Bash-git-commands

Git commands that are useful for bash scripts.

• Retrieve the hash for the current commit inside whatever branch we are in
• This also works for submodules as long as you are within the submodule directory in question

git rev-parse HEAD

• Change the git remote from http(s) to git@ can be done this way:

sed -i 's|https://URL/|git@URL:|g' ./.git/config

• If you want to update the submodules

sed -i 's|https://URL/|git@URL:|g' ./.gitmodules
git submodule sync --recursive
sed -i 's|https://URL/|git@URL:|g' ./.git/modules/PATH/config

If you want to create a PR/MR in gitlab via the CLI

• you must have write privs
• Make very sure you are in a NEW branch so you do not screw things up.
  • Using a date or epoch timestamp is reasonable

git branch foo
git checkout foo
--- Make your changes ---
git add -A
git commit -m "Generic commit message"
git push -o merge_request.create -o merge_request.title="A spiffy title" -o merge_request.description="A short description"
