Git notes

Change git remote:

With or without ssh keys added to your user account..

git remote set-url origin git@gitlab01.iwillfearnoevil.com:monitoring/nmsui.git
or:
git remote set-url origin https://gitlab01.iwillfearnoevil.com/monitoring/nmsui.git

Sort git branches by last commit

git for-each-ref --sort=committerdate refs/heads/ --format='%(HEAD) %(color:yellow)%(refname:short)%(color:reset) - %(color:red)%(objectname:short)%(color:reset) - %(contents:subject) - %(authorname) (%(color:green)%(committerdate:relative)%(color:reset))'

Show git commit hashes for each branch sorted by date

git for-each-ref --sort=-committerdate refs/heads/

Do a git diff between two branches

git diff <branch>..origin/<branch2>

Update Submodules

pull-latest-changes-for-all-git-submodules

git submodule update --recursive --init
git submodule update --recursive --remote

Checkout specific commit hash

This can be useful when the hash is not in the expected branch, or when you are in a detached head state

git clone [remote_address_here] my_repo
cd my_repo
git reset --hard [ENTER HERE THE COMMIT HASH YOU WANT]

Change submodule URL

This is very much a hammer way of doing this. I have seen elegant ways online, but they seem inconsistent when something goes wrong. This way is reproducible as far as I am concerned.

This example assumes that directory/ is where your submodule lives.

edit .gitmodule
change values
rm -rf directory/
git submodule update --init --recursive --remote
cd into directory/
git pull whatever submodule branch you need
cd ..
git add -A
git commit -m 'save new submodule changes'
git push
