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.
45 When `--cone` is provided, the `core.sparseCheckoutCone` setting is
46 also set, allowing for better performance with a limited set of
47 patterns (see 'CONE PATTERN SET' below).
50 Write a set of patterns to the sparse-checkout file, as given as
51 a list of arguments following the 'set' subcommand. Update the
52 working directory to match the new patterns. Enable the
53 core.sparseCheckout config setting if it is not already enabled.
55 When the `--stdin` option is provided, the patterns are read from
56 standard in as a newline-delimited list instead of from the arguments.
58 When `core.sparseCheckoutCone` is enabled, the input list is considered a
59 list of directories instead of sparse-checkout patterns. The command writes
60 patterns to the sparse-checkout file to include all files contained in those
61 directories (recursively) as well as files that are siblings of ancestor
62 directories. The input format matches the output of `git ls-tree --name-only`.
63 This includes interpreting pathnames that begin with a double quote (") as
64 C-style quoted strings.
67 Update the sparse-checkout file to include additional patterns.
68 By default, these patterns are read from the command-line arguments,
69 but they can be read from stdin using the `--stdin` option. When
70 `core.sparseCheckoutCone` is enabled, the given patterns are interpreted
71 as directory names as in the 'set' subcommand.
74 Disable the `core.sparseCheckout` config setting, and restore the
75 working directory to include all files. Leaves the sparse-checkout
76 file intact so a later 'git sparse-checkout init' command may
77 return the working directory to the same state.
82 "Sparse checkout" allows populating the working directory sparsely.
83 It uses the skip-worktree bit (see linkgit:git-update-index[1]) to tell
84 Git whether a file in the working directory is worth looking at. If
85 the skip-worktree bit is set, then the file is ignored in the working
86 directory. Git will not populate the contents of those files, which
87 makes a sparse checkout helpful when working in a repository with many
88 files, but only a few are important to the current user.
90 The `$GIT_DIR/info/sparse-checkout` file is used to define the
91 skip-worktree reference bitmap. When Git updates the working
92 directory, it updates the skip-worktree bits in the index based
93 on this file. The files matching the patterns in the file will
94 appear in the working directory, and the rest will not.
96 To enable the sparse-checkout feature, run `git sparse-checkout init` to
97 initialize a simple sparse-checkout file and enable the `core.sparseCheckout`
98 config setting. Then, run `git sparse-checkout set` to modify the patterns in
99 the sparse-checkout file.
101 To repopulate the working directory with all files, use the
102 `git sparse-checkout disable` command.
108 By default, the sparse-checkout file uses the same syntax as `.gitignore`
111 While `$GIT_DIR/info/sparse-checkout` is usually used to specify what
112 files are included, you can also specify what files are _not_ included,
113 using negative patterns. For example, to remove the file `unwanted`:
124 The full pattern set allows for arbitrary pattern matches and complicated
125 inclusion/exclusion rules. These can result in O(N*M) pattern matches when
126 updating the index, where N is the number of patterns and M is the number
127 of paths in the index. To combat this performance issue, a more restricted
128 pattern set is allowed when `core.sparseCheckoutCone` is enabled.
130 The accepted patterns in the cone pattern set are:
132 1. *Recursive:* All paths inside a directory are included.
134 2. *Parent:* All files immediately inside a directory are included.
136 In addition to the above two patterns, we also expect that all files in the
137 root directory are included. If a recursive pattern is added, then all
138 leading directories are added as parent patterns.
140 By default, when running `git sparse-checkout init`, the root directory is
141 added as a parent pattern. At this point, the sparse-checkout file contains
142 the following patterns:
149 This says "include everything in root, but nothing two levels below root."
151 When in cone mode, the `git sparse-checkout set` subcommand takes a list of
152 directories instead of a list of sparse-checkout patterns. In this mode,
153 the command `git sparse-checkout set A/B/C` sets the directory `A/B/C` as
154 a recursive pattern, the directories `A` and `A/B` are added as parent
155 patterns. The resulting sparse-checkout file is now
167 Here, order matters, so the negative patterns are overridden by the positive
168 patterns that appear lower in the file.
170 If `core.sparseCheckoutCone=true`, then Git will parse the sparse-checkout file
171 expecting patterns of these types. Git will warn if the patterns do not match.
172 If the patterns do match the expected format, then Git will use faster hash-
173 based algorithms to compute inclusion in the sparse-checkout.
175 In the cone mode case, the `git sparse-checkout list` subcommand will list the
176 directories that define the recursive patterns. For the example sparse-checkout
177 file above, the output is as follows:
179 --------------------------
180 $ git sparse-checkout list
182 --------------------------
184 If `core.ignoreCase=true`, then the pattern-matching algorithm will use a
185 case-insensitive check. This corrects for case mismatched filenames in the
186 'git sparse-checkout set' command to reflect the expected cone in the working
193 If your repository contains one or more submodules, then those submodules will
194 appear based on which you initialized with the `git submodule` command. If
195 your sparse-checkout patterns exclude an initialized submodule, then that
196 submodule will still appear in your working directory.
