't.

This msysgit issue's replies suggests setting core.filemode to false in order to get rid of the issue:

git config core.filemode false

Answer 2

Setting core.filemode to false does work, but make sure the settings in ~/.gitconfig aren't being overridden by those in .git/config.

Answer 3

I've encountered this problem when copying a git repo with working files from an old hard drive a couple times. The problem stems from the fact that the owner and permissions changed from the old drive/machine to the new one. The long and short of it is, run the following commands to straighten things out (thanks to this superuser answer):

sudo chmod -R -x . # remove the executable bit from all files

The former command will actually resolve the differences that git diff reported, but will revoke your ability to list the directories, so ls ./ fails with ls: .: Permission denied. To fix that:

sudo chmod -R +X . # add the executable bit only for directories

The bad news is that if you do have any files you want to keep executable, such as .sh scripts, you'll need to revert those. You can do that with the following command for each file:

chmod +x ./build.sh # where build.sh is the file you want to make executable again

This usually happens when the repo is cloned between Windows and Linux/Unix machines.

Just tell git to ignore filemode change. Here are several ways to do so:

1. Config ONLY for current repo:

    git config core.filemode false
   

2. Config globally:

    git config --global core.filemode false
   

3. Add in ~/.gitconfig:

    [core]
         filemode = false
   

Just select one of them.

Answer 5

It seems you have changed some permissions of the directory. I did the following steps to restore it.

$  git diff > backup-diff.txt                ### in case you have some other code changes 

$  git checkout .

Answer 6

This worked for me:

git ls-files -m | xargs -L 1 chmod 644

Answer 7

You could try git reset --hard HEAD to reset the repo to the expected default state.

Answer 8

I have faced the same issue. And this save my life: https://gist.github.com/jtdp/5443498

git diff -p -R --no-color \
| grep -E "^(diff|(old|new) mode)" --color=never  \
| git apply`

This solution will change the git file permissions from 100755 to 100644 and push changes back to the bitbucket remote repo.

1. Take a look at your repo's file permissions: git ls-files --stage

2. If 100755 and you want 100644

Then run this command: git ls-files --stage | sed 's/\t/ /g' | cut -d' ' -f4 | xargs git update-index --chmod=-x

3. Now check your repo's file permissions again: git ls-files --stage

4. Now commit your changes:

git status

git commit -m "restored proper file permissions"

git push

Answer 10

This happens when you pull and all files were executable in the remote repository. Making them executable again will set everything back to normal again.

chmod +x <yourfile> //For one file
chmod +x folder/* // For files in a folder

You might need to do:

chmod -x <file> // Removes execute bit

instead, for files that was not set as executable and that was changed because of the above operation. There is a better way to do this but this is just a very quick and dirty fix.

Answer 11

You can use the following command to change your file mode back. git add --chmod=+x -- filename Then commit to the branch.

Answer 12

The accepted answer to set git config core.filemode false, works, but with consequences. Setting core.filemode to false tells git to ignore any executable bit changes on the filesystem so it won't view this as a change. If you do need to stage an executable bit change for this repository anytime in the future, you would have to do it manually, or set core.filemode back to true.

A less consequential alternative, if all the modified files should have mode 100755, is to do something like

chmod 100755 $(git ls-files --modified)

which just does exactly the change in mode, no more, no less, without additional implications.

(in my case, it was due to a OneDrive sync with my filesystem on MacOS; by not changing core.filemode, I'm leaving the possibility open that the mode change might happen again in the future; in my case, I'd like to know if it happens again, and changing core.filemode will hide it from me, which I don't want)

Answer 13

I had just the one troublesome file with the changed permissions. To roll it back individually, I just deleted it manually with rm <file> and then did a checkout to pull a fresh copy.

Luckily I had not staged it yet.

If I had I could have run git reset -- <file> before running git checkout -- <file>

Answer 14

I just ran into this issue when diffing my branch with master. Git returned one 'mode' error when I expected my branch to be identical to master. I fixed by deleting the file and then merging master in again.

First I ran the diff:

git checkout my-branch
git diff master

This returned:

diff --git a/bin/script.sh b/bin/script.sh
old mode 100755
new mode 100644

I then ran the following to fix:

rm bin/script.sh
git merge -X theirs master

After this, git diff returned no differences between my-branch and master.
