git-checkout-cache(1) |
|
===================== |
|
v0.1, May 2005 |
|
|
|
NAME |
|
---- |
|
git-checkout-cache - Copy files from the cache to the working directory |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
'git-checkout-cache' [-u] [-q] [-a] [-f] [-n] [--prefix=<string>] |
|
[--] <file>... |
|
|
|
DESCRIPTION |
|
----------- |
|
Will copy all files listed from the cache to the working directory |
|
(not overwriting existing files). |
|
|
|
OPTIONS |
|
------- |
|
-u:: |
|
update stat information for the checked out entries in |
|
the cache file. |
|
|
|
-q:: |
|
be quiet if files exist or are not in the cache |
|
|
|
-f:: |
|
forces overwrite of existing files |
|
|
|
-a:: |
|
checks out all files in the cache (will then continue to |
|
process listed files). |
|
|
|
-n:: |
|
Don't checkout new files, only refresh files already checked |
|
out. |
|
|
|
--prefix=<string>:: |
|
When creating files, prepend <string> (usually a directory |
|
including a trailing /) |
|
|
|
--:: |
|
Do not interpret any more arguments as options. |
|
|
|
Note that the order of the flags matters: |
|
|
|
git-checkout-cache -a -f file.c |
|
|
|
will first check out all files listed in the cache (but not overwrite |
|
any old ones), and then force-checkout `file.c` a second time (ie that |
|
one *will* overwrite any old contents with the same filename). |
|
|
|
Also, just doing "git-checkout-cache" does nothing. You probably meant |
|
"git-checkout-cache -a". And if you want to force it, you want |
|
"git-checkout-cache -f -a". |
|
|
|
Intuitiveness is not the goal here. Repeatability is. The reason for |
|
the "no arguments means no work" thing is that from scripts you are |
|
supposed to be able to do things like: |
|
|
|
find . -name '*.h' -print0 | xargs -0 git-checkout-cache -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 cache, which was not the point. |
|
|
|
To update and refresh only the files already checked out: |
|
|
|
git-checkout-cache -n -f -a && git-update-cache --ignore-missing --refresh |
|
|
|
Oh, and the "--" is just a good idea when you know the rest will be |
|
filenames. Just so that you wouldn't have a filename of "-a" causing |
|
problems (not possible in the above example, but get used to it in |
|
scripting!). |
|
|
|
The prefix ability basically makes it trivial to use |
|
git-checkout-cache as an "export as tree" function. Just read the |
|
desired tree into the index, and do a |
|
|
|
git-checkout-cache --prefix=git-export-dir/ -a |
|
|
|
and git-checkout-cache will "export" the cache into the specified |
|
directory. |
|
|
|
NOTE The final "/" is important. The exported name is literally just |
|
prefixed with the specified string, so you can also do something like |
|
|
|
git-checkout-cache --prefix=.merged- Makefile |
|
|
|
to check out the currently cached copy of `Makefile` into the file |
|
`.merged-Makefile` |
