6 git-checkout-index - Copy files from the index to the working tree
12 'git checkout-index' [-u] [-q] [-a] [-f] [-n] [--prefix=<string>]
13 [--stage=<number>|all]
15 [--ignore-skip-worktree-bits]
21 Will copy all files listed from the index to the working directory
22 (not overwriting existing files).
28 update stat information for the checked out entries in
33 be quiet if files exist or are not in the index
37 forces overwrite of existing files
41 checks out all files in the index except for those with the
42 skip-worktree bit set (see `--ignore-skip-worktree-bits`).
43 Cannot be used together with explicit filenames.
47 Don't checkout new files, only refresh files already checked
51 When creating files, prepend <string> (usually a directory
52 including a trailing /)
54 --stage=<number>|all::
55 Instead of checking out unmerged entries, copy out the
56 files from named stage. <number> must be between 1 and 3.
57 Note: --stage=all automatically implies --temp.
60 Instead of copying the files to the working directory
61 write the content to temporary files. The temporary name
62 associations will be written to stdout.
64 --ignore-skip-worktree-bits::
65 Check out all files, including those with the skip-worktree bit
69 Instead of taking list of paths from the command line,
70 read list of paths from the standard input. Paths are
71 separated by LF (i.e. one path per line) by default.
74 Only meaningful with `--stdin`; paths are separated with
75 NUL character instead of LF.
78 Do not interpret any more arguments as options.
80 The order of the flags used to matter, but not anymore.
82 Just doing `git checkout-index` does nothing. You probably meant
83 `git checkout-index -a`. And if you want to force it, you want
84 `git checkout-index -f -a`.
86 Intuitiveness is not the goal here. Repeatability is. The reason for
87 the "no arguments means no work" behavior is that from scripts you are
88 supposed to be able to do:
91 $ find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
94 which will force all existing `*.h` files to be replaced with their
95 cached copies. If an empty command line implied "all", then this would
96 force-refresh everything in the index, which was not the point. But
97 since 'git checkout-index' accepts --stdin it would be faster to use:
100 $ find . -name '*.h' -print0 | git checkout-index -f -z --stdin
103 The `--` is just a good idea when you know the rest will be filenames;
104 it will prevent problems with a filename of, for example, `-a`.
105 Using `--` is probably a good policy in scripts.
108 Using --temp or --stage=all
109 ---------------------------
110 When `--temp` is used (or implied by `--stage=all`)
111 'git checkout-index' will create a temporary file for each index
112 entry being checked out. The index will not be updated with stat
113 information. These options can be useful if the caller needs all
114 stages of all unmerged entries so that the unmerged files can be
115 processed by an external merge tool.
117 A listing will be written to stdout providing the association of
118 temporary file names to tracked path names. The listing format
121 . tempname TAB path RS
123 The first format is what gets used when `--stage` is omitted or
124 is not `--stage=all`. The field tempname is the temporary file
125 name holding the file content and path is the tracked path name in
126 the index. Only the requested entries are output.
128 . stage1temp SP stage2temp SP stage3tmp TAB path RS
130 The second format is what gets used when `--stage=all`. The three
131 stage temporary fields (stage1temp, stage2temp, stage3temp) list the
132 name of the temporary file if there is a stage entry in the index
133 or `.` if there is no stage entry. Paths which only have a stage 0
134 entry will always be omitted from the output.
136 In both formats RS (the record separator) is newline by default
137 but will be the null byte if -z was passed on the command line.
138 The temporary file names are always safe strings; they will never
139 contain directory separators or whitespace characters. The path
140 field is always relative to the current directory and the temporary
141 file names are always relative to the top level directory.
143 If the object being copied out to a temporary file is a symbolic
144 link the content of the link will be written to a normal file. It is
145 up to the end-user or the Porcelain to make use of this information.
150 To update and refresh only the files already checked out::
153 $ git checkout-index -n -f -a && git update-index --ignore-missing --refresh
156 Using 'git checkout-index' to "export an entire tree"::
157 The prefix ability basically makes it trivial to use
158 'git checkout-index' as an "export as tree" function.
159 Just read the desired tree into the index, and do:
162 $ git checkout-index --prefix=git-export-dir/ -a
165 `git checkout-index` will "export" the index into the specified
168 The final "/" is important. The exported name is literally just
169 prefixed with the specified string. Contrast this with the
172 Export files with a prefix::
175 $ git checkout-index --prefix=.merged- Makefile
178 This will check out the currently cached copy of `Makefile`
179 into the file `.merged-Makefile`.
