git-checkout-index(1) |
|
===================== |
|
|
|
NAME |
|
---- |
|
git-checkout-index - Copy files from the index to the working directory |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
'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`. |
