GIT-cheat-sheet

Undo git commit & redo

git reset HEAD~

Ignore versioned files

git rm -r --cached path/ignore/dir

Convert last commit to unstaged changes (uncommit)

git reset HEAD^

Rename branch

git branch -m [old_name] new_name

Rebase to specific commit

git rebase --onto <new-parent> <old-parent>

Merge 2 commits

Say the history is

git log --pretty=oneline

a931ac7c808e2471b22b5bd20f0cad046b1c5d0d c

b76d157d507e819d7511132bdb5a80dd421d854f b

df239176e1a2ffac927d8b496ea00d5488481db5 a

That is, A was the first commit, then B, and finally C. Running git rebase --interactive HEAD~2 gives you an editor with

pick b76d157 b pick a931ac7 c

Changing c's pick to squash will result in the commit merging with it's predecessor

pick b76d157 b squash a931ac7 c

and save-quitting your editor, you'll get another editor. When you save and quit, the contents of the edited file become commit message of the new combined commit.

Set editor

export EDITOR=vim

Rebase to current remote master

git pull --rebase origin master

Create a branch from specific commit in different branch

git checkout -b <branch_name> <commit>

Reset branch to given commit

git reset --hard COMMIT_ID

Delete branch

git branch -d branch_name

Undo “git commit --amend” done instead of “git commit”

  1. git reset --soft HEAD@{1}
  2. commit properly

Accept all remote changes in all conflicts

grep -lr '<<<<<<<' . | xargs git checkout --theirs

git add .

git rebase --continue

Removing an entire commit

git rebase -p --onto SHA^ SHA

Recursively converting files from dos line endings to unix line endings

find . -name "*" -type f -exec dos2unix {} \;.
