Git rm Overview
Specifies the target files to remove. The option value can be an individual file, a space delimited list of files
file1 file2 file3, or a wildcard file glob
-f option is used to override the safety check that Git makes to ensure that the files in
HEAD match the current content in the staging index and working directory.
The "dry run" option is a safeguard that will execute the
git rm command but not actually delete the files. Instead it will output which files it would have removed.
-r option is shorthand for 'recursive'. When operating in recursive mode
git rm will remove a target directory and all the contents of that directory.
The separator option is used to explicitly distinguish between a list of file names and the arguments being passed to
git rm. This is useful if some of the file names have syntax that might be mistaken for other options.
The cached option specifies that the removal should happen only on the staging index. Working directory files will be left alone.
This causes the command to exit with a 0 sigterm status even if no files matched. This is a Unix level status code. The code 0 indicates a successful invocation of the command. The
--ignore-unmatch option can be helpful when using
git rm as part of a greater shell script that needs to fail gracefully.
The quiet option hides the output of the
git rm command. The command normally outputs one line for each file removed.
How to undo git rm
git rm is not a permanent update. The command will update the staging index and the working directory. These changes will not be persisted until a new commit is created and the changes are added to the commit history. This means that the changes here can be "undone" using common Git commands.
git reset HEAD
A reset will revert the current staging index and working directory back to the
HEAD commit. This will undo a
git checkout .
file> argument given to the command can be exact paths, wildcard file glob patterns, or exact directory names. The command removes only paths currently commited to the Git repository.
Wildcard file globbing matches across directories. It is important to be cautious when using wildcard globs. Consider the examples:
directory*. The first example will remove all sub files of
directory/ whereas the second example will remove all sibling directories like
directory_whatever which may be an unexpected result.
The scope of git rm
git rm command operates on the current branch only. The removal event is only applied to the working directory and staging index trees. The file removal is not persisted to the repository history until a new commit is created.
Why use git rm instead of rm
A Git repository will recognize when a regular shell
rm command has been executed on a file it is tracking. It will update the working directory to reflect the removal. It will not update the staging index with the removal. An additional
git add command will have to be executed on the removed file paths to add the changes to the staging index. The
git rm command acts a shortcut in that it will update the working directory and the staging index with the removal.
git rm Documentation/\*.txt
This example uses a wildcard file glob to remove all
*.txt files that are children of the
Documentation directory and any of its subdirectories.
Note that the asterisk * is escaped with slashes in this example; this is a guard that prevents the shell from expanding the wildcard. The wildcard then expands the pathnames of files and subdirectories under the
git rm -f git-*.sh
This example uses the force option and targets all wildcard
git-*.sh files. The force option explicitly removes the target files from both the working directory and staging index.
How to remove files no longer in the filesystem
As stated above in "Why use
git rm instead of
git rm is actually a convenience command that combines the standard shell
git add to remove a file from the working directory and promote that removal to the staging index. A repository can get into a cumbersome state in the event that several files have been removed using only the standard shell
If intentions are to record all the explicitly removed files as part of the next commit,
git commit -a will add all the removal events to the staging index in preparation of the next commit.
If however, intentions are to persistently remove the files that were removed with the shell
rm, use the following command:
git diff --name-only --diff-filter=D -z | xargs -0 git rm --cached
This command will generate a list of the removed files from the working directory and pipe that list to
git rm --cached which will update the staging index.
