27 .Op Ar arg ...
28 .Sh DESCRIPTION
29 .Nm
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 .
34 .Pp
35 .Nm
36 is a
37 .Dq distributed
38 version control system because every copy of a repository is writeable.
39 Modifications made to files can be synchronized between repositories
40 at any time.
41 .Pp
42 Files managed by
43 .Nm
44 must be checked out from the repository for modification.
45 Checked out files are stored in a
46 .Em work tree
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
49 .Xr got-worktree 5 .
50 .Pp
51 .Nm
52 provides global and command-specific options.
53 Global options must preceed the command name, and are as follows:
54 .Bl -tag -width tenletters
55 .It Fl h
56 Display usage information and exit immediately.
57 .It Fl V
58 Display program version and exit immediately.
59 .El
60 .Pp
61 The commands for
62 .Nm
63 are as follows:
64 .Bl -tag -width checkout
65 .It Cm init Ar repository-path
66 Create a new empty repository at the specified
67 .Ar repository-path .
68 .Pp
69 After
70 .Cm got init ,
71 the
72 .Cm got import
73 command must be used to populate the empty repository before
74 .Cm got checkout
75 can be used.
76 .It Cm in
77 Short alias for
78 .Cm init .
79 .It Cm import Oo Fl b Ar branch Oc Oo Fl m Ar message Oc Oo Fl r Ar repository-path Oc Oo Fl I Ar pattern Oc Ar directory
80 Create an initial commit in a repository from the file hierarchy
81 within the specified
82 .Ar directory .
83 The created commit will not have any parent commits, i.e. it will be a
84 root commit.
85 Also create a new reference which provides a branch name for the newly
86 created commit.
87 Show the path of each imported file to indicate progress.
88 .Pp
89 The
90 .Cm got import
91 command requires the
92 .Ev GOT_AUTHOR
93 environment variable to be set.
94 .Pp
95 The options for
96 .Cm got import
97 are as follows:
98 .Bl -tag -width Ds
99 .It Fl b Ar branch
100 Create the specified
101 .Ar branch
102 instead of creating the default branch
103 .Dq master .
104 Use of this option is required if the
105 .Dq master
106 branch already exists.
107 .It Fl m Ar message
108 Use the specified log message when creating the new commit.
109 Without the
110 .Fl m
111 option,
112 .Cm got import
113 opens a temporary file in an editor where a log message can be written.
114 .It Fl r Ar repository-path
115 Use the repository at the specified path.
116 If not specified, assume the repository is located at or above the current
117 working directory.
118 .It Fl I Ar pattern
119 Ignore files or directories with a name which matches the specified
120 .Ar pattern .
121 This option may be specified multiple times to build a list of ignore patterns.
122 The
123 .Ar pattern
124 follows the globbing rules documented in
125 .Xr glob 7 .
126 .El
127 .It Cm im
128 Short alias for
129 .Cm import .
130 .It Cm checkout Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Oo Fl p Ar path-prefix Oc Ar repository-path Op Ar work-tree-path
131 Copy files from a repository into a new work tree.
132 If the
133 .Ar work tree path
134 is not specified, either use the last component of
135 .Ar repository path ,
136 or if a
137 .Ar path prefix
138 was specified use the last component of
139 .Ar path prefix .
140 .Pp
141 The options for
142 .Cm got checkout
143 are as follows:
144 .Bl -tag -width Ds
145 .It Fl b Ar branch
146 Check out files from a commit on the specified
147 .Ar branch .
148 If this option is not specified, a branch resolved via the repository's HEAD
149 reference will be used.
150 .It Fl c Ar commit
151 Check out files from the specified
152 .Ar commit
153 on the selected branch.
154 The expected argument is a commit ID SHA1 hash or an existing reference
155 or tag name which will be resolved to a commit ID.
156 An abbreviated hash argument will be expanded to a full SHA1 hash
157 automatically, provided the abbreviation is unique.
158 If this option is not specified, the most recent commit on the selected
159 branch will be used.
160 .It Fl p Ar path-prefix
161 Restrict the work tree to a subset of the repository's tree hierarchy.
162 Only files beneath the specified
163 .Ar path-prefix
164 will be checked out.
165 .El
166 .It Cm co
167 Short alias for
168 .Cm checkout .
169 .It Cm update Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Op Ar path ...
170 Update an existing work tree to a different commit.
171 Show the status of each affected file, using the following status codes:
172 .Bl -column YXZ description
173 .It U Ta file was updated and contained no local changes
174 .It G Ta file was updated and local changes were merged cleanly
175 .It C Ta file was updated and conflicts occurred during merge
176 .It D Ta file was deleted

178 .It \(a~ Ta versioned file is obstructed by a non-regular file
179 .It ! Ta a missing versioned file was restored
180 .El
181 .Pp
182 If no
183 .Ar path
184 is specified, update the entire work tree.
185 Otherwise, restrict the update operation to files at or within the
186 specified paths.
187 Each path is required to exist in the update operation's target commit.
188 Files in the work tree outside specified paths will remain unchanged and
189 will retain their previously recorded base commit.
190 Some
191 .Nm
192 commands may refuse to run while the work tree contains files from
193 multiple base commits.
194 The base commit of such a work tree can be made consistent by running
195 .Cm got update
196 across the entire work tree.
197 Specifying a
198 .Ar path
199 is incompatible with the
200 .Fl b
201 option.
202 .Pp
203 .Cm got update
204 cannot update paths with staged changes.
205 If changes have been staged with
206 .Cm got stage ,
207 these changes must first be comitted with
208 .Cm got commit

219 before updating the work tree.
220 This option requires that all paths in the work tree are updated.
221 .It Fl c Ar commit
222 Update the work tree to the specified
223 .Ar commit .
224 The expected argument is a commit ID SHA1 hash or an existing reference
225 or tag name which will be resolved to a commit ID.
226 An abbreviated hash argument will be expanded to a full SHA1 hash
227 automatically, provided the abbreviation is unique.
228 If this option is not specified, the most recent commit on the work tree's
229 branch will be used.
230 .El
231 .It Cm up
232 Short alias for
233 .Cm update .
234 .It Cm status Op Ar path ...
235 Show the current modification status of files in a work tree,
236 using the following status codes:
237 .Bl -column YXZ description
238 .It M Ta modified file
239 .It A Ta file scheduled for addition in next commit
240 .It D Ta file scheduled for deletion in next commit
241 .It C Ta modified or added file which contains merge conflicts
242 .It ! Ta versioned file was expected on disk but is missing
243 .It \(a~ Ta versioned file is obstructed by a non-regular file
244 .It ? Ta unversioned item not tracked by
245 .Nm
246 .El
247 .Pp
248 If no
249 .Ar path
250 is specified, show modifications in the entire work tree.
251 Otherwise, show modifications at or within the specified paths.
252 .Pp
253 If changes have been staged with
254 .Cm got stage ,
255 staged changes are shown in the second output column, using the following
256 status codes:
257 .Bl -column YXZ description
258 .It M Ta file modification is staged
259 .It A Ta file addition is staged
260 .It D Ta file deletion is staged
261 .El
262 .Pp
263 Changes created on top of staged changes are indicated in the first column:
264 .Bl -column YXZ description
265 .It MM Ta file was modified after earlier changes have been staged
266 .It MA Ta file was modified after having been staged for addition
267 .El
268 .Pp
269 For compatibility with
270 .Xr cvs 1 ,
271 .Cm got status
272 parses
273 .Pa .cvsignore
274 files in each traversed directory and will not display unversioned files
275 which match
276 .Xr glob 7
277 ignore patterns contained in
278 .Pa .cvsignore
279 files.
280 Unlike
281 .Xr cvs 1 ,
282 .Cm got status
283 only supports a single ignore pattern per line.

627 .El
628 .Pp
629 .Cm got commit
630 will refuse to run if certain preconditions are not met.
631 If the work tree's current branch is not in the
632 .Dq refs/heads/
633 reference namespace, new commits may not be created on this branch.
634 Local changes may only be committed if they are based on file content
635 found in the most recent commit on the work tree's branch.
636 If a path is found to be out of date,

1235 .Dl $ cd /var/git/repo
1236 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
1237 .Pp
1238 Alternatively, the following
1239 .Pa fetch
1240 configuration item can be added manually to the Git repository's
1241 .Pa config
1242 file:
1243 .Pp
1244 .Dl [remote "origin"]
1245 .Dl url = ...
1246 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
1247 .Pp
1248 This configuration leaves the local repository's
1249 .Dq refs/heads
1250 namespace free for use by local branches checked out with
1251 .Cm got checkout
1252 and, if needed, created with
1253 .Cm got branch .
1254 .Pp
1255 Branches in the
1256 .Dq remotes/origin
1257 namespace can be updated with incoming changes from the remote
1258 repository with
1259 .Cm git fetch :
1260 .Pp
1261 .Dl $ cd /var/git/repo
1262 .Dl $ git fetch
1263 .Pp
1264 Before outgoing changes on the local
1265 .Dq master
1266 branch can be pushed to the remote repository, the local
1267 .Dq master
1268 branch must be rebased onto the
1269 .Dq origin/master
1270 branch:
1271 .Pp
1272 .Dl $ got update -b origin/master
1273 .Dl $ got rebase master
1274 .Pp
1275 Changes on the local
1276 .Dq master
1277 branch can then be pushed to the remote
1278 repository with
1279 .Cm git push :
1280 .Pp
1281 .Dl $ cd /var/git/repo
1282 .Dl $ git push origin master

1293 is a work-in-progress and many commands remain to be implemented.
1294 At present, the user has to fall back on

1296 to perform many tasks, in particular tasks related to repository
1297 administration and tasks which require a network connection.
