Git Commit Template

To use a custom template for your git commits you can add a template file into your repository. I like to have some kind of issue number first and then a short title for the commit. If I create a larger commit I always try to provide a list with the changes.

My example .gitmessage file in a repository:

T-0000 – REPLACE THIS TITLE

Changes:
- 
- 

To use this template you have to add the following into you .git/config:

[commit]
    template = .gitmessage

If you like to have a template for all your repositories you can add you template to you home folder (~/.gitmessage) and add the git configuration into you global git config (~/.git/config). But then you have to reference in the git config to the file in you home folder:

[commit]
    template = ~/.gitmessage

Signing commits

Enable globally to sign every commit:

git config --global commit.gpgsign true

Sign just a specific commit by adding the -S flag:

git commit -S -m "Foobar"

Git Submodules

Adding a new submodule

git submodule add <REPO_PATH> <SUBMODULE_NAME>

Change state of submodule

Just update all submodules to the latest commit:

git submodule update --remote --recursive

Select anything specifically:

cd <DIR_OF_SUBMODULE>
git fetch

git pull
# OR
git merge origin/master
# OR
git checkout 23e38fa

Remove/Delete a submodule

git submodule deinit <PATH_TO_SUBMODULE_FOLDER>
git rm <PATH_TO_SUBMODULE_FOLDER>
git commit -m "Remove submodule"
git push
rm -rf .git/modules/<PATH_TO_SUBMODULE_FOLDER>
