`git clean` Delete untracked files from the working folder

Removes files Git does not track, such as build output or stray new files. It is permanent, so do a dry run first.

Synopsis

git clean [OPTION]... [PATH]...

Option or form	What it does
`-n, --dry-run`	Show what would be deleted without deleting
`-f, --force`	Actually delete. Required by default
`-d`	Include untracked folders
`-x`	Also remove files ignored by .gitignore
`-i`	Choose interactively

Preview what would go

git clean -n

Would remove notes.txt

Delete untracked files

git clean -f

Delete untracked files and folders

git clean -fd

Wipe build output too

git clean -fdx

Pick from a list

git clean -i

Files removed by clean are not in the Trash and are not in Git, so they cannot be recovered.
-x also deletes ignored files like .env and node_modules.
Always run with -n first and read the list.
