git not allowing 744 as permissions for a file

Auriane Reverdell· Jan 24, 2023, 15:48 UTC · lore

Hi,

git doesn't allow to add the execution permission on a file only for the user. A chmod 744 on a file will transform into 755 when added to git. This can potentially lead to security problems on certain systems. Is there a way to fix that? I'll be happy to do so if somebody shows me where to do it.

Auriane R.

No, there isn't. Git tracks only whether the executable bit is set. All file modes are either 644 or 755.

If you need the permissions or ownership on the file to be different, you can do that by using a script to copy the files into another location with the proper permissions or ownership instead of using the copies in the repository. For example, I do this with my dotfiles such that the files have the correct permissions.
