22 git-checkout-index \- Copy files from the index to the working directory
26 git\-checkout\-index [\-u] [\-q] [\-a] [\-f] [\-n] [\-\-prefix=<string>] [\-\-stage=<number>] [\-\-] <file>...
31 Will copy all files listed from the index to the working directory (not overwriting existing files)\&.
37 update stat information for the checked out entries in the index file\&.
41 be quiet if files exist or are not in the index
45 forces overwrite of existing files
49 checks out all files in the index\&. Cannot be used together with explicit filenames\&.
53 Don't checkout new files, only refresh files already checked out\&.
57 When creating files, prepend <string> (usually a directory including a trailing /)
61 Instead of checking out unmerged entries, copy out the files from named stage\&. <number> must be between 1 and 3\&.
65 Do not interpret any more arguments as options\&.
68 The order of the flags used to matter, but not anymore\&.
71 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\&.
74 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:
77 $ find \&. \-name '*\&.h' \-print0 | xargs \-0 git\-checkout\-index \-f \-\-
79 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\&.
82 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\&.
87 To update and refresh only the files already checked out
90 $ git\-checkout\-index \-n \-f \-a && git\-update\-index \-\-ignore\-missing \-\-refresh
92 Using git\-checkout\-index to "export an entire tree"
93 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:
97 $ git\-checkout\-index \-\-prefix=git\-export\-dir/ \-agit\-checkout\-index will "export" the index into the specified directory\&.
99 The final "/" is important\&. The exported name is literally just prefixed with the specified string\&. Contrast this with the following example\&.
102 Export files with a prefix
105 $ git\-checkout\-index \-\-prefix=\&.merged\- MakefileThis will check out the currently cached copy of Makefile into the file \&.merged\-Makefile\&.
