Stash

save untracked files

git stash -u "Message"

Others

uisng git stash or git stash save to save current working directory status into stash
You can add a message after git stash save as a reminder, such as:
git stash save "git guidebook half-way, till the stash part"

git stash list can list out all your stashes

git stash apply will apply the most recent stash,
meanwhile git stash apply stash@{n} can apply the stash at the position {n} listed by git stash list.

But the apply command mentioned above can't reapply the staged changes,
you need add an --index flag after git stash apply to do this

The apply option only tries to apply the stashed work,
you continued to have it on your stack.
To remove it, you can run git stash drop with the name of the stash to remove, like:
git stash drop stash@{2}

Or you can use git stash pop stash@{2} to apply a stash and drop it immediately after that.

Advancing usage

using --keep-index option to stash save command so that git won't stash anything in the staged area.

By default, git stash will only store files that are already in the index.
If you specify --include-untracked or -u, git will also stash any untracked files you have created.

If you don't want to stash everything, you can use --patch flag, then you can select interactively which files you want to stash in a prompt.

At last, if the branch you stashed from made some commits and is conflict with your stash.
You can use git stash branch <your_branch_name> to make a branch from the commit where you stashed your work,
and then apply your stash on it, drop the stash if successfully applied.

If you want to clean the directory, you can use git stash --all to add all files include ignored file into git stash.

To empty the entire stash stacks, you use git stash clear

Clean

Yet git will offer you another command to clean your directory: clean

To remove all the untracked files in your working directory, you can run git clean -f -d,
which removes all untracked files and directories,
-f means force

If you want to ensure not to accidentally remove important file,
you can use git clean -d -n to do a dry run,
the -n option will show what will be deleted without delete them.

By default, the git clean command will only remove untracked files that are not ignored.
To remove all the ignored file, add an -x to the clean command.

You can also add an -i flag to prompt out an interactive interface,
through which you can confirm the deletion of file one by one, to avoid mistake.
