25 .Ar command
26 .Op Fl h
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 unless Git's
95 .Dv user.name
96 and
97 .Dv user.email
98 configuration settings can be obtained from the repository's
99 .Pa .git/config
100 file or from Git's global
101 .Pa ~/.gitconfig
102 configuration file.
103 .Pp
104 The options for
105 .Cm got import
106 are as follows:
107 .Bl -tag -width Ds
108 .It Fl b Ar branch
109 Create the specified
110 .Ar branch
111 instead of creating the default branch
112 .Dq main .
113 Use of this option is required if the
114 .Dq main
115 branch already exists.
116 .It Fl m Ar message
117 Use the specified log message when creating the new commit.
118 Without the
119 .Fl m
120 option,
121 .Cm got import
122 opens a temporary file in an editor where a log message can be written.
123 .It Fl r Ar repository-path
124 Use the repository at the specified path.
125 If not specified, assume the repository is located at or above the current
126 working directory.
127 .It Fl I Ar pattern
128 Ignore files or directories with a name which matches the specified
129 .Ar pattern .
130 This option may be specified multiple times to build a list of ignore patterns.
131 The
132 .Ar pattern
133 follows the globbing rules documented in
134 .Xr glob 7 .
135 .El
136 .It Cm im
137 Short alias for
138 .Cm import .
139 .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
140 Copy files from a repository into a new work tree.
141 If the
142 .Ar work tree path
143 is not specified, either use the last component of
144 .Ar repository path ,
145 or if a
146 .Ar path prefix
147 was specified use the last component of
148 .Ar path prefix .
149 .Pp
150 The options for
151 .Cm got checkout
152 are as follows:
153 .Bl -tag -width Ds
154 .It Fl b Ar branch
155 Check out files from a commit on the specified
156 .Ar branch .
157 If this option is not specified, a branch resolved via the repository's HEAD
158 reference will be used.
159 .It Fl c Ar commit
160 Check out files from the specified
161 .Ar commit
162 on the selected branch.
163 The expected argument is a commit ID SHA1 hash or an existing reference
164 or tag name which will be resolved to a commit ID.
165 An abbreviated hash argument will be expanded to a full SHA1 hash
166 automatically, provided the abbreviation is unique.
167 If this option is not specified, the most recent commit on the selected
168 branch will be used.
169 .It Fl p Ar path-prefix
170 Restrict the work tree to a subset of the repository's tree hierarchy.
171 Only files beneath the specified
172 .Ar path-prefix
173 will be checked out.
174 .El
175 .It Cm co
176 Short alias for
177 .Cm checkout .
178 .It Cm update Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Op Ar path ...
179 Update an existing work tree to a different commit.
180 Show the status of each affected file, using the following status codes:
181 .Bl -column YXZ description
182 .It U Ta file was updated and contained no local changes
183 .It G Ta file was updated and local changes were merged cleanly
184 .It C Ta file was updated and conflicts occurred during merge
185 .It D Ta file was deleted
186 .It A Ta new file was added
187 .It \(a~ Ta versioned file is obstructed by a non-regular file
188 .It ! Ta a missing versioned file was restored
189 .El
190 .Pp
191 If no
192 .Ar path
193 is specified, update the entire work tree.
194 Otherwise, restrict the update operation to files at or within the
195 specified paths.
196 Each path is required to exist in the update operation's target commit.
197 Files in the work tree outside specified paths will remain unchanged and
198 will retain their previously recorded base commit.
199 Some
200 .Nm
201 commands may refuse to run while the work tree contains files from
202 multiple base commits.
203 The base commit of such a work tree can be made consistent by running
204 .Cm got update
205 across the entire work tree.
206 Specifying a
207 .Ar path
208 is incompatible with the
209 .Fl b
210 option.
211 .Pp
212 .Cm got update
213 cannot update paths with staged changes.
214 If changes have been staged with
215 .Cm got stage ,
216 these changes must first be committed with
217 .Cm got commit
218 or unstaged with
219 .Cm got unstage .
220 .Pp
221 The options for
222 .Cm got update
223 are as follows:
224 .Bl -tag -width Ds
225 .It Fl b Ar branch
226 Switch the work tree's branch reference to the specified
227 .Ar branch
228 before updating the work tree.
229 This option requires that all paths in the work tree are updated.
230 .It Fl c Ar commit
231 Update the work tree to the specified
232 .Ar commit .
233 The expected argument is a commit ID SHA1 hash or an existing reference
234 or tag name which will be resolved to a commit ID.
235 An abbreviated hash argument will be expanded to a full SHA1 hash
236 automatically, provided the abbreviation is unique.
237 If this option is not specified, the most recent commit on the work tree's
238 branch will be used.
239 .El
240 .It Cm up
241 Short alias for
242 .Cm update .
243 .It Cm status Op Ar path ...
244 Show the current modification status of files in a work tree,
245 using the following status codes:
246 .Bl -column YXZ description
247 .It M Ta modified file
248 .It A Ta file scheduled for addition in next commit
249 .It D Ta file scheduled for deletion in next commit
250 .It C Ta modified or added file which contains merge conflicts
251 .It ! Ta versioned file was expected on disk but is missing
252 .It \(a~ Ta versioned file is obstructed by a non-regular file
253 .It ? Ta unversioned item not tracked by
254 .Nm
255 .It m Ta modified file modes (executable bit only)
256 .It N Ta non-existent
257 .Ar path
258 specified on the command line
259 .El
260 .Pp
261 If no
262 .Ar path
263 is specified, show modifications in the entire work tree.
264 Otherwise, show modifications at or within the specified paths.
265 .Pp
266 If changes have been staged with
267 .Cm got stage ,
268 staged changes are shown in the second output column, using the following
269 status codes:
270 .Bl -column YXZ description
271 .It M Ta file modification is staged
272 .It A Ta file addition is staged
273 .It D Ta file deletion is staged
274 .El
275 .Pp
276 Changes created on top of staged changes are indicated in the first column:
277 .Bl -column YXZ description
278 .It MM Ta file was modified after earlier changes have been staged
279 .It MA Ta file was modified after having been staged for addition
280 .El
281 .Pp
282 For compatibility with
283 .Xr cvs 1
284 and
285 .Xr git 1 ,
286 .Cm got status
287 reads
288 .Xr glob 7
289 patterns from
290 .Pa .cvsignore
291 and
292 .Pa .gitignore
293 files in each traversed directory and will not display unversioned files
294 which match these patterns.
295 As an extension to
296 .Xr glob 7
297 matching rules,
298 .Cm got status
299 supports consecutive asterisks,
300 .Dq ** ,
301 which will match an arbitrary amount of directories.
302 Unlike
303 .Xr cvs 1 ,
304 .Cm got status
305 only supports a single ignore pattern per line.
306 Unlike
307 .Xr git 1 ,
308 .Cm got status
309 does not support negated ignore patterns prefixed with
310 .Dq \&! ,
311 and gives no special significance to the location of path component separators,
312 .Dq / ,
313 in a pattern.
314 .It Cm st
315 Short alias for
316 .Cm status .
317 .It Cm log Oo Fl c Ar commit Oc Oo Fl C Ar number Oc Oo Fl f Oc Oo Fl l Ar N Oc Oo Fl p Oc Oo Fl s Ar search-pattern Oc Oo Fl r Ar repository-path Oc Op Ar path
318 Display history of a repository.
319 If a
320 .Ar path
321 is specified, show only commits which modified this path.
322 .Pp
323 The options for
324 .Cm got log
325 are as follows:
326 .Bl -tag -width Ds
327 .It Fl c Ar commit
328 Start traversing history at the specified
329 .Ar commit .
330 The expected argument is a commit ID SHA1 hash or an existing reference
331 or tag name which will be resolved to a commit ID.
332 An abbreviated hash argument will be expanded to a full SHA1 hash
333 automatically, provided the abbreviation is unique.
334 If this option is not specified, default to the work tree's current branch
335 if invoked in a work tree, or to the repository's HEAD reference.
336 .It Fl C Ar number
337 Set the number of context lines shown in diffs with
338 .Fl p .
339 By default, 3 lines of context are shown.
340 .It Fl f
341 Restrict history traversal to the first parent of each commit.
342 This shows the linear history of the current branch only.
343 Merge commits which affected the current branch will be shown but
344 individual commits which originated on other branches will be omitted.
345 .It Fl l Ar N
346 Limit history traversal to a given number of commits.
347 If this option is not specified, a default limit value of zero is used,
348 which is treated as an unbounded limit.
349 The
350 .Ev GOT_LOG_DEFAULT_LIMIT
351 environment variable may be set to change this default value.
352 .It Fl p
353 Display the patch of modifications made in each commit.
354 If a
355 .Ar path
356 is specified, only show the patch of modifications at or within this path.
357 .It Fl s Ar search-pattern
358 If specified, show only commits with a log message matched by the extended
359 regular expression
360 .Ar search-pattern .
361 Regular expression syntax is documented in
362 .Xr re_format 7 .
363 .It Fl r Ar repository-path
364 Use the repository at the specified path.
365 If not specified, assume the repository is located at or above the current
366 working directory.
367 If this directory is a
368 .Nm
369 work tree, use the repository path associated with this work tree.
370 .El
371 .It Cm diff Oo Fl C Ar number Oc Oo Fl r Ar repository-path Oc Oo Fl s Oc Oo Fl w Oc Op Ar object1 Ar object2 | Ar path
372 When invoked within a work tree with less than two arguments, display
373 uncommitted changes in the work tree.
374 If a
375 .Ar path
376 is specified, only show changes within this path.
377 .Pp
378 If two arguments are provided, treat each argument as a reference, a tag
379 name, or an object ID SHA1 hash, and display differences between the
380 corresponding objects.
381 Both objects must be of the same type (blobs, trees, or commits).
382 An abbreviated hash argument will be expanded to a full SHA1 hash
383 automatically, provided the abbreviation is unique.
384 .Pp
385 The options for
386 .Cm got diff
387 are as follows:
388 .Bl -tag -width Ds
389 .It Fl C Ar number
390 Set the number of context lines shown in the diff.
391 By default, 3 lines of context are shown.
392 .It Fl r Ar repository-path
393 Use the repository at the specified path.
394 If not specified, assume the repository is located at or above the current
395 working directory.
396 If this directory is a
397 .Nm
398 work tree, use the repository path associated with this work tree.
399 .It Fl s
400 Show changes staged with
401 .Cm got stage
402 instead of showing local changes.
403 This option is only valid when
404 .Cm got diff
405 is invoked in a work tree.
406 .It Fl w
407 Ignore whitespace-only changes.
408 .El
409 .It Cm di
410 Short alias for

413 Display line-by-line history of a file at the specified path.
414 .Pp
415 The options for
416 .Cm got blame
417 are as follows:
418 .Bl -tag -width Ds
419 .It Fl c Ar commit
420 Start traversing history at the specified
421 .Ar commit .
422 The expected argument is a commit ID SHA1 hash or an existing reference
423 or tag name which will be resolved to a commit ID.
424 An abbreviated hash argument will be expanded to a full SHA1 hash
425 automatically, provided the abbreviation is unique.
426 .It Fl r Ar repository-path
427 Use the repository at the specified path.
428 If not specified, assume the repository is located at or above the current
429 working directory.
430 If this directory is a
431 .Nm
432 work tree, use the repository path associated with this work tree.
433 .El
434 .It Cm bl
435 Short alias for
436 .Cm blame .
437 .It Cm tree Oo Fl c Ar commit Oc Oo Fl r Ar repository-path Oc Oo Fl i Oc Oo Fl R Oc Op Ar path
438 Display a listing of files and directories at the specified
439 directory path in the repository.
440 Entries shown in this listing may carry one of the following trailing
441 annotations:
442 .Bl -column YXZ description
443 .It @ Ta entry is a symbolic link
444 .It / Ta entry is a directory
445 .It * Ta entry is an executable file
446 .It $ Ta entry is a Git submodule
447 .El
448 .Pp
449 If no
450 .Ar path
451 is specified, list the repository path corresponding to the current
452 directory of the work tree, or the root directory of the repository
453 if there is no work tree.
454 .Pp
455 The options for
456 .Cm got tree
457 are as follows:
458 .Bl -tag -width Ds
459 .It Fl c Ar commit
460 List files and directories as they appear in the specified
461 .Ar commit .
462 The expected argument is a commit ID SHA1 hash or an existing reference
463 or tag name which will be resolved to a commit ID.
464 An abbreviated hash argument will be expanded to a full SHA1 hash
465 automatically, provided the abbreviation is unique.
466 .It Fl r Ar repository-path
467 Use the repository at the specified path.
468 If not specified, assume the repository is located at or above the current
469 working directory.
470 If this directory is a
471 .Nm
472 work tree, use the repository path associated with this work tree.
473 .It Fl i
474 Show object IDs of files (blob objects) and directories (tree objects).
475 .It Fl R
476 Recurse into sub-directories in the repository.
477 .El

479 Short alias for
480 .Cm tree .
481 .It Cm ref Oo Fl r Ar repository-path Oc Oo Fl l Oc Oo Fl d Ar name Oc Oo Fl s Oc Op Ar name Ar target
482 Manage references in a repository.
483 .Pp
484 If no options are passed, expect two arguments and attempt to create,
485 or update, the reference with the given
486 .Ar name ,
487 and make it point at the given
488 .Ar target .
489 The name must be an absolute reference name, i.e. it must begin with
490 .Dq refs/ .
491 The target may be an object ID SHA1 hash or an existing reference which
492 will be resolved to an object ID.
493 An abbreviated hash argument will be expanded to a full SHA1 hash
494 automatically, provided the abbreviation is unique.
495 .Pp
496 The options for
497 .Cm got ref
498 are as follows:
499 .Bl -tag -width Ds
500 .It Fl r Ar repository-path
501 Use the repository at the specified path.
502 If not specified, assume the repository is located at or above the current
503 working directory.
504 If this directory is a
505 .Nm
506 work tree, use the repository path associated with this work tree.
507 .It Fl l
508 List all existing references in the repository.
509 .It Fl d Ar name
510 Delete the reference with the specified name from the repository.
511 .It Fl s
512 Create a symbolic reference pointing at the specified
513 .Ar target ,
514 which must be an existing reference.
515 Care should be taken not to create loops between references when
516 this option is used.
517 .El
518 .It Cm branch Oo Fl c Ar commit Oc Oo Fl r Ar repository-path Oc Oo Fl l Oc Oo Fl d Ar name Oc Op Ar name
519 Manage branches in a repository.
520 .Pp
521 Branches are managed via references which live in the
522 .Dq refs/heads/
523 reference namespace.
524 The
525 .Cm got branch
526 command operates on references in this namespace only.
527 .Pp
528 If invoked in a work tree without any arguments, print the name of the
529 work tree's current branch.
530 If a
531 .Ar name
532 argument is passed, attempt to create a branch reference with the given name.
533 By default the new branch reference will point at the latest commit on the
534 work tree's current branch if invoked in a work tree, and otherwise to a commit
535 resolved via the repository's HEAD reference.
536 .Pp
537 The options for
538 .Cm got branch
539 are as follows:
540 .Bl -tag -width Ds
541 .It Fl c Ar commit
542 Make a newly created branch reference point at the specified
543 .Ar commit .
544 The expected
545 .Ar commit
546 argument is a commit ID SHA1 hash or an existing reference
547 or tag name which will be resolved to a commit ID.
548 .It Fl r Ar repository-path
549 Use the repository at the specified path.
550 If not specified, assume the repository is located at or above the current
551 working directory.
552 If this directory is a
553 .Nm
554 work tree, use the repository path associated with this work tree.
555 .It Fl l
556 List all existing branches in the repository.
557 If invoked in a work tree, the work tree's current branch is shown
558 with one the following annotations:
559 .Bl -column YXZ description
560 .It * Ta work tree's base commit matches the branch tip
561 .It \(a~ Ta work tree's base commit is out-of-date
562 .El
563 .It Fl d Ar name
564 Delete the branch with the specified name from the repository.
565 Only the branch reference is deleted.
566 Any commit, tree, and blob objects belonging to the branch
567 remain in the repository and may be removed separately with
568 Git's garbage collector.
569 .El
570 .It Cm br
571 Short alias for
572 .Cm branch .
573 .It Cm tag Oo Fl m Ar message Oc Oo Fl r Ar repository-path Oc Oo Fl l Oc Ar name Op Ar commit
574 Manage tags in a repository.
575 .Pp
576 Tags are managed via references which live in the
577 .Dq refs/tags/
578 reference namespace.
579 The
580 .Cm got tag
581 command operates on references in this namespace only.
582 References in this namespace point at tag objects which contain a pointer
583 to another object, a tag message, as well as author and timestamp information.
584 .Pp
585 Expect one or two arguments and attempt to create a tag with the given
586 .Ar name ,
587 and make this tag point at the given
588 .Ar commit .
589 If no commit is specified, default to the latest commit on the work tree's
590 current branch if invoked in a work tree, and to a commit resolved via
591 the repository's HEAD reference otherwise.
592 Otherwise, the expected argument is a commit ID SHA1 hash or an existing
593 reference or tag name which will be resolved to a commit ID.
594 An abbreviated hash argument will be expanded to a full SHA1 hash
595 automatically, provided the abbreviation is unique.
596 .Pp
597 The options for
598 .Cm got tag
599 are as follows:
600 .Bl -tag -width Ds
601 .It Fl m Ar message
602 Use the specified tag message when creating the new tag
603 Without the
604 .Fl m
605 option,
606 .Cm got tag
607 opens a temporary file in an editor where a tag message can be written.
608 .It Fl r Ar repository-path
609 Use the repository at the specified path.
610 If not specified, assume the repository is located at or above the current
611 working directory.
612 If this directory is a
613 .Nm
614 work tree, use the repository path associated with this work tree.
615 .It Fl l
616 List all existing tags in the repository instead of creating a new tag.
617 If this option is used, no other command-line arguments are allowed.
618 .El
619 .Pp
620 By design, the
621 .Cm got tag
622 command will not delete tags or change existing tags.
623 If a tag must be deleted, the
624 .Cm got ref
625 command may be used to delete a tag's reference.
626 This should only be done if the tag has not already been copied to

884 and the work tree's current branch, and stops once the tip commit
885 of the specified
886 .Ar branch

891 Commits on this branch represent the same changes with the same log
892 messages as their counterparts on the original
893 .Ar branch ,
894 but with different commit IDs.
895 Once rebasing has completed successfully, the temporary branch becomes
896 the new version of the specified

971 which can be edited interactively or passed on the command line.
972 The format of the histedit script is line-based.
973 Each line in the script begins with a command name, followed by
974 whitespace and an argument.
975 For most commands, the expected argument is a commit ID SHA1 hash.

994 .Pp
995 Every commit in the history being edited must be mentioned in the script.
996 Lines may be re-ordered to change the order of commits in the edited history.
997 .Pp
998 Edited commits are accumulated on a temporary branch which the work tree
999 will remain switched to throughout the entire histedit operation.
1000 Once history editing has completed successfully, the temporary branch becomes
1001 the new version of the work tree's branch and the work tree is automatically
1002 switched to it.

1016 If merge conflicts occur the histedit operation is interrupted and may
1017 be continued once conflicts have been resolved.
1018 Alternatively, the histedit operation may be aborted which will leave
1019 the work tree switched back to its original branch.
1020 .Pp
1021 If a merge conflict is resolved in a way which renders the merged

1031 to a single base commit with
1032 .Cm got update .
1033 If changes have been staged with

1046 .Pp
1047 The

1049 command will refuse to run while a histedit operation is in progress.
1050 Other commands which manipulate the work tree may be used, and the

1375 .Pp
1376 Alternatively, for quick and dirty local testing of
1377 .Nm
1378 a new Git repository could be created and populated with files,
1379 e.g. from a temporary CVS checkout located at
1380 .Pa /tmp/src :
1381 .Pp
1382 .Dl $ got init /var/git/src.git
1383 .Dl $ got import -r /var/git/src.git -I CVS -I obj /tmp/src
1384 .Pp
1385 Check out a work tree from the Git repository to /usr/src:
1386 .Pp
1387 .Dl $ got checkout /var/git/src.git /usr/src
1388 .Pp
1389 View local changes in a work tree directory:
1390 .Pp
1391 .Dl $ got status
1392 .Dl $ got diff | less
1393 .Pp
1394 Interactively revert selected local changes in a work tree directory:
1395 .Pp
1396 .Dl $ got revert -p -R\ .
1397 .Pp
1398 In a work tree or a git repository directory, list all branch references:
1399 .Pp
1400 .Dl $ got branch -l
1401 .Pp
1402 In a work tree or a git repository directory, create a new branch called
1403 .Dq unified-buffer-cache
1404 which is forked off the
1405 .Dq master
1406 branch:
1407 .Pp
1408 .Dl $ got branch unified-buffer-cache master
1409 .Pp
1410 Switch an existing work tree to the branch
1411 .Dq unified-buffer-cache .
1412 Local changes in the work tree will be preserved and merged if necessary:
1413 .Pp
1414 .Dl $ got update -b unified-buffer-cache
1415 .Pp
1416 Create a new commit from local changes in a work tree directory.
1417 This new commit will become the head commit of the work tree's current branch:
1418 .Pp
1419 .Dl $ got commit
1420 .Pp
1421 In a work tree or a git repository directory, view changes committed in
1422 the 3 most recent commits to the work tree's branch, or the branch resolved
1423 via the repository's HEAD reference, respectively:
1424 .Pp
1425 .Dl $ got log -p -l 3 -f
1426 .Pp
1427 Add new files and remove obsolete files in a work tree directory:

1429 .Dl $ got add sys/uvm/uvm_ubc.c
1430 .Dl $ got remove sys/uvm/uvm_vnode.c
1431 .Pp
1432 Create a new commit from local changes in a work tree directory
1433 with a pre-defined log message.
1434 .Pp
1435 .Dl $ got commit -m 'unify the buffer cache'
1436 .Pp
1437 Update any work tree checked out from the
1438 .Dq unified-buffer-cache
1439 branch to the latest commit on this branch:
1440 .Pp
1441 .Dl $ got update
1442 .Pp
1443 Roll file content on the unified-buffer-cache branch back by one commit,
1444 and then fetch the rolled-back change into the work tree as a local change
1445 to be amended and perhaps committed again:
1446 .Pp
1447 .Dl $ got backout unified-buffer-cache
1448 .Dl $ got commit -m 'roll back previous'
1449 .Dl $ # now back out the previous backout :-)
1450 .Dl $ got backout unified-buffer-cache
1451 .Pp
1452 Fetch new upstream commits into the local repository's master branch.
1453 This step currently requires
1454 .Xr git 1 :
1455 .Pp
1456 .Dl $ cd /var/git/src.git
1457 .Dl $ git fetch origin master:master
1458 .Pp
1459 Rebase the
1460 .Dq unified-buffer-cache
1461 branch on top of the new head commit of the
1462 .Dq master
1463 branch.
1464 .Pp
1465 .Dl $ got update -b master
1466 .Dl $ got rebase unified-buffer-cache
1467 .Pp
1468 Create a patch from all changes on the unified-buffer-cache branch.
1469 The patch can be mailed out for review and applied to

1471 CVS tree:
1472 .Pp
1473 .Dl $ got diff master unified-buffer-cache > /tmp/ubc.diff
1474 .Pp

1483 Additional steps are necessary if local changes need to be pushed back
1484 to the remote repository, which currently requires
1485 .Cm git fetch
1486 and
1487 .Cm git push .
1488 Before working against existing branches in a repository cloned with
1489 .Dq git clone --bare ,
1490 a Git
1491 .Dq refspec
1492 must be configured to map all references in the remote repository
1493 into the
1494 .Dq refs/remotes
1495 namespace of the local repository.
1496 This can achieved by setting Git's
1497 .Pa remote.origin.fetch
1498 configuration variable to the value
1499 .Dq +refs/heads/*:refs/remotes/origin/*
1500 with the
1501 .Cm git config
1502 command:
1503 .Pp
1504 .Dl $ cd /var/git/repo
1505 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
1506 .Pp
1507 Alternatively, the following
1508 .Pa fetch
1509 configuration item can be added manually to the Git repository's
1510 .Pa config
1511 file:
1512 .Pp
1513 .Dl [remote "origin"]
1514 .Dl url = ...
1515 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
1516 .Pp
1517 This configuration leaves the local repository's
1518 .Dq refs/heads
1519 namespace free for use by local branches checked out with
1520 .Cm got checkout
1521 and, if needed, created with
1522 .Cm got branch .
1523 .Pp
1524 Branches in the
1525 .Dq remotes/origin
1526 namespace can be updated with incoming changes from the remote
1527 repository with
1528 .Cm git fetch :
1529 .Pp
1530 .Dl $ cd /var/git/repo
1531 .Dl $ git fetch
1532 .Pp
1533 Before outgoing changes on the local
1534 .Dq master
1535 branch can be pushed to the remote repository, the local
1536 .Dq master
1537 branch must be rebased onto the
1538 .Dq origin/master
1539 branch:
1540 .Pp
1541 .Dl $ got update -b origin/master
1542 .Dl $ got rebase master
1543 .Pp
1544 Changes on the local
1545 .Dq master
1546 branch can then be pushed to the remote
1547 repository with
1548 .Cm git push :
1549 .Pp
1550 .Dl $ cd /var/git/repo
1551 .Dl $ git push origin master
1552 .Pp
1553 In order to merge changes committed to the
1554 .Dq unified-buffer-cache
1555 branch back into the
1556 .Dq master
1557 branch, the
1558 .Dq unified-buffer-cache
1559 branch must first be rebased onto the
1560 .Dq master
1561 branch:
1562 .Pp
1563 .Dl $ got update -b master
1564 .Dl $ got rebase unified-buffer-cache
1565 .Pp
1566 Changes on the
1567 .Dq unified-buffer-cache
1568 branch can now be made visible on the
1569 .Dq master
1570 branch with
1571 .Cm got integrate .
1572 Because the rebase operation switched the work tree to the
1573 .Dq unified-buffer-cache
1574 branch, the work tree must be switched back to the
1575 .Dq master
1576 branch before the
1577 .Dq unified-buffer-cache
1578 branch can be integrated into
1579 .Dq master :
1580 .Pp
1581 .Dl $ got update -b master
1582 .Dl $ got integrate unified-buffer-cache
