7 configuration, which reduces the checkout to a set of paths
8 given by a list of atterns.
14 'git sparse-checkout <subcommand> [options]'
20 Initialize and modify the sparse-checkout configuration, which reduces
21 the checkout to a set of paths given by a list of patterns.
23 THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR, AND THE BEHAVIOR OF OTHER
24 COMMANDS IN THE PRESENCE OF SPARSE-CHECKOUTS, WILL LIKELY CHANGE IN
31 Describe the patterns in the sparse-checkout file.
34 Enable the `core.sparseCheckout` setting. If the
35 sparse-checkout file does not exist, then populate it with
36 patterns that match every file in the root directory and
37 no other directories, then will remove all directories tracked
38 by Git. Add patterns to the sparse-checkout file to
39 repopulate the working directory.
41 To avoid interfering with other worktrees, it first enables the
42 `extensions.worktreeConfig` setting and makes sure to set the
43 `core.sparseCheckout` setting in the worktree-specific config file.
46 Write a set of patterns to the sparse-checkout file, as given as
47 a list of arguments following the 'set' subcommand. Update the
48 working directory to match the new patterns. Enable the
49 core.sparseCheckout config setting if it is not already enabled.
51 When the `--stdin` option is provided, the patterns are read from
52 standard in as a newline-delimited list instead of from the arguments.
54 When `core.sparseCheckoutCone` is enabled, the input list is considered a
55 list of directories instead of sparse-checkout patterns. The command writes
56 patterns to the sparse-checkout file to include all files contained in those
57 directories (recursively) as well as files that are siblings of ancestor
58 directories. The input format matches the output of `git ls-tree --name-only`.
59 This includes interpreting pathnames that begin with a double quote (") as
60 C-style quoted strings.
63 Disable the `core.sparseCheckout` config setting, and restore the
64 working directory to include all files. Leaves the sparse-checkout
65 file intact so a later 'git sparse-checkout init' command may
66 return the working directory to the same state.
71 "Sparse checkout" allows populating the working directory sparsely.
72 It uses the skip-worktree bit (see linkgit:git-update-index[1]) to tell
73 Git whether a file in the working directory is worth looking at. If
74 the skip-worktree bit is set, then the file is ignored in the working
75 directory. Git will not populate the contents of those files, which
76 makes a sparse checkout helpful when working in a repository with many
77 files, but only a few are important to the current user.
79 The `$GIT_DIR/info/sparse-checkout` file is used to define the
80 skip-worktree reference bitmap. When Git updates the working
81 directory, it updates the skip-worktree bits in the index based
82 on this file. The files matching the patterns in the file will
83 appear in the working directory, and the rest will not.
85 To enable the sparse-checkout feature, run `git sparse-checkout init` to
86 initialize a simple sparse-checkout file and enable the `core.sparseCheckout`
87 config setting. Then, run `git sparse-checkout set` to modify the patterns in
88 the sparse-checkout file.
90 To repopulate the working directory with all files, use the
91 `git sparse-checkout disable` command.
97 By default, the sparse-checkout file uses the same syntax as `.gitignore`
100 While `$GIT_DIR/info/sparse-checkout` is usually used to specify what
101 files are included, you can also specify what files are _not_ included,
102 using negative patterns. For example, to remove the file `unwanted`:
113 The full pattern set allows for arbitrary pattern matches and complicated
114 inclusion/exclusion rules. These can result in O(N*M) pattern matches when
115 updating the index, where N is the number of patterns and M is the number
116 of paths in the index. To combat this performance issue, a more restricted
117 pattern set is allowed when `core.sparseCheckoutCone` is enabled.
119 The accepted patterns in the cone pattern set are:
121 1. *Recursive:* All paths inside a directory are included.
123 2. *Parent:* All files immediately inside a directory are included.
125 In addition to the above two patterns, we also expect that all files in the
126 root directory are included. If a recursive pattern is added, then all
127 leading directories are added as parent patterns.
129 By default, when running `git sparse-checkout init`, the root directory is
130 added as a parent pattern. At this point, the sparse-checkout file contains
131 the following patterns:
138 This says "include everything in root, but nothing two levels below root."
140 When in cone mode, the `git sparse-checkout set` subcommand takes a list of
141 directories instead of a list of sparse-checkout patterns. In this mode,
142 the command `git sparse-checkout set A/B/C` sets the directory `A/B/C` as
143 a recursive pattern, the directories `A` and `A/B` are added as parent
144 patterns. The resulting sparse-checkout file is now
156 Here, order matters, so the negative patterns are overridden by the positive
157 patterns that appear lower in the file.
159 If `core.sparseCheckoutCone=true`, then Git will parse the sparse-checkout file
160 expecting patterns of these types. Git will warn if the patterns do not match.
161 If the patterns do match the expected format, then Git will use faster hash-
162 based algorithms to compute inclusion in the sparse-checkout.
164 In the cone mode case, the `git sparse-checkout list` subcommand will list the
165 directories that define the recursive patterns. For the example sparse-checkout
166 file above, the output is as follows:
168 --------------------------
169 $ git sparse-checkout list
171 --------------------------
173 If `core.ignoreCase=true`, then the pattern-matching algorithm will use a
174 case-insensitive check. This corrects for case mismatched filenames in the
175 'git sparse-checkout set' command to reflect the expected cone in the working
182 If your repository contains one or more submodules, then those submodules will
183 appear based on which you initialized with the `git submodule` command. If
184 your sparse-checkout patterns exclude an initialized submodule, then that
185 submodule will still appear in your working directory.
