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 precede 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
177 .It A Ta new file was added
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 committed with
208 .Cm got commit
209 or unstaged with
210 .Cm got unstage .
211 .Pp
212 The options for
213 .Cm got update
214 are as follows:
215 .Bl -tag -width Ds
216 .It Fl b Ar branch
217 Switch the work tree's branch reference to the specified
218 .Ar branch
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.
284 .It Cm st
285 Short alias for

299 .Ar commit .
300 The expected argument is a commit ID SHA1 hash or an existing reference
301 or tag name which will be resolved to a commit ID.
302 An abbreviated hash argument will be expanded to a full SHA1 hash
303 automatically, provided the abbreviation is unique.
304 If this option is not specified, default to the work tree's current branch
305 if invoked in a work tree, or to the repository's HEAD reference.
306 .It Fl C Ar number
307 Set the number of context lines shown in diffs with
308 .Fl p .
309 By default, 3 lines of context are shown.
310 .It Fl f
311 Restrict history traversal to the first parent of each commit.
312 This shows the linear history of the current branch only.
313 Merge commits which affected the current branch will be shown but
314 individual commits which originated on other branches will be omitted.
315 .It Fl l Ar N
316 Limit history traversal to a given number of commits.
317 If this option is not specified, a default limit value of zero is used,
318 which is treated as an unbounded limit.
319 The
320 .Ev GOT_LOG_DEFAULT_LIMIT
321 environment variable may be set to change this default value.
322 .It Fl p
323 Display the patch of modifications made in each commit.

335 If a
336 .Ar path
337 is specified, only show changes within this path.
338 .Pp
339 If two arguments are provided, treat each argument as a reference, a tag
340 name, or an object ID SHA1 hash, and display differences between the
341 corresponding objects.
342 Both objects must be of the same type (blobs, trees, or commits).
343 An abbreviated hash argument will be expanded to a full SHA1 hash
344 automatically, provided the abbreviation is unique.
345 .Pp
346 The options for
347 .Cm got diff
348 are as follows:

597 There is no way to bring discarded changes back after
598 .Cm got revert !
599 .Pp
600 If a file was added with
601 .Cm got add
602 it will become an unversioned file again.
603 If a file was deleted with
604 .Cm got remove
605 it will be restored.
606 .Pp
607 The options for
608 .Cm got revert
609 are as follows:
610 .Bl -tag -width Ds
611 .It Fl p
612 Instead of reverting all changes in files, interactively select or reject
613 changes to revert based on

1234 .Pp
1235 Switch an existing work tree to the branch
1236 .Dq unified-buffer-cache .
1237 Local changes in the work tree will be preserved and merged if necessary:
1238 .Pp
1239 .Dl $ got update -b unified-buffer-cache
1240 .Pp
1241 Create a new commit from local changes in a work tree directory.
1242 This new commit will become the head commit of the work tree's current branch:
1243 .Pp
1244 .Dl $ got commit
1245 .Pp
1246 In a work tree or a git repository directory, view changes committed in
1247 the 3 most recent commits to the work tree's branch, or the branch resolved
1248 via the repository's HEAD reference, respectively:
1249 .Pp
1250 .Dl $ got log -p -l 3 -f
1251 .Pp
1252 Add new files and remove obsolete files in a work tree directory:
1253 .Pp
1254 .Dl $ got add sys/uvm/uvm_ubc.c
1255 .Dl $ got remove sys/uvm/uvm_vnode.c
1256 .Pp
1257 Create a new commit from local changes in a work tree directory
1258 with a pre-defined log message.
1259 .Pp
1260 .Dl $ got commit -m 'unify the buffer cache'
1261 .Pp
1262 Update any work tree checked out from the
1263 .Dq unified-buffer-cache
1264 branch to the latest commit on this branch:
1265 .Pp
1266 .Dl $ got update
1267 .Pp
1268 Roll file content on the unified-buffer-cache branch back by one commit,
1269 and then fetch the rolled-back change into the work tree as a local change
1270 to be amended and perhaps committed again:
1271 .Pp
1272 .Dl $ got backout unified-buffer-cache
1273 .Dl $ got commit -m 'roll back previous'
1274 .Dl $ # now back out the previous backout :-)
1275 .Dl $ got backout unified-buffer-cache
1276 .Pp
1277 Fetch new upstream commits into the local repository's master branch.
1278 This step currently requires
1279 .Xr git 1 :
1280 .Pp
1281 .Dl $ cd /var/git/src.git
1282 .Dl $ git fetch origin master:master
1283 .Pp
1284 Rebase the
1285 .Dq unified-buffer-cache
1286 branch on top of the new head commit of the
1287 .Dq master
1288 branch.
1289 .Pp
1290 .Dl $ got update -b master
1291 .Dl $ got rebase unified-buffer-cache
1292 .Pp
1293 Create a patch from all changes on the unified-buffer-cache branch.
1294 The patch can be mailed out for review and applied to
1295 .Ox Ns 's
1296 CVS tree:
1297 .Pp
1298 .Dl $ got diff master unified-buffer-cache > /tmp/ubc.diff
1299 .Pp
1300 Edit the entire commit history of the
1301 .Dq unified-buffer-cache
1302 branch:
1303 .Pp
1304 .Dl $ got update -b unified-buffer-cache
1305 .Dl $ got update -c master
1306 .Dl $ got histedit
1307 .Pp
1308 Additional steps are necessary if local changes need to be pushed back
1309 to the remote repository, which currently requires
1310 .Cm git fetch
1311 and
1312 .Cm git push .
1313 Before working against existing branches in a repository cloned with
1314 .Dq git clone --bare ,
1315 a Git
1316 .Dq refspec
1317 must be configured to map all references in the remote repository
1318 into the
1319 .Dq refs/remotes
1320 namespace of the local repository.
1321 This can achieved by setting Git's
1322 .Pa remote.origin.fetch
1323 configuration variable to the value
1324 .Dq +refs/heads/*:refs/remotes/origin/*
1325 with the
1326 .Cm git config
1327 command:
1328 .Pp
1329 .Dl $ cd /var/git/repo
1330 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
1331 .Pp
1332 Alternatively, the following
1333 .Pa fetch
1334 configuration item can be added manually to the Git repository's
1335 .Pa config
1336 file:
1337 .Pp
1338 .Dl [remote "origin"]
1339 .Dl url = ...
1340 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
1341 .Pp
1342 This configuration leaves the local repository's
1343 .Dq refs/heads
1344 namespace free for use by local branches checked out with
1345 .Cm got checkout
1346 and, if needed, created with
1347 .Cm got branch .
1348 .Pp
1349 Branches in the
1350 .Dq remotes/origin
1351 namespace can be updated with incoming changes from the remote
1352 repository with
1353 .Cm git fetch :
1354 .Pp
1355 .Dl $ cd /var/git/repo
1356 .Dl $ git fetch
1357 .Pp
1358 Before outgoing changes on the local
1359 .Dq master
1360 branch can be pushed to the remote repository, the local
1361 .Dq master
1362 branch must be rebased onto the
1363 .Dq origin/master
1364 branch:
1365 .Pp
1366 .Dl $ got update -b origin/master
1367 .Dl $ got rebase master
1368 .Pp
1369 Changes on the local
1370 .Dq master
1371 branch can then be pushed to the remote
1372 repository with
1373 .Cm git push :
1374 .Pp
1375 .Dl $ cd /var/git/repo
1376 .Dl $ git push origin master
