The "clean" command:
Usage: fossil clean ?OPTIONS? ?PATH ...?
Delete all "extra" files in the source tree. "Extra" files are files
that are not officially part of the checkout. If one or more PATH
arguments appear, then only the files named, or files contained with
directories named, will be removed.
If the --prompt option is used, prompts are issued to confirm the
permanent removal of each file. Otherwise, files are backed up to the
undo buffer prior to removal, and prompts are issued only for files
whose removal cannot be undone due to their large size or due to
--disable-undo being used.
The --force option treats all prompts as having been answered yes,
whereas --no-prompt treats them as having been answered no.
Files matching any glob pattern specified by the --clean option are
deleted without prompting, and the removal cannot be undone.
No file that matches glob patterns specified by --ignore or --keep will
ever be deleted. Files and subdirectories whose names begin with "."
are automatically ignored unless the --dotfiles option is used.
The default values for --clean, --ignore, and --keep are determined by
the (versionable) clean-glob, ignore-glob, and keep-glob settings.
The --verily option ignores the keep-glob and ignore-glob settings and
turns on the options --force, --emptydirs, --dotfiles, --disable-undo,
and --no-dir-symlinks. Use the --verily option when you really want
to clean up everything. Extreme care should be exercised when using
the --verily option.
--allckouts Check for empty directories within any checkouts
that may be nested within the current one. This
option should be used with great care because the
empty-dirs setting (and other applicable settings)
belonging to the other repositories, if any, will
not be checked.
--case-sensitive <BOOL> override case-sensitive setting
--dirsonly Only remove empty directories. No files will
be removed. Using this option will automatically
enable the --emptydirs option as well.
--disable-undo WARNING: This option disables use of the undo
mechanism for this clean operation and should be
used with extreme caution.
--dotfiles Include files beginning with a dot (".").
--emptydirs Remove any empty directories that are not
explicitly exempted via the empty-dirs setting
or another applicable setting or command line
argument. Matching files, if any, are removed
prior to checking for any empty directories;
therefore, directories that contain only files
that were removed will be removed as well.
-f|--force Remove files without prompting.
-i|--prompt Prompt before removing each file. This option
implies the --disable-undo option.
-x|--verily WARNING: Removes everything that is not a managed
file or the repository itself. This option
implies the --force, --emptydirs, --dotfiles, and
--disable-undo, and --no-dir-symlinks options.
Furthermore, it completely disregards the keep-glob
and ignore-glob settings. However, it does honor
the --ignore and --keep options.
--clean <CSG> WARNING: Never prompt to delete any files matching
this comma separated list of glob patterns. Also,
deletions of any files matching this pattern list
cannot be undone.
--ignore <CSG> Ignore files matching patterns from the
comma separated list of glob patterns.
--keep <CSG> Keep files matching this comma separated
list of glob patterns.
-n|--dry-run Delete nothing, but display what would have been
--no-prompt This option disables prompting the user for input
and assumes an answer of 'No' for every question.
--no-dir-symlinks Disables support for directory symlinks.
--temp Remove only Fossil-generated temporary files.
-v|--verbose Show all files as they are removed.
