22 .Nd version control system
30 is a version control system which stores the history of tracked files
31 in a Git repository, as used by the Git version control system.
32 This repository format is described in
33 .Xr git-repository 5 .
38 version control system because every copy of a repository is writeable.
39 Modifications made to files can be synchronized between repositories
44 must be checked out from the repository for modification.
45 Checked out files are stored in a
47 which can be placed at an arbitrary directory in the filesystem hierarchy.
48 The on-disk format of this work tree is described in
52 provides global and command-specific options.
53 Global options must preceed the command name, and are as follows:
54 .Bl -tag -width tenletters

85 Only files beneath the specified
89 .It Cm update [ Fl c Ar commit ] [ work-tree-path ]
90 Update an existing work tree to another commit on the current branch.
91 By default, the latest commit on the current branch is assumed.
92 Show the status of each affected file, using the following status codes:

117 .It Cm status [ Ar path ]
118 Show the current modification status of files in a work tree,
119 using the following status codes:
120 .Bl -column YXZ description

154 Restrict history traversal to the first parent of each commit.
155 This shows the linear history of the current branch only.
156 Merge commits which affected the current branch will be shown but
157 individual commits which originated on other branches will be omitted.
159 Limit history traversal to a given number of commits.

172 uncommitted changes in the work tree.
175 is specified, only show changes within this path.
177 If two arguments are provided, treat each argument as a SHA1 hash which
178 corresponds to an object in the repository, and display differences
179 between these objects.
180 Both objects must be of the same type (blobs, trees, or commits).
187 Set the number of context lines shown in the diff.

285 Remove a versioned file from a work tree and schedule it for deletion
286 from the repository in the next commit.
