Decisions taken for simplicity:
1) It is not allowed to pass pathspec in both args and file.
Adjustments were needed for `if (!argc)` block:
This code actually means "pathspec is not present". Previously, pathspec
could only come from commandline arguments, so testing for `argc` was a
valid way of testing for the presence of pathspec. But this is no longer
true with `--pathspec-from-file`.
During the entire `--pathspec-from-file` story, I tried to keep its
behavior very close to giving pathspec on commandline, so that switching
from one to another doesn't involve any surprises.
However, throwing usage at user in the case of empty
`--pathspec-from-file` would puzzle because there's nothing wrong with
"usage" (that is, argc/argv array).
On the other hand, throwing usage in the old case also feels bad to me.
While it's less of a puzzle, I (as user) never liked the experience of
comparing my commandline to "usage", trying to spot a difference. Since
it's already known what the error is, it feels a lot better to give that
specific error to user.
Judging from [1] it doesn't seem that showing usage in this case was
important (the patch was to avoid segfault), and it doesn't fit into how
other commands react to empty pathspec (see for example `git add` with a
custom message).
Therefore, I decided to show new error text in both cases. In order to
continue testing for error early, I moved `parse_pathspec()` higher. Now
it happens before `read_cache()` / `hold_locked_index()` /
`setup_work_tree()`, which shouldn't cause any issues.

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] [--pathspec-from-file=<file> [--pathspec-file-nul]]
|
|
[--] [<pathspec>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Remove files matching pathspec 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
|
|
-------
|
|
<pathspec>...::
|
|
Files to remove. 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.
|
|
+
|
|
The command removes only the paths that are known to Git.
|
|
+
|
|
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`.
|
|
+
|
|
For more details, see the 'pathspec' entry in linkgit:gitglossary[7].
|
|
|
|
-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.
|
|
|
|
--pathspec-from-file=<file>::
|
|
Pathspec is passed in `<file>` instead of commandline args. If
|
|
`<file>` is exactly `-` then standard input is used. Pathspec
|
|
elements are separated by LF or CR/LF. Pathspec elements can be
|
|
quoted as explained for the configuration variable `core.quotePath`
|
|
(see linkgit:git-config[1]). See also `--pathspec-file-nul` and
|
|
global `--literal-pathspecs`.
|
|
|
|
--pathspec-file-nul::
|
|
Only meaningful with `--pathspec-from-file`. Pathspec elements are
|
|
separated with NUL character and all other characters are taken
|
|
literally (including newlines and quotes).
|
|
|
|
|
|
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:
|
|
|
|
----------------
|
|
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
|
|
----------------
|
|
|
|
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 move the submodules
|
|
git directory into the superprojects git directory to protect
|
|
the submodule's history. If it exists the submodule.<name> section
|
|
in the linkgit:gitmodules[5] file will also be removed and that file
|
|
will be staged (unless --cached or -n are used).
|
|
|
|
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.
|
|
|
|
If you only want to remove the local checkout of a submodule from your
|
|
work tree without committing the removal, use linkgit:git-submodule[1] `deinit`
|
|
instead. Also see linkgit:gitsubmodules[7] for details on submodule removal.
|
|
|
|
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`.
|
|
|
|
BUGS
|
|
----
|
|
Each time a superproject update removes a populated submodule
|
|
(e.g. when switching between commits before and after the removal) a
|
|
stale submodule checkout will remain in the old location. Removing the
|
|
old directory is only safe when it uses a gitfile, as otherwise the
|
|
history of the submodule will be deleted too. This step will be
|
|
obsolete when recursive submodule update has been implemented.
