How to make GIT stop overwriting group owner?

Question

linux

The bottom line is this - when I do a git pull, I overwrite the group for a file,
for example, I have a file before git pull
-rw-r----- 1 user groupname footer.tpl
after git pull
-rw-r---- - 1 user user footer.tpl
how do I avoid overwriting the group?

Answer 1

Run git as a user whose primary group is groupname.
Well, either manually then perform chmod.
There is no other way - when creating a file (and git creates files), it is created on behalf of the ID and GID of the current user / process.

Answer 2

usermod -g groupname user

Answer 3

Read help on umask and execute umask <mask>.
After already your git commands.

Answer 4

Put on setgid bit

On most systems, if a directory's set-group-ID bit is set, newly created subfiles inherit the same group as the directory, and newly created subdirectories inherit the set-group-ID bit of the parent directory.
