How do I make Git ignore file mode (chmod) changes

Question

I have a project in which I have to change the mode of files with chmod to 777 while developing, but which should not change in the main repo.

Git picks up on chmod -R 777 . and marks all files as changed. Is there a way to make Git ignore mode changes that have been made to files?

Answer 1

If you have used chmod command already then check the difference of file, It shows previous file mode and current file mode such as:

new mode : 755

old mode : 644

set old mode of all files using below command

sudo chmod 644 .

now set core.fileMode to false in config file either using command or manually.

git config core.fileMode false

then apply chmod command to change the permissions of all files such as

sudo chmod 755 .

and again set core.fileMode to true.

git config core.fileMode true

For best practises don't Keep core.fileMode false always.

undo mode change in working tree:

git diff --summary | grep --color 'mode change 100755 => 100644' | cut -d' ' -f7- | xargs -d'\n' chmod +x
git diff --summary | grep --color 'mode change 100644 => 100755' | cut -d' ' -f7- | xargs -d'\n' chmod -x

Or in mingw-git

git diff --summary | grep  'mode change 100755 => 100644' | cut -d' ' -f7- | xargs -e'\n' chmod +x
git diff --summary | grep  'mode change 100644 => 100755' | cut -d' ' -f7- | xargs -e'\n' chmod -x

Answer 3

If you want to set filemode to false in config files recursively (including submodules) : find -name config | xargs sed -i -e 's/filemode = true/filemode = false/'

Answer 4

You can configure it globally:

git config --global core.filemode false

If the above doesn't work for you, the reason might be your local configuration overrides the global configuration.

Remove your local configuration to make the global configuration take effect:

git config --unset core.filemode

Alternatively, you could change your local configuration to the right value:

git config core.filemode false

Answer 5

By definining the following alias (in ~/.gitconfig) you can easily temporarily disable the fileMode per git command:

nfm = "!f(){ git -c core.fileMode=false $@; };f"

When this alias is prefixed to the git command, the file mode changes won't show up with commands that would otherwise show them. For example:

git nfm status

Answer 6

If

git config --global core.filemode false

does not work for you, do it manually:

cd into yourLovelyProject folder

cd into .git folder:

cd .git

edit the config file:

nano config

change true to false

[core]
        repositoryformatversion = 0
        filemode = true

->

[core]
        repositoryformatversion = 0
        filemode = false

save, exit, go to upper folder:

cd ..

reinit the git

git init

you are done!
