Does git store the read, write, execute permissions for files?

Question

I wanted to make some files in git read only. But I couldn't find any good documentation on doing this.

Does git store the read, write, execute permissions for files?

Answer 1

According to kernel.org git does not store all the permissions possible for files.

Git is a content tracker, where content is de facto defined as "whatever is relevant to the state of a typical sourcecode tree". Basically, this is just files' data and "executable" attribute.

So git stores only the content in the file and the execute bit.

(This is probably a design choice. Probably driven partly by the fact that not all file systems are the same.)

Answer 2

git update-index --chmod=+x foo.sh
