Git

Ignore changes to a tracked file:

git update-index --assume-unchanged <file>

Start tracking changes to an ignored file (above):

git update-index --no-assume-unchanged <file>

Undo the last commit:

git reset HEAD~1 --soft

Undo the first (unpushed) commit of a repository:

git update-ref -d HEAD

Verify objects in database and optimize:

git fsck && git gc --aggressive --prune=now

Change branch:

git checkout <branch name>

Create a new local branch based off your current one:

git checkout -b <branch name>

Water current branch with changes from other branch:

git merge <other branch name>

Squash feature branch changes into current one:

git merge --no-commit --squash <feature branch name>

Delete an unmerged local branch, i.e. force delete:

git branch -D <branch name>

Delete a remote branch:

git push <remote name> :<branch name>

Get branch names you may own:

git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)' | sort -k5n -k2M -k3n -k4n | grep <git username>

Create patch from current changes:

git diff > <patch name>.patch

Note: To ensure new files are added to the patch run git add . and then git diff --cached > <patch name>.patch. Add the --binary flag when adding non-text files.

Apply patch:

git apply <patch name>.patch

Find the commit that deleted a file:

git log --full-history -- path/to/file.js

Search for commits that added/deleted a string:

git log -S 'string here'
