git rebase -i [commit hash]^	Interactively rebase starting from the parent commit, where [commit hash]^ specifies the parent commit
git pull origin [source branch] --rebase	Pull changes from a remote repository using the rebase strategy. Default is merge.

Fixing mistakes & destructive

Command	Description
git reset --hard origin/[target branch]	Reset the local branch to the origin branch's state. Caution: your local changes will be lost.
git reset --soft HEAD~1	Undo the last local commit. The --soft flag keeps the changes, if you don't need to keep them, you can use the --hard instead. Caution, the latter is a descructive command.
git commit --amend	Modify the most recent commit. Can be used to edit message or add more files to that commit. Caution, this changes the commit hash, so do this only while it was not yet pushed to a shared branch.
git revert HEAD~1	Create a new commit undoing the last commit's changes.
git reflog	List all the git actions that were executed before. Useful to find a lost commit, then you can try to recover it.
git bisect start	Useful to find the buggy commit (that possible introduces some bug). After this, you use `git bisect [good
git branch --merged | egrep -v "(*|master|dev)" | xargs git branch -d	Delete already merged branches but master and dev in this example.
git clean -df	Remove untracked files and directories from the working tree. Add n to the flags to list all files that would be removed.
