NAME
|
|
----
|
|
git-checkout-index - Copy files from the index to the working directory
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git-checkout-index' [-u] [-q] [-a] [-f] [-n] [--prefix=<string>]
|
|
[--stage=<number>] [--] <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>::
|
|
Instead of checking out unmerged entries, copy out the
|
|
files from named stage. <number> must be between 1 and 3.
|
|
|
|
--::
|
|
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.
|
|
|
|
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.
|
|
|
|
|
|
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`.
