7 git-checkout-index - Copy files from the cache to the working directory
12 'git-checkout-index' [-u] [-q] [-a] [-f] [-n] [--prefix=<string>]
17 Will copy all files listed from the cache to the working directory
18 (not overwriting existing files).
23 update stat information for the checked out entries in
27 be quiet if files exist or are not in the cache
30 forces overwrite of existing files
33 checks out all files in the cache (will then continue to
34 process listed files).
37 Don't checkout new files, only refresh files already checked
41 When creating files, prepend <string> (usually a directory
42 including a trailing /)
45 Do not interpret any more arguments as options.
47 Note that the order of the flags matters:
49 git-checkout-index -a -f file.c
51 will first check out all files listed in the cache (but not overwrite
52 any old ones), and then force-checkout `file.c` a second time (ie that
53 one *will* overwrite any old contents with the same filename).
55 Also, just doing "git-checkout-index" does nothing. You probably meant
56 "git-checkout-index -a". And if you want to force it, you want
57 "git-checkout-index -f -a".
59 Intuitiveness is not the goal here. Repeatability is. The reason for
60 the "no arguments means no work" thing is that from scripts you are
61 supposed to be able to do things like:
63 find . -name '*.h' -print0 | xargs -0 git-checkout-index -f --
65 which will force all existing `*.h` files to be replaced with their
66 cached copies. If an empty command line implied "all", then this would
67 force-refresh everything in the cache, which was not the point.
69 To update and refresh only the files already checked out:
71 git-checkout-index -n -f -a && git-update-index --ignore-missing --refresh
73 Oh, and the "--" is just a good idea when you know the rest will be
74 filenames. Just so that you wouldn't have a filename of "-a" causing
75 problems (not possible in the above example, but get used to it in
78 The prefix ability basically makes it trivial to use
79 git-checkout-index as an "export as tree" function. Just read the
80 desired tree into the index, and do a
82 git-checkout-index --prefix=git-export-dir/ -a
84 and git-checkout-index will "export" the cache into the specified
87 NOTE The final "/" is important. The exported name is literally just
88 prefixed with the specified string, so you can also do something like
90 git-checkout-index --prefix=.merged- Makefile
92 to check out the currently cached copy of `Makefile` into the file
