git checkout-index [-u] [-q] [-a] [-f] [-n] [--prefix=<string>] [--stage=<number>|all] [--temp] [--ignore-skip-worktree-bits] [-z] [--stdin] [--] [<file>...]

Options

-u--index

update stat information for the checked out entries in the index file.

-q--quiet

be quiet if files exist or are not in the index

-f--force

forces overwrite of existing files

-a--all

checks out all files in the index except for those with the skip-worktree bit set (see --ignore-skip-worktree-bits). Cannot be used together with explicit filenames.

-n--no-create

Don’t checkout new files, only refresh files already checked out.

--prefix

When creating files, prepend <string> (usually a directory including a trailing /)

--stage

Instead of checking out unmerged entries, copy out the files from the named stage. <number> must be between 1 and 3. Note: --stage=all automatically implies --temp.

--temp

Instead of copying the files to the working directory, write the content to temporary files. The temporary name associations will be written to stdout.

--ignore-skip-worktree-bits

Check out all files, including those with the skip-worktree bit set.

--stdin

Instead of taking a list of paths from the command line, read the list of paths from the standard input. Paths are separated by LF (i.e. one path per line) by default.

-z

Only meaningful with --stdin; paths are separated with NUL character instead of LF.

DESCRIPTION

Copies all listed files from the index to the working directory (not overwriting existing files).

USING --TEMP OR --STAGE=ALL

When --temp is used (or implied by --stage=all) git checkout-index will create a temporary file for each index entry being checked out. The index will not be updated with stat information. These options can be useful if the caller needs all stages of all unmerged entries so that the unmerged files can be processed by an external merge tool.

A listing will be written to stdout providing the association of temporary file names to tracked path names. The listing format has two variations:

1.tempname TAB path RS

The first format is what gets used when --stage is omitted or is not --stage=all. The field tempname is the temporary file name holding the file content and path is the tracked path name in the index. Only the requested entries are output.

2.stage1temp SP stage2temp SP stage3tmp TAB path RS

The second format is what gets used when --stage=all. The three stage temporary fields (stage1temp, stage2temp, stage3temp) list the name of the temporary file if there is a stage entry in the index or . if there is no stage entry. Paths which only have a stage 0 entry will always be omitted from the output.

In both formats RS (the record separator) is newline by default but will be the null byte if -z was passed on the command line. The temporary file names are always safe strings; they will never contain directory separators or whitespace characters. The path field is always relative to the current directory and the temporary file names are always relative to the top level directory.

If the object being copied out to a temporary file is a symbolic link the content of the link will be written to a normal file. It is up to the end-user or the Porcelain to make use of this information.

EXAMPLES

To update and refresh only the files already checked out

$ git checkout-index -n -f -a && git update-index --ignore-missing --refresh

Using git checkout-index to "export an entire tree"

The prefix ability basically makes it trivial to use git checkout-index as an "export as tree" function. Just read the desired tree into the index, and do:

$ git checkout-index --prefix=git-export-dir/ -a

git checkout-index will "export" the index into the specified directory.

The final "/" is important. The exported name is literally just prefixed with the specified string. Contrast this with the following example.

Export files with a prefix

$ git checkout-index --prefix=.merged- Makefile

This will check out the currently cached copy of Makefile into the file .merged-Makefile.
