BIG NOTE

if you have already pushed changes to a repository others are using

be VERY careful with changing history and then pushing again

i don't even know what ive been doing

git log

i cant read that

too much information?

git log --oneline

bad commit message?

git commit --amend -m <new-message>

forgot to add a file?

add files to the latest commit

git add <file-name>

git commit --amend --no-edit

started work on the wrong branch?

you started work on the wrong branch and want to move to a new branch

git stash

git checkout -b my-new-branch

git stash pop

undo all the things

you hate everything you've done since the last commit

commit sudoku and undo it all

git reset --hard

if you've already committed then this won't help, your shame is eternal.

your only hope is to remove the commit

remove the last commit

git reset --soft HEAD~1

revert a file to an earlier commit

find the commit hash

git log

restore the file to the previous state

git checkout <commit-hash> -- <file-name>

fubar? got a remote?

nuke the repo

cd ..

rm -rf <repo_dir>

git clone <remote_repo_url>

in all seriousness, this shouldn't be necessary
