!! be very careful with these !! you may end up deleting what you don't want to

remove untracked

git clean -f -d

CAUTION: as above but removes ignored files like config.

git clean -f -x -d

CAUTION: as above, but cleans untracked and ignored files through the entire repo (without :/, the operation affects only the current directory)

git clean -fxd :/

Delete all local branches but keeping others like "develop" and "master":

git branch | grep -v "develop" | grep -v "master" | grep -v "main" | xargs git branch -D

removes staged and working directory changes

git reset --hard

Setting your branch to exactly match the remote branch can be done in two steps:

git fetch origin git reset --hard origin/master

If you want to save your current branch's state before doing this (just in case), you can do:

git commit -a -m "Saving my work, just in case" git branch my-saved-work
