-d::
- Remove untracked directories in addition to untracked files.
- If an untracked directory is managed by a different Git
- repository, it is not removed by default. Use -f option twice
- if you really want to remove such a directory.
+ Normally, when no <path> is specified, git clean will not
+ recurse into untracked directories to avoid removing too much.
+ Specify -d to have it recurse into such directories as well.
+ If any paths are specified, -d is irrelevant; all untracked
+ files matching the specified paths (with exceptions for nested
+ git directories mentioned under `--force`) will be removed.
-f::
--force::
If the Git configuration variable clean.requireForce is not set
to false, 'git clean' will refuse to delete files or directories
- unless given -f, -n or -i. Git will refuse to delete directories
- with .git sub directory or file unless a second -f
- is given.
+ unless given -f or -i. Git will refuse to modify untracked
+ nested git repositories (directories with a .git subdirectory)
+ unless a second -f is given.
