=======================
NAME
----
git-sparse-checkout - Initialize and modify the sparse-checkout
configuration, which reduces the checkout to a set of directories
given by a list of prefixes.
SYNOPSIS
--------
[verse]
'git sparse-checkout <subcommand> [options]'
DESCRIPTION
-----------
Initialize and modify the sparse-checkout configuration, which reduces
the checkout to a set of directories given by a list of prefixes.
COMMANDS
--------
'list'::
Provide a list of the contents in the sparse-checkout file.
'init'::
Enable the `core.sparseCheckout` setting. If the
sparse-checkout file does not exist, then populate it with
patterns that match every file in the root directory and
no other directories, then will remove all directories tracked
by Git. Add patterns to the sparse-checkout file to
repopulate the working directory.
'set'::
Write a set of patterns to the sparse-checkout file, as given as
a list of arguments following the 'set' subcommand. Update the
working directory to match the new patterns.
SPARSE CHECKOUT
----------------
"Sparse checkout" allows populating the working directory sparsely.
It uses the skip-worktree bit (see linkgit:git-update-index[1]) to tell
Git whether a file in the working directory is worth looking at. If
the skip-worktree bit is set, then the file is ignored in the working
directory. Git will not populate the contents of those files, which
makes a sparse checkout helpful when working in a repository with many
files, but only a few are important to the current user.
The `$GIT_DIR/info/sparse-checkout` file is used to define the
skip-worktree reference bitmap. When Git updates the working
directory, it resets the skip-worktree bit in the index based on this
file. If an entry
matches a pattern in this file, skip-worktree will not be set on
that entry. Otherwise, skip-worktree will be set.
Then it compares the new skip-worktree value with the previous one. If
skip-worktree turns from set to unset, it will add the corresponding
file back. If it turns from unset to set, that file will be removed.
## FULL PATTERN SET
By default, the sparse-checkout file uses the same syntax as `.gitignore`
files.
While `$GIT_DIR/info/sparse-checkout` is usually used to specify what
files are included, you can also specify what files are _not_ included,
using negative patterns. For example, to remove the file `unwanted`:
----------------
/*
!unwanted
----------------
Another tricky thing is fully repopulating the working directory when you
no longer want sparse checkout. You cannot just disable "sparse
checkout" because skip-worktree bits are still in the index and your working
directory is still sparsely populated. You should re-populate the working
directory with the `$GIT_DIR/info/sparse-checkout` file content as
follows:
----------------
/*
----------------
Then you can disable sparse checkout. Sparse checkout support in 'git
read-tree' and similar commands is disabled by default. You need to
set `core.sparseCheckout` to `true` in order to have sparse checkout
support.
