# GIT Tricks.

Delete from git all deleted system files:

    git rm $(git ls-files --deleted)

View deleted file:

    git show HEAD^:path/to/file
    git show $(git rev-list --max-count=1 --all -- foo)^:foo
    

## File fixes

```git reset HEAD <path/to/file>``` Unstage a file. (HEAD represents the current commit)

```git reset HEAD``` Unstage all staged files.

```git checkout <path/to/file>``` To revert to the last committed version of a file but only if a) the file has been committed and b) is not currently in staging

```git checkout HEAD^ <path/to/file>``` Revert to version of file from prior commit (HEAD^ represents the prior commit). Careful: this overwrites changes to files in your working branch.

```git checkout <sha-of-commit> <path/to/file>``` Revert to version of file from specific commit

## Undo commits

only use it to back out of local commits that haven not been pushed to a shared repository.

```git reset --soft HEAD^``` Undo last commit of entire repo, but leave files staged.

```git reset --hard HEAD^``` Completely blow away last commit. Changes files to state of previous commit.

```git reset --hard HEAD^^``` Completely blow away last two commits. Changes files to state of previous commit.

```git reset --hard HEAD^^^``` Completely blow away last three commits. Changes files to state prior to last third commit.

```git reset --hard <sha-of-commit>``` Returns files to state they were in after specificed commit
