[git] Updating and committing only a file's permissions using git version control

Just turned an some.sh file into an executable (chmod 755 ...), the permissions were updated but not the content. Is there a way to commit the file into git, so that the executable bit will be restored/set on clone / checkout / pull ?

Update: how can I track that the new permissions were submitted to github?

This question is related to git

The answer is


@fooMonster article worked for me

# git ls-tree HEAD
100644 blob 55c0287d4ef21f15b97eb1f107451b88b479bffe    script.sh

As you can see the file has 644 permission (ignoring the 100). We would like to change it to 755:

# git update-index --chmod=+x script.sh

commit the changes

# git commit -m "Changing file permissions"
[master 77b171e] Changing file permissions
0 files changed, 0 insertions(+), 0 deletions(-)
mode change 100644 => 100755 script.sh

Not working for me.

The mode is true, the file perms have been changed, but git says there's no work to do.

git init
git add dir/file
chmod 440 dir/file
git commit -a

The problem seems to be that git recognizes only certain permission changes.
