NAME
git-checkout-index - Copy files from the index to the
working tree
SYNOPSIS
git checkout-index [-u] [-q] [-a] [-f] [-n] [--prefix=<string>]
[--stage=<number>|all]
[--temp]
[-z] [--stdin]
[--] [<file>...]
DESCRIPTION
Will copy all files listed from the index to the working
directory (not overwriting existing files).
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. Cannot be used
together with explicit filenames.
-n, --no-create
Don't checkout new files, only refresh files already
checked out.
--prefix=<string>
When creating files, prepend <string> (usually a
directory including a trailing /)
--stage=<number>|all
Instead of checking out unmerged entries, copy out the
files from 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.
--stdin
Instead of taking list of paths from the command line,
read list of paths from the standard input. Paths are

Git Manual GIT-CHECKOUT-INDEX(1)
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.
--
Do not interpret any more arguments as options.
The order of the flags used to matter, but not anymore.
Just doing git checkout-index does nothing. You probably
meant git checkout-index -a. And if you want to force it,
you want git checkout-index -f -a.
Intuitiveness is not the goal here. Repeatability is. The
reason for the "no arguments means no work" behavior is that
from scripts you are supposed to be able to do:
$ find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
which will force all existing *.h files to be replaced with
their cached copies. If an empty command line implied "all",
then this would force-refresh everything in the index, which
was not the point. But since git checkout-index accepts
--stdin it would be faster to use:
$ find . -name '*.h' -print0 | git checkout-index -f -z --stdin
The -- is just a good idea when you know the rest will be
filenames; it will prevent problems with a filename of, for
example, -a. Using -- is probably a good policy in scripts.
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
Git 1.7.9.2 Last change: 02/22/2012 2
Git Manual GIT-CHECKOUT-INDEX(1)
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.
