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, -version
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 E Oc 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 Show the status of each affected file, using the following status codes:
142 .Bl -column YXZ description
143 .It A Ta new file was added
144 .It E Ta file already exists in work tree's meta-data
145 .El
146 .Pp
147 If the
148 .Ar work tree path
149 is not specified, either use the last component of
150 .Ar repository path ,
151 or if a
152 .Ar path prefix
153 was specified use the last component of
154 .Ar path prefix .
155 .Pp
156 The options for
157 .Cm got checkout
158 are as follows:
159 .Bl -tag -width Ds
160 .It Fl E
161 Proceed with the checkout operation even if the directory at
162 .Ar work-tree-path
163 is not empty.
164 Existing files will be left intact.
165 .It Fl b Ar branch
166 Check out files from a commit on the specified
167 .Ar branch .
168 If this option is not specified, a branch resolved via the repository's HEAD
169 reference will be used.
170 .It Fl c Ar commit
171 Check out files from the specified
172 .Ar commit
173 on the selected branch.
174 The expected argument is a commit ID SHA1 hash or an existing reference
175 or tag name which will be resolved to a commit ID.
176 An abbreviated hash argument will be expanded to a full SHA1 hash
177 automatically, provided the abbreviation is unique.
178 If this option is not specified, the most recent commit on the selected
179 branch will be used.
180 .It Fl p Ar path-prefix
181 Restrict the work tree to a subset of the repository's tree hierarchy.
182 Only files beneath the specified
183 .Ar path-prefix
184 will be checked out.
185 .El
186 .It Cm co
187 Short alias for
188 .Cm checkout .
189 .It Cm update Oo Fl b Ar branch Oc Oo Fl c Ar commit Oc Op Ar path ...
190 Update an existing work tree to a different commit.
191 Show the status of each affected file, using the following status codes:
192 .Bl -column YXZ description
193 .It U Ta file was updated and contained no local changes
194 .It G Ta file was updated and local changes were merged cleanly
195 .It C Ta file was updated and conflicts occurred during merge
196 .It D Ta file was deleted
197 .It A Ta new file was added
198 .It \(a~ Ta versioned file is obstructed by a non-regular file
199 .It ! Ta a missing versioned file was restored
200 .El
201 .Pp
202 If no
203 .Ar path
204 is specified, update the entire work tree.
205 Otherwise, restrict the update operation to files at or within the
206 specified paths.
207 Each path is required to exist in the update operation's target commit.
208 Files in the work tree outside specified paths will remain unchanged and
209 will retain their previously recorded base commit.
210 Some
211 .Nm
212 commands may refuse to run while the work tree contains files from
213 multiple base commits.
214 The base commit of such a work tree can be made consistent by running
215 .Cm got update
216 across the entire work tree.
217 Specifying a
218 .Ar path
219 is incompatible with the
220 .Fl b
221 option.
222 .Pp
223 .Cm got update
224 cannot update paths with staged changes.
225 If changes have been staged with
226 .Cm got stage ,
227 these changes must first be committed with
228 .Cm got commit
229 or unstaged with
230 .Cm got unstage .
231 .Pp
232 The options for
233 .Cm got update
234 are as follows:
235 .Bl -tag -width Ds
236 .It Fl b Ar branch
237 Switch the work tree's branch reference to the specified
238 .Ar branch
239 before updating the work tree.
240 This option requires that all paths in the work tree are updated.
241 .It Fl c Ar commit
242 Update the work tree to the specified
243 .Ar commit .
244 The expected argument is a commit ID SHA1 hash or an existing reference
245 or tag name which will be resolved to a commit ID.
246 An abbreviated hash argument will be expanded to a full SHA1 hash
247 automatically, provided the abbreviation is unique.
248 If this option is not specified, the most recent commit on the work tree's
249 branch will be used.
250 .El
251 .It Cm up
252 Short alias for
253 .Cm update .
254 .It Cm status Op Ar path ...
255 Show the current modification status of files in a work tree,
256 using the following status codes:
257 .Bl -column YXZ description
258 .It M Ta modified file
259 .It A Ta file scheduled for addition in next commit
260 .It D Ta file scheduled for deletion in next commit
261 .It C Ta modified or added file which contains merge conflicts
262 .It ! Ta versioned file was expected on disk but is missing
263 .It \(a~ Ta versioned file is obstructed by a non-regular file
264 .It ? Ta unversioned item not tracked by
265 .Nm
266 .It m Ta modified file modes (executable bit only)
267 .It N Ta non-existent
268 .Ar path
269 specified on the command line
270 .El
271 .Pp
272 If no
273 .Ar path
274 is specified, show modifications in the entire work tree.
275 Otherwise, show modifications at or within the specified paths.
276 .Pp
277 If changes have been staged with
278 .Cm got stage ,
279 staged changes are shown in the second output column, using the following
280 status codes:
281 .Bl -column YXZ description
282 .It M Ta file modification is staged
283 .It A Ta file addition is staged
284 .It D Ta file deletion is staged
285 .El
286 .Pp
287 Changes created on top of staged changes are indicated in the first column:
288 .Bl -column YXZ description
289 .It MM Ta file was modified after earlier changes have been staged
290 .It MA Ta file was modified after having been staged for addition
291 .El
292 .Pp
293 For compatibility with
294 .Xr cvs 1
295 and
296 .Xr git 1 ,
297 .Cm got status
298 reads
299 .Xr glob 7
300 patterns from
301 .Pa .cvsignore
302 and
303 .Pa .gitignore
304 files in each traversed directory and will not display unversioned files
305 which match these patterns.
306 As an extension to
307 .Xr glob 7
308 matching rules,
309 .Cm got status
310 supports consecutive asterisks,
311 .Dq ** ,
312 which will match an arbitrary amount of directories.
313 Unlike
314 .Xr cvs 1 ,
315 .Cm got status
316 only supports a single ignore pattern per line.
317 Unlike
318 .Xr git 1 ,
319 .Cm got status
320 does not support negated ignore patterns prefixed with
321 .Dq \&! ,
322 and gives no special significance to the location of path component separators,
323 .Dq / ,
324 in a pattern.
325 .It Cm st
326 Short alias for
327 .Cm status .
328 .It Cm log Oo Fl b Oc Oo Fl c Ar commit Oc Oo Fl C Ar number 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
329 Display history of a repository.
330 If a
331 .Ar path
332 is specified, show only commits which modified this path.
333 If invoked in a work tree, the
334 .Ar path
335 is interpreted relative to the current working directory,
336 and the work tree's path prefix is implicitly prepended.
337 Otherwise, the path is interpreted relative to the repository root.
338 .Pp
339 The options for
340 .Cm got log
341 are as follows:
342 .Bl -tag -width Ds
343 .It Fl b
344 Display individual commits which were merged into the current branch
345 from other branches.
346 By default,
347 .Cm got log
348 shows the linear history of the current branch only.
349 .It Fl c Ar commit
350 Start traversing history at the specified
351 .Ar commit .
352 The expected argument is a commit ID SHA1 hash or an existing reference
353 or tag name which will be resolved to a commit ID.
354 An abbreviated hash argument will be expanded to a full SHA1 hash
355 automatically, provided the abbreviation is unique.
356 If this option is not specified, default to the work tree's current branch
357 if invoked in a work tree, or to the repository's HEAD reference.
358 .It Fl C Ar number
359 Set the number of context lines shown in diffs with
360 .Fl p .
361 By default, 3 lines of context are shown.
362 .It Fl l Ar N
363 Limit history traversal to a given number of commits.
364 If this option is not specified, a default limit value of zero is used,
365 which is treated as an unbounded limit.
366 The
367 .Ev GOT_LOG_DEFAULT_LIMIT
368 environment variable may be set to change this default value.
369 .It Fl p
370 Display the patch of modifications made in each commit.
371 If a
372 .Ar path
373 is specified, only show the patch of modifications at or within this path.
374 .It Fl s Ar search-pattern
375 If specified, show only commits with a log message matched by the extended
376 regular expression
377 .Ar search-pattern .
378 Regular expression syntax is documented in
379 .Xr re_format 7 .
380 .It Fl r Ar repository-path
381 Use the repository at the specified path.
382 If not specified, assume the repository is located at or above the current
383 working directory.
384 If this directory is a
385 .Nm
386 work tree, use the repository path associated with this work tree.
387 .El
388 .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
389 When invoked within a work tree with less than two arguments, display
390 uncommitted changes in the work tree.
391 If a
392 .Ar path
393 is specified, only show changes within this path.
394 .Pp
395 If two arguments are provided, treat each argument as a reference, a tag
396 name, or an object ID SHA1 hash, and display differences between the
397 corresponding objects.
398 Both objects must be of the same type (blobs, trees, or commits).
399 An abbreviated hash argument will be expanded to a full SHA1 hash
400 automatically, provided the abbreviation is unique.
401 .Pp
402 The options for
403 .Cm got diff
404 are as follows:
405 .Bl -tag -width Ds
406 .It Fl C Ar number
407 Set the number of context lines shown in the diff.
408 By default, 3 lines of context are shown.
409 .It Fl r Ar repository-path
410 Use the repository at the specified path.
411 If not specified, assume the repository is located at or above the current
412 working directory.
413 If this directory is a
414 .Nm
415 work tree, use the repository path associated with this work tree.
416 .It Fl s
417 Show changes staged with
418 .Cm got stage
419 instead of showing local changes.
420 This option is only valid when
421 .Cm got diff
422 is invoked in a work tree.
423 .It Fl w
424 Ignore whitespace-only changes.
425 .El
426 .It Cm di
427 Short alias for
428 .Cm diff .
429 .It Cm blame Oo Fl c Ar commit Oc Oo Fl r Ar repository-path Oc Ar path
430 Display line-by-line history of a file at the specified path.
431 .Pp
432 The options for
433 .Cm got blame
434 are as follows:
435 .Bl -tag -width Ds
436 .It Fl c Ar commit
437 Start traversing history at the specified
438 .Ar commit .
439 The expected argument is a commit ID SHA1 hash or an existing reference
440 or tag name which will be resolved to a commit ID.
441 An abbreviated hash argument will be expanded to a full SHA1 hash
442 automatically, provided the abbreviation is unique.
443 .It Fl r Ar repository-path
444 Use the repository at the specified path.
445 If not specified, assume the repository is located at or above the current
446 working directory.
447 If this directory is a
448 .Nm
449 work tree, use the repository path associated with this work tree.
450 .El
451 .It Cm bl
452 Short alias for
453 .Cm blame .
454 .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
455 Display a listing of files and directories at the specified
456 directory path in the repository.
457 Entries shown in this listing may carry one of the following trailing
458 annotations:
459 .Bl -column YXZ description
460 .It @ Ta entry is a symbolic link
461 .It / Ta entry is a directory
462 .It * Ta entry is an executable file
463 .It $ Ta entry is a Git submodule
464 .El
465 .Pp
466 If no
467 .Ar path
468 is specified, list the repository path corresponding to the current
469 directory of the work tree, or the root directory of the repository
470 if there is no work tree.
471 .Pp
472 The options for
473 .Cm got tree
474 are as follows:
475 .Bl -tag -width Ds
476 .It Fl c Ar commit
477 List files and directories as they appear in the specified
478 .Ar commit .
479 The expected argument is a commit ID SHA1 hash or an existing reference
480 or tag name which will be resolved to a commit ID.
481 An abbreviated hash argument will be expanded to a full SHA1 hash
482 automatically, provided the abbreviation is unique.
483 .It Fl r Ar repository-path
484 Use the repository at the specified path.
485 If not specified, assume the repository is located at or above the current
486 working directory.
487 If this directory is a
488 .Nm
489 work tree, use the repository path associated with this work tree.
490 .It Fl i
491 Show object IDs of files (blob objects) and directories (tree objects).
492 .It Fl R
493 Recurse into sub-directories in the repository.
494 .El
495 .It Cm tr
496 Short alias for
497 .Cm tree .
498 .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
499 Manage references in a repository.
500 .Pp
501 If no options are passed, expect two arguments and attempt to create,
502 or update, the reference with the given
503 .Ar name ,
504 and make it point at the given
505 .Ar target .
506 The name must be an absolute reference name, i.e. it must begin with
507 .Dq refs/ .
508 The target may be an object ID SHA1 hash or an existing reference which
509 will be resolved to an object ID.
510 An abbreviated hash argument will be expanded to a full SHA1 hash
511 automatically, provided the abbreviation is unique.
512 .Pp
513 The options for
514 .Cm got ref
515 are as follows:
516 .Bl -tag -width Ds
517 .It Fl r Ar repository-path
518 Use the repository at the specified path.
519 If not specified, assume the repository is located at or above the current
520 working directory.
521 If this directory is a
522 .Nm
523 work tree, use the repository path associated with this work tree.
524 .It Fl l
525 List all existing references in the repository.
526 .It Fl d Ar name
527 Delete the reference with the specified name from the repository.
528 .It Fl s
529 Create a symbolic reference pointing at the specified
530 .Ar target ,
531 which must be an existing reference.
532 Care should be taken not to create loops between references when
533 this option is used.
534 .El
535 .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 Oo Fl n Oc Op Ar name
536 Create, list, or delete branches.
537 .Pp
538 Branches are managed via references which live in the
539 .Dq refs/heads/
540 reference namespace.
541 The
542 .Cm got branch
543 command operates on references in this namespace only.
544 .Pp
545 If invoked in a work tree without any arguments, print the name of the
546 work tree's current branch.
547 .Pp
548 If a
549 .Ar name
550 argument is passed, attempt to create a branch reference with the given name.
551 By default the new branch reference will point at the latest commit on the
552 work tree's current branch if invoked in a work tree, and otherwise to a commit
553 resolved via the repository's HEAD reference.
554 .Pp
555 If invoked in a work tree, once the branch was created successfully
556 switch the work tree's head reference to the newly created branch and
557 update files across the entire work tree, just like
558 .Cm got update -b Ar name
559 would do.
560 Show the status of each affected file, using the following status codes:
561 .Bl -column YXZ description
562 .It U Ta file was updated and contained no local changes
563 .It G Ta file was updated and local changes were merged cleanly
564 .It C Ta file was updated and conflicts occurred during merge
565 .It D Ta file was deleted
566 .It A Ta new file was added
567 .It \(a~ Ta versioned file is obstructed by a non-regular file
568 .It ! Ta a missing versioned file was restored
569 .El
570 .Pp
571 The options for
572 .Cm got branch
573 are as follows:
574 .Bl -tag -width Ds
575 .It Fl c Ar commit
576 Make a newly created branch reference point at the specified
577 .Ar commit .
578 The expected
579 .Ar commit
580 argument is a commit ID SHA1 hash or an existing reference
581 or tag name which will be resolved to a commit ID.
582 .It Fl r Ar repository-path
583 Use the repository at the specified path.
584 If not specified, assume the repository is located at or above the current
585 working directory.
586 If this directory is a
587 .Nm
588 work tree, use the repository path associated with this work tree.
589 .It Fl l
590 List all existing branches in the repository.
591 If invoked in a work tree, the work tree's current branch is shown
592 with one the following annotations:
593 .Bl -column YXZ description
594 .It * Ta work tree's base commit matches the branch tip
595 .It \(a~ Ta work tree's base commit is out-of-date
596 .El
597 .It Fl d Ar name
598 Delete the branch with the specified name from the repository.
599 Only the branch reference is deleted.
600 Any commit, tree, and blob objects belonging to the branch
601 remain in the repository and may be removed separately with
602 Git's garbage collector.
603 .It Fl n
604 Do not switch and update the work tree after creating a new branch.
605 .El
606 .It Cm br
607 Short alias for
608 .Cm branch .
609 .It Cm tag Oo Fl c Ar commit Oc Oo Fl m Ar message Oc Oo Fl r Ar repository-path Oc Oo Fl l Oc Ar name
610 Manage tags in a repository.
611 .Pp
612 Tags are managed via references which live in the
613 .Dq refs/tags/
614 reference namespace.
615 The
616 .Cm got tag
617 command operates on references in this namespace only.
618 References in this namespace point at tag objects which contain a pointer
619 to another object, a tag message, as well as author and timestamp information.
620 .Pp
621 Attempt to create a tag with the given
622 .Ar name ,
623 and make this tag point at the given

928 The
929 .Ar branch
930 must share common ancestry with the work tree's current branch.
931 Rebasing begins with the first descendant commit of the youngest
932 common ancestor commit shared by the specified
933 .Ar branch
934 and the work tree's current branch, and stops once the tip commit
935 of the specified
936 .Ar branch
937 has been rebased.
938 .Pp
939 When
940 .Cm got rebase
941 is used as intended, the specified
942 .Ar branch
943 contains changes made in local commits that are not yet visible in any
944 other repositories.
945 The work tree's current branch, which must be set with
946 .Cm got update -b
947 before starting the
948 .Cm rebase
949 operation, represents a branch from a remote repository which shares
950 a common history with the specified
951 .Ar branch
952 but has at some point diverged due to commits added to the remote repository.
953 .Pp
954 Rebased commits are accumulated on a temporary branch which the work tree
955 will remain switched to throughout the entire rebase operation.
956 Commits on this branch represent the same changes with the same log
957 messages as their counterparts on the original
958 .Ar branch ,
959 but with different commit IDs.
960 Once rebasing has completed successfully, the temporary branch becomes
961 the new version of the specified
962 .Ar branch
963 and the work tree is automatically switched to it.
964 .Pp
965 While rebasing commits, show the status of each affected file,
966 using the following status codes:

975 .El
976 .Pp
977 If merge conflicts occur the rebase operation is interrupted and may
978 be continued once conflicts have been resolved.
979 Alternatively, the rebase operation may be aborted which will leave
980 .Ar branch
981 unmodified and the work tree switched back to its original branch.
982 .Pp
983 If a merge conflict is resolved in a way which renders the merged
984 change into a no-op change, the corresponding commit will be elided
985 when the rebase operation continues.
986 .Pp
987 .Cm got rebase
988 will refuse to run if certain preconditions are not met.
989 If the work tree is not yet fully updated to the tip commit of its
990 branch then the work tree must first be updated with
991 .Cm got update .
992 If changes have been staged with
993 .Cm got stage ,
994 these changes must first be committed with

998 If the work tree contains local changes, these changes must first be
999 committed with

1036 operation the work tree's current branch must be set with
1037 .Cm got update -b
1038 to the branch which should be edited, unless this branch is already the
1039 current branch of the work tree.
1040 The tip of this branch represents the upper bound (inclusive) of commits
1041 touched by the
1042 .Cm histedit
1043 operation.
1044 .Pp
1045 Furthermore, the work tree's base commit
1046 must be set with
1047 .Cm got update -c
1048 to a point in this branch's commit history where editing should begin.
1049 This commit represents the lower bound (non-inclusive) of commits touched
1050 by the
1051 .Cm histedit
1052 operation.
1053 .Pp
1054 Editing of commit history is controlled via a
1055 .Ar histedit script
1056 which can be written in an editor based on a template, passed on the
1057 command line, or generated with the
1058 .Fl m
1059 option if only log messages need to be edited.
1060 .Pp
1061 The format of the histedit script is line-based.
1062 Each line in the script begins with a command name, followed by
1063 whitespace and an argument.
1064 For most commands, the expected argument is a commit ID SHA1 hash.
1065 Any remaining text on the line is ignored.
1066 Lines which begin with the
1067 .Sq #
1068 character are ignored entirely.

1076 listed further below that will be used.
1077 .It drop Ar commit Ta Remove this commit from the edited history.
1078 .It mesg Ar log-message Ta Use the specified single-line log message for
1079 the commit on the previous line.
1080 If the log message argument is left empty, open an editor where a new
1081 log message can be written.
1082 .El
1083 .Pp
1084 Every commit in the history being edited must be mentioned in the script.
1085 Lines may be re-ordered to change the order of commits in the edited history.
1086 .Pp
1087 Edited commits are accumulated on a temporary branch which the work tree
1088 will remain switched to throughout the entire histedit operation.
1089 Once history editing has completed successfully, the temporary branch becomes
1090 the new version of the work tree's branch and the work tree is automatically
1091 switched to it.
1092 .Pp
1093 While merging commits, show the status of each affected file,

1481 Alternatively, for quick and dirty local testing of

1494 View local changes in a work tree directory:

1498 .Pp
1499 Interactively revert selected local changes in a work tree directory:
1500 .Pp
1501 .Dl $ got revert -p -R\ .
1502 .Pp
1503 In a work tree or a git repository directory, list all branch references:
1504 .Pp
1505 .Dl $ got branch -l
1506 .Pp
1507 In a work tree or a git repository directory, create a new branch called
1508 .Dq unified-buffer-cache
1509 which is forked off the
1510 .Dq master
1511 branch:
1512 .Pp
1513 .Dl $ got branch unified-buffer-cache master
1514 .Pp
1515 Switch an existing work tree to the branch
1516 .Dq unified-buffer-cache .
1517 Local changes in the work tree will be preserved and merged if necessary:
1518 .Pp
1519 .Dl $ got update -b unified-buffer-cache
1520 .Pp
1521 Create a new commit from local changes in a work tree directory.
1522 This new commit will become the head commit of the work tree's current branch:
1523 .Pp
1524 .Dl $ got commit
1525 .Pp
1526 In a work tree or a git repository directory, view changes committed in

1529 .Pp

1532 In a work tree or a git repository directory, log the history of a subdirectory:
1533 .Pp

1535 .Pp
1536 While operating inside a work tree, paths are specified relative to the current

1560 .Dl $ got update
1561 .Pp
1562 Roll file content on the unified-buffer-cache branch back by one commit,
1563 and then fetch the rolled-back change into the work tree as a local change

1565 .Pp
1566 .Dl $ got backout unified-buffer-cache

1568 .Dl $ # now back out the previous backout :-)
1569 .Dl $ got backout unified-buffer-cache
1570 .Pp
1571 Fetch new upstream commits into the local repository's master branch.

1575 .Dl $ cd /var/git/src.git
1576 .Dl $ git fetch origin master:master
1577 .Pp
1578 Rebase the

1584 .Dl $ got update -b master
1585 .Dl $ got rebase unified-buffer-cache

1602 Additional steps are necessary if local changes need to be pushed back
1603 to the remote repository, which currently requires
1604 .Cm git fetch
1605 and
1606 .Cm git push .
1607 Before working against existing branches in a repository cloned with
1608 .Dq git clone --bare ,
1609 a Git
1610 .Dq refspec
1611 must be configured to map all references in the remote repository
1612 into the
1613 .Dq refs/remotes
1614 namespace of the local repository.
1615 This can achieved by setting Git's
1616 .Pa remote.origin.fetch
1617 configuration variable to the value
1618 .Dq +refs/heads/*:refs/remotes/origin/*
1619 with the
1620 .Cm git config
1621 command:
1622 .Pp
1623 .Dl $ cd /var/git/repo
1624 .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*'
1625 .Pp
1626 Alternatively, the following
1627 .Pa fetch
1628 configuration item can be added manually to the Git repository's
1629 .Pa config
1630 file:
1631 .Pp
1632 .Dl [remote "origin"]
1633 .Dl url = ...
1634 .Dl fetch = +refs/heads/*:refs/remotes/origin/*
1635 .Pp
1636 This configuration leaves the local repository's
1637 .Dq refs/heads
1638 namespace free for use by local branches checked out with
1639 .Cm got checkout
1640 and, if needed, created with
1641 .Cm got branch .
1642 .Pp
1643 Branches in the
1644 .Dq remotes/origin
1645 namespace can be updated with incoming changes from the remote
1646 repository with
1647 .Cm git fetch :
1648 .Pp
1649 .Dl $ cd /var/git/repo
1650 .Dl $ git fetch
1651 .Pp
1652 To make changes fetched from the remote repository appear on the
1653 .Dq master
1654 branch, the
1655 .Dq master
1656 branch must be rebased onto the
1657 .Dq origin/master
1658 branch.
1659 This will also merge local changes, if any, with the incoming changes:
1660 .Pp
1661 .Dl $ got update -b origin/master
1662 .Dl $ got rebase master
1663 .Pp
1664 On the
1665 .Dq master
1666 branch, log messages for local changes can now be amended with
1667 .Dq OK
1668 by other developers and any other important new information:
1669 .Pp
1670 .Dl $ got update -c origin/master
1671 .Dl $ got histedit -m
1672 .Pp
1673 Local changes on the
1674 .Dq master
1675 branch can then be pushed to the remote
1676 repository with
1677 .Cm git push :
1678 .Pp
1679 .Dl $ cd /var/git/repo
1680 .Dl $ git push origin master
1681 .Pp
1682 In order to merge changes committed to the
1683 .Dq unified-buffer-cache
1684 branch back into the
1685 .Dq master
1686 branch, the
1687 .Dq unified-buffer-cache
1688 branch must first be rebased onto the
1689 .Dq master
1690 branch:
1691 .Pp
1692 .Dl $ got update -b master
1693 .Dl $ got rebase unified-buffer-cache
1694 .Pp
1695 Changes on the
1696 .Dq unified-buffer-cache
1697 branch can now be made visible on the
1698 .Dq master
1699 branch with
1700 .Cm got integrate .
1701 Because the rebase operation switched the work tree to the
1702 .Dq unified-buffer-cache
1703 branch, the work tree must be switched back to the
1704 .Dq master
1705 branch before the
1706 .Dq unified-buffer-cache
1707 branch can be integrated into
1708 .Dq master :
1709 .Pp
1710 .Dl $ got update -b master
