Currently using "git rm" on a submodule - populated or not - fails with this error: fatal: git rm: '<submodule path>': Is a directory This made sense in the past as there was no way to remove a submodule without possibly removing unpushed parts of the submodule's history contained in its .git directory too, so erroring out here protected the user from possible loss of data. But submodules cloned with a recent git version do not contain the .git directory anymore, they use a gitfile to point to their git directory which is safely stored inside the superproject's .git directory. The work tree of these submodules can safely be removed without losing history, so let's teach git to do so. Using rm on an unpopulated submodule now removes the empty directory from the work tree and the gitlink from the index. If the submodule's directory is missing from the work tree, it will still be removed from the index. Using rm on a populated submodule using a gitfile will apply the usual checks for work tree modification adapted to submodules (unless forced). For a submodule that means that the HEAD is the same as recorded in the index, no tracked files are modified and no untracked files that aren't ignored are present in the submodules work tree (ignored files are deemed expendable and won't stop a submodule's work tree from being removed). That logic has to be applied in all nested submodules too. Using rm on a submodule which has its .git directory inside the work trees top level directory will just error out like it did before to protect the repository, even when forced. In the future git could either provide a message informing the user to convert the submodule to use a gitfile or even attempt to do the conversion itself, but that is not part of this change.

NAME
|
|
----
|
|
git-rm - Remove files from the working tree and from the index
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git rm' [-f | --force] [-n] [-r] [--cached] [--ignore-unmatch] [--quiet] [--] <file>...
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Remove files from the index, or from the working tree and the index.
|
|
`git rm` will not remove a file from just your working directory.
|
|
(There is no option to remove a file only from the working tree
|
|
and yet keep it in the index; use `/bin/rm` if you want to do that.)
|
|
The files being removed have to be identical to the tip of the branch,
|
|
and no updates to their contents can be staged in the index,
|
|
though that default behavior can be overridden with the `-f` option.
|
|
When `--cached` is given, the staged content has to
|
|
match either the tip of the branch or the file on disk,
|
|
allowing the file to be removed from just the index.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
<file>...::
|
|
Files to remove. Fileglobs (e.g. `*.c`) can be given to
|
|
remove all matching files. If you want git to expand
|
|
file glob characters, you may need to shell-escape them.
|
|
A leading directory name
|
|
(e.g. `dir` to remove `dir/file1` and `dir/file2`) can be
|
|
given to remove all files in the directory, and recursively
|
|
all sub-directories,
|
|
but this requires the `-r` option to be explicitly given.
|
|
|
|
-f::
|
|
--force::
|
|
Override the up-to-date check.
|
|
|
|
-n::
|
|
--dry-run::
|
|
Don't actually remove any file(s). Instead, just show
|
|
if they exist in the index and would otherwise be removed
|
|
by the command.
|
|
|
|
-r::
|
|
Allow recursive removal when a leading directory name is
|
|
given.
|
|
|
|
\--::
|
|
This option can be used to separate command-line options from
|
|
the list of files, (useful when filenames might be mistaken
|
|
for command-line options).
|
|
|
|
--cached::
|
|
Use this option to unstage and remove paths only from the index.
|
|
Working tree files, whether modified or not, will be
|
|
left alone.
|
|
|
|
--ignore-unmatch::
|
|
Exit with a zero status even if no files matched.
|
|
|
|
-q::
|
|
--quiet::
|
|
`git rm` normally outputs one line (in the form of an `rm` command)
|
|
for each file removed. This option suppresses that output.
|
|
|
|
|
|
DISCUSSION
|
|
----------
|
|
|
|
The <file> list given to the command can be exact pathnames,
|
|
file glob patterns, or leading directory names. The command
|
|
removes only the paths that are known to git. Giving the name of
|
|
a file that you have not told git about does not remove that file.
|
|
|
|
File globbing matches across directory boundaries. Thus, given
|
|
two directories `d` and `d2`, there is a difference between
|
|
using `git rm 'd*'` and `git rm 'd/*'`, as the former will
|
|
also remove all of directory `d2`.
|
|
|
|
REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM
|
|
--------------------------------------------------------
|
|
There is no option for `git rm` to remove from the index only
|
|
the paths that have disappeared from the filesystem. However,
|
|
depending on the use case, there are several ways that can be
|
|
done.
|
|
|
|
Using ``git commit -a''
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
If you intend that your next commit should record all modifications
|
|
of tracked files in the working tree and record all removals of
|
|
files that have been removed from the working tree with `rm`
|
|
(as opposed to `git rm`), use `git commit -a`, as it will
|
|
automatically notice and record all removals. You can also have a
|
|
similar effect without committing by using `git add -u`.
|
|
|
|
Using ``git add -A''
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
When accepting a new code drop for a vendor branch, you probably
|
|
want to record both the removal of paths and additions of new paths
|
|
as well as modifications of existing paths.
|
|
|
|
Typically you would first remove all tracked files from the working
|
|
tree using this command:
|
|
|
|
Submodules
|
|
~~~~~~~~~~
|
|
Only submodules using a gitfile (which means they were cloned
|
|
with a git version 1.7.8 or newer) will be removed from the work
|
|
tree, as their repository lives inside the .git directory of the
|
|
superproject. If a submodule (or one of those nested inside it)
|
|
still uses a .git directory, `git rm` will fail - no matter if forced
|
|
or not - to protect the submodule's history.
|
|
|
|
A submodule is considered up-to-date when the HEAD is the same as
|
|
recorded in the index, no tracked files are modified and no untracked
|
|
files that aren't ignored are present in the submodules work tree.
|
|
Ignored files are deemed expendable and won't stop a submodule's work
|
|
tree from being removed.
|
|
|
|
----------------
|
|
git ls-files -z | xargs -0 rm -f
|
|
----------------
|
|
|
|
and then untar the new code in the working tree. Alternately
|
|
you could 'rsync' the changes into the working tree.
|
|
|
|
After that, the easiest way to record all removals, additions, and
|
|
modifications in the working tree is:
|
|
|
|
----------------
|
|
git add -A
|
|
----------------
|
|
|
|
See linkgit:git-add[1].
|
|
|
|
Other ways
|
|
~~~~~~~~~~
|
|
If all you really want to do is to remove from the index the files
|
|
that are no longer present in the working tree (perhaps because
|
|
your working tree is dirty so that you cannot use `git commit -a`),
|
|
use the following command:
|
|
|
|
----------------
|
|
git diff --name-only --diff-filter=D -z | xargs -0 git rm --cached
|
|
----------------
|
|
|
|
EXAMPLES
|
|
--------
|
|
`git rm Documentation/\*.txt`::
|
|
Removes all `*.txt` files from the index that are under the
|
|
`Documentation` directory and any of its subdirectories.
|
|
+
|
|
Note that the asterisk `*` is quoted from the shell in this
|
|
example; this lets git, and not the shell, expand the pathnames
|
|
of files and subdirectories under the `Documentation/` directory.
|
|
|
|
`git rm -f git-*.sh`::
|
|
Because this example lets the shell expand the asterisk
|
|
(i.e. you are listing the files explicitly), it
|
|
does not remove `subdir/git-foo.sh`.
