30 | DESCRIPTION | |
31 | ----------- | |
2052d146 | 32 | |
8a1d076e | 33 | Prepare each commit with its patch in |
2052d146 | 34 | one file per commit, formatted to resemble UNIX mailbox format. |
2052d146 | 35 | The output of this command is convenient for e-mail submission or |
0b444cdb | 36 | for use with 'git am'. |
35ef3a4c | 37 | |
8a1d076e JH |
38 | There are two ways to specify which commits to operate on. |
39 | ||
40 | 1. A single commit, <since>, specifies that the commits leading | |
41 | to the tip of the current branch that are not in the history | |
42 | that leads to the <since> to be output. | |
43 | ||
44 | 2. Generic <revision range> expression (see "SPECIFYING | |
9d83e382 | 45 | REVISIONS" section in linkgit:gitrevisions[7]) means the |
2f6a3823 JH |
46 | commits in the specified range. |
47 | ||
2d266f9d TR |
48 | The first rule takes precedence in the case of a single <commit>. To |
49 | apply the second rule, i.e., format everything since the beginning of | |
9e9f132f | 50 | history up until <commit>, use the `--root` option: `git format-patch |
6cf378f0 | 51 | --root <commit>`. If you want to format only <commit> itself, you |
dce5ef14 | 52 | can do this with `git format-patch -1 <commit>`. |
8a1d076e | 53 | |
e6ff0f42 | 54 | By default, each output file is numbered sequentially from 1, and uses the |
2052d146 | 55 | first line of the commit message (massaged for pathname safety) as |
dce5ef14 | 56 | the filename. With the `--numbered-files` option, the output file names |
e6ff0f42 JL |
57 | will only be numbers, without the first line of the commit appended. |
58 | The names of the output files are printed to standard | |
dce5ef14 | 59 | output, unless the `--stdout` option is specified. |
66f04f38 | 60 | |
dce5ef14 | 61 | If `-o` is specified, output files are created in <dir>. Otherwise |
bc6bf2d7 | 62 | they are created in the current working directory. The default path |
ae9f6311 | 63 | can be set with the `format.outputDirectory` configuration option. |
bc6bf2d7 AK |
64 | The `-o` option takes precedence over `format.outputDirectory`. |
65 | To store patches in the current working directory even when | |
66 | `format.outputDirectory` points elsewhere, use `-o .`. | |
35ef3a4c | 67 | |
52ffe995 JW |
68 | By default, the subject of a single patch is "[PATCH] " followed by |
69 | the concatenation of lines from the commit message up to the first blank | |
70 | line (see the DISCUSSION section of linkgit:git-commit[1]). | |
71 | ||
72 | When multiple patches are output, the subject prefix will instead be | |
73 | "[PATCH n/m] ". To force 1/1 to be added for a single patch, use `-n`. | |
74 | To omit patch numbers from the subject, use `-N`. | |
35ef3a4c | 75 | |
dce5ef14 BG |
76 | If given `--thread`, `git-format-patch` will generate `In-Reply-To` and |
77 | `References` headers to make the second and subsequent patch mails appear | |
78 | as replies to the first mail; this also generates a `Message-Id` header to | |
cc35de84 | 79 | reference. |

3240240f SB |
114 | -s:: |
115 | --signoff:: | |
6f855371 NW |
116 | Add `Signed-off-by:` line to the commit message, using |
117 | the committer identity of yourself. | |
b2c150d3 | 118 | See the signoff option in linkgit:git-commit[1] for more information. |
6f855371 | 119 | |
54ba6013 | 120 | --stdout:: |
2052d146 DS |
121 | Print all commits to the standard output in mbox format, |
122 | instead of creating a file for each one. | |
7fc9d69f | 123 | |
c112f689 JS |
124 | --attach[=<boundary>]:: |
125 | Create multipart/mixed attachment, the first part of | |
126 | which is the commit message and the patch itself in the | |
dce5ef14 | 127 | second part, with `Content-Disposition: attachment`. |
c112f689 | 128 | |
0db5260b JW |
129 | --no-attach:: |
130 | Disable the creation of an attachment, overriding the | |
131 | configuration setting. | |
132 | ||
c112f689 JS |
133 | --inline[=<boundary>]:: |
134 | Create multipart/mixed attachment, the first part of | |
135 | which is the commit message and the patch itself in the | |
dce5ef14 | 136 | second part, with `Content-Disposition: inline`. |
a15a44ef | 137 | |
30984ed2 | 138 | --thread[=<style>]:: |
f693b7e9 | 139 | --no-thread:: |
dce5ef14 | 140 | Controls addition of `In-Reply-To` and `References` headers to |
f693b7e9 | 141 | make the second and subsequent mails appear as replies to the |
dce5ef14 | 142 | first. Also controls generation of the `Message-Id` header to |
f693b7e9 | 143 | reference. |
30984ed2 TR |
144 | + |
145 | The optional <style> argument can be either `shallow` or `deep`. | |
fd1ff306 | 146 | 'shallow' threading makes every mail a reply to the head of the |
30984ed2 | 147 | series, where the head is chosen from the cover letter, the |
6cf378f0 | 148 | `--in-reply-to`, and the first patch mail, in this order. 'deep' |
f693b7e9 YD |
149 | threading makes every mail a reply to the previous one. |
150 | + | |
ae9f6311 | 151 | The default is `--no-thread`, unless the `format.thread` configuration |
dce5ef14 | 152 | is set. If `--thread` is specified without a style, it defaults to the |
ae9f6311 | 153 | style specified by `format.thread` if any, or else `shallow`. |
f693b7e9 YD |
154 | + |
155 | Beware that the default for 'git send-email' is to thread emails | |
dce5ef14 BG |
156 | itself. If you want `git format-patch` to take care of threading, you |
157 | will want to ensure that threading is disabled for `git send-email`. | |
28ffb898 | 158 | |
da56645d | 159 | --in-reply-to=Message-Id:: |
dce5ef14 | 160 | Make the first mail (or all the mails with `--no-thread`) appear as a |
da56645d JT |
161 | reply to the given Message-Id, which avoids breaking threads to |
162 | provide a new patch series. | |
163 | ||
cc75ad67 DK |
164 | --ignore-if-in-upstream:: |
165 | Do not include a patch that matches a commit in | |
166 | <until>..<since>. This will examine all patches reachable | |
167 | from <since> but not from <until> and compare them with the | |
168 | patches being generated, and any patch that matches is | |
169 | ignored. | |
170 | ||
2d9e4a47 RJ |
171 | --subject-prefix=<Subject-Prefix>:: |
172 | Instead of the standard '[PATCH]' prefix in the subject | |
173 | line, instead use '[<Subject-Prefix>]'. This | |
174 | allows for useful naming of a patch series, and can be | |
dce5ef14 | 175 | combined with the `--numbered` option. |
2d9e4a47 | 176 | |
68e83a5b JT |
177 | --rfc:: |
178 | Alias for `--subject-prefix="RFC PATCH"`. RFC means "Request For | |
179 | Comments"; use this when sending an experimental patch for | |
180 | discussion rather than application. | |
181 | ||
7952ea66 | 182 | -v <n>:: |
4aad08e0 JH |
183 | --reroll-count=<n>:: |
184 | Mark the series as the <n>-th iteration of the topic. The | |
d614f075 | 185 | output filenames have `v<n>` prepended to them, and the |
4aad08e0 JH |
186 | subject prefix ("PATCH" by default, but configurable via the |
187 | `--subject-prefix` option) has ` v<n>` appended to it. E.g. | |
188 | `--reroll-count=4` may produce `v4-0001-add-makefile.patch` | |
189 | file that has "Subject: [PATCH v4 1/20] Add makefile" in it. | |
190 | ||
ae6c098f SD |
191 | --to=<email>:: |
192 | Add a `To:` header to the email headers. This is in addition | |
193 | to any configured headers, and may be used multiple times. | |
b2cd17b9 TR |
194 | The negated form `--no-to` discards all `To:` headers added so |
195 | far (from config or command line). | |
ae6c098f | 196 | |
736cc67d | 197 | --cc=<email>:: |
dce5ef14 | 198 | Add a `Cc:` header to the email headers. This is in addition |
736cc67d | 199 | to any configured headers, and may be used multiple times. |
b2cd17b9 TR |
200 | The negated form `--no-cc` discards all `Cc:` headers added so |
201 | far (from config or command line). | |
736cc67d | 202 | |
a9080475 JK |
203 | --from:: |
204 | --from=<ident>:: | |
205 | Use `ident` in the `From:` header of each commit email. If the | |
206 | author ident of the commit is not textually identical to the | |
207 | provided `ident`, place a `From:` header in the body of the | |
208 | message with the original author. If no `ident` is given, use | |
209 | the committer ident. | |
210 | + | |
211 | Note that this option is only useful if you are actually sending the | |
212 | emails and want to identify yourself as the sender, but retain the | |
213 | original author (and `git am` will correctly pick up the in-body | |
214 | header). Note also that `git send-email` already handles this | |
215 | transformation for you, and this option should not be used if you are | |
216 | feeding the result to `git send-email`. | |
217 | ||
d7d9c2d0 MH |
218 | --add-header=<header>:: |
219 | Add an arbitrary header to the email headers. This is in addition | |
220 | to any configured headers, and may be used multiple times. | |
b2cd17b9 TR |
221 | For example, `--add-header="Organization: git-foo"`. |
222 | The negated form `--no-add-header` discards *all* (`To:`, | |
223 | `Cc:`, and custom) headers added so far from config or command | |
224 | line. | |
d7d9c2d0 | 225 | |
2a4c2607 | 226 | --[no-]cover-letter:: |
f4912391 | 227 | In addition to the patches, generate a cover letter file |
561d2b79 | 228 | containing the branch description, shortlog and the overall diffstat. You can |
f4912391 | 229 | fill in a description in the file before sending it out. |
a5a27c79 | 230 | |
e422c0cf JH |
231 | --notes[=<ref>]:: |
232 | Append the notes (see linkgit:git-notes[1]) for the commit | |
233 | after the three-dash line. | |
234 | + | |
235 | The expected use case of this is to write supporting explanation for | |
6454d9f1 PO |
236 | the commit that does not belong to the commit log message proper, |
237 | and include it with the patch submission. While one can simply write | |
238 | these explanations after `format-patch` has run but before sending, | |
2de9b711 | 239 | keeping them as Git notes allows them to be maintained between versions |
6454d9f1 PO |
240 | of the patch series (but see the discussion of the `notes.rewrite` |
241 | configuration options in linkgit:git-notes[1] to use this workflow). | |
e422c0cf | 242 | |
2c7ee986 | 243 | --[no-]signature=<signature>:: |
6622d9c7 SB |
244 | Add a signature to each message produced. Per RFC 3676 the signature |
245 | is separated from the body by a line with '-- ' on it. If the | |
2de9b711 | 246 | signature option is omitted the signature defaults to the Git version |
6622d9c7 SB |
247 | number. |
248 | ||
7022650f JM |
249 | --signature-file=<file>:: |
250 | Works just like --signature except the signature is read from a file. | |
251 | ||
03eeaeae | 252 | --suffix=.<sfx>:: |
917a8f89 | 253 | Instead of using `.patch` as the suffix for generated |
02783075 | 254 | filenames, use specified suffix. A common alternative is |
50710ce4 SB |
255 | `--suffix=.txt`. Leaving this empty will remove the `.patch` |
256 | suffix. | |
03eeaeae | 257 | + |
50710ce4 SB |
258 | Note that the leading character does not have to be a dot; for example, |
259 | you can use `--suffix=-patch` to get `0001-description-of-my-change-patch`. | |
03eeaeae | 260 | |
b7df098c | 261 | -q:: |
b781cfaf CMN |
262 | --quiet:: |
263 | Do not print the names of the generated files to standard output. | |
264 | ||
37c22a4b | 265 | --no-binary:: |
50710ce4 SB |
266 | Do not output contents of changes in binary files, instead |
267 | display a notice that those files changed. Patches generated | |
268 | using this option cannot be applied properly, but they are | |
269 | still useful for code review. | |
37c22a4b | 270 | |
3a30aa17 | 271 | --zero-commit:: |
272 | Output an all-zero hash in each patch's From header instead | |
273 | of the hash of the commit. | |
274 | ||
fa2ab86d XY |
275 | --base=<commit>:: |
276 | Record the base tree information to identify the state the | |
277 | patch series applies to. See the BASE TREE INFORMATION section | |
278 | below for details. | |
279 | ||
2d266f9d TR |
280 | --root:: |
281 | Treat the revision argument as a <revision range>, even if it | |
282 | is just a single commit (that would normally be treated as a | |
283 | <since>). Note that root commits included in the specified | |
284 | range are always formatted as creation patches, independently | |
285 | of this flag. | |
286 | ||
738e88a2 KW |
287 | --progress:: |
288 | Show progress reports on stderr as patches are generated. | |

311 | DISCUSSION |
312 | ---------- | |
313 | ||
314 | The patch produced by 'git format-patch' is in UNIX mailbox format, | |
315 | with a fixed "magic" time stamp to indicate that the file is output | |
316 | from format-patch rather than a real mailbox, like so: | |
317 | ||

334 | ||
335 | Typically it will be placed in a MUA's drafts folder, edited to add | |
336 | timely commentary that should not go in the changelog after the three | |
337 | dashes, and then sent as a message whose body, in our example, starts | |
338 | with "arch/arm config files were...". On the receiving end, readers | |
339 | can save interesting patches in a UNIX mailbox and apply them with | |
340 | linkgit:git-am[1]. | |
341 | ||
342 | When a patch is part of an ongoing discussion, the patch generated by | |
343 | 'git format-patch' can be tweaked to take advantage of the 'git am | |
344 | --scissors' feature. After your response to the discussion comes a | |
345 | line that consists solely of "`-- >8 --`" (scissors and perforation), | |
346 | followed by the patch with unnecessary header fields removed: | |
347 | ||
348 | ------------ | |
349 | ... | |
350 | > So we should do such-and-such. | |

359 | ------------ | |
360 | ||
361 | When sending a patch this way, most often you are sending your own | |
362 | patch, so in addition to the "`From $SHA1 $magic_timestamp`" marker you | |
363 | should omit `From:` and `Date:` lines from the patch file. The patch | |
364 | title is likely to be different from the subject of the discussion the | |
365 | patch is in response to, so it is likely that you would want to keep | |
366 | the Subject: line, like the example above. | |

368 | Checking for patch corruption |
369 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
370 | Many mailers if not set up properly will corrupt whitespace. Here are | |
371 | two common types of corruption: | |
372 | ||
373 | * Empty context lines that do not have _any_ whitespace. | |
374 | ||
375 | * Non-empty context lines that have one extra whitespace at the | |
376 | beginning. | |
377 | ||
378 | One way to test if your MUA is set up correctly is: | |
379 | ||
380 | * Send the patch to yourself, exactly the way you would, except | |
381 | with To: and Cc: lines that do not contain the list and | |
382 | maintainer address. | |
383 | ||
384 | * Save that patch to a file in UNIX mailbox format. Call it a.patch, | |
385 | say. | |
386 | ||
387 | * Apply it: | |
388 | ||
389 | $ git fetch <project> master:test-apply | |
390 | $ git checkout test-apply | |
391 | $ git reset --hard | |
392 | $ git am a.patch | |
393 | ||
394 | If it does not apply correctly, there can be various reasons. | |
395 | ||
396 | * The patch itself does not apply cleanly. That is _bad_ but | |
397 | does not have much to do with your MUA. You might want to rebase | |
398 | the patch with linkgit:git-rebase[1] before regenerating it in | |
399 | this case. | |
400 | ||
401 | * The MUA corrupted your patch; "am" would complain that | |
402 | the patch does not apply. Look in the .git/rebase-apply/ subdirectory and | |
403 | see what 'patch' file contains and check for the common | |
404 | corruption patterns mentioned above. | |
405 | ||
406 | * While at it, check the 'info' and 'final-commit' files as well. | |
407 | If what is in 'final-commit' is not exactly what you would want to | |
408 | see in the commit log message, it is very likely that the | |
409 | receiver would end up hand editing the log message when applying | |
410 | your patch. Things like "Hi, this is my first patch.\n" in the | |
411 | patch e-mail should come after the three-dash line that signals | |
412 | the end of the commit message. | |

414 | MUA-SPECIFIC HINTS |
415 | ------------------ | |
416 | Here are some hints on how to successfully submit patches inline using | |
417 | various mailers. | |
418 | ||

419 | GMail |
420 | ~~~~~ | |
421 | GMail does not have any way to turn off line wrapping in the web | |
422 | interface, so it will mangle any emails that you send. You can however | |
423 | use "git send-email" and send your patches through the GMail SMTP server, or | |
424 | use any IMAP email client to connect to the google IMAP server and forward | |
425 | the emails through that. | |
426 | ||
427 | For hints on using 'git send-email' to send your patches through the | |
428 | GMail SMTP server, see the EXAMPLE section of linkgit:git-send-email[1]. | |
429 | ||
430 | For hints on submission using the IMAP interface, see the EXAMPLE | |
431 | section of linkgit:git-imap-send[1]. | |

433 | Thunderbird |
434 | ~~~~~~~~~~~ | |
435 | By default, Thunderbird will both wrap emails as well as flag | |
436 | them as being 'format=flowed', both of which will make the | |
2de9b711 | 437 | resulting email unusable by Git. |
dc53151f | 438 | |
b8959605 JS |
439 | There are three different approaches: use an add-on to turn off line wraps, |
440 | configure Thunderbird to not mangle patches, or use | |
dc53151f JN |
441 | an external editor to keep Thunderbird from mangling the patches. |
442 | ||
b8959605 JS |
443 | Approach #1 (add-on) |
444 | ^^^^^^^^^^^^^^^^^^^^ | |
445 | ||
446 | Install the Toggle Word Wrap add-on that is available from | |
447 | https://addons.mozilla.org/thunderbird/addon/toggle-word-wrap/ | |
448 | It adds a menu entry "Enable Word Wrap" in the composer's "Options" menu | |
449 | that you can tick off. Now you can compose the message as you otherwise do | |
450 | (cut + paste, 'git format-patch' | 'git imap-send', etc), but you have to | |
451 | insert line breaks manually in any text that you type. | |
452 | ||
453 | Approach #2 (configuration) | |
dc53151f JN |
454 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
455 | Three steps: | |
456 | ||
457 | 1. Configure your mail server composition as plain text: | |
458 | Edit...Account Settings...Composition & Addressing, | |
459 | uncheck "Compose Messages in HTML". | |
460 | ||
461 | 2. Configure your general composition window to not wrap. | |
462 | + | |
463 | In Thunderbird 2: | |
464 | Edit..Preferences..Composition, wrap plain text messages at 0 | |
465 | + | |
466 | In Thunderbird 3: | |
467 | Edit..Preferences..Advanced..Config Editor. Search for | |
468 | "mail.wrap_long_lines". | |
f737684d RJ |
469 | Toggle it to make sure it is set to `false`. Also, search for |
470 | "mailnews.wraplength" and set the value to 0. | |
dc53151f JN |
471 | |
472 | 3. Disable the use of format=flowed: | |
473 | Edit..Preferences..Advanced..Config Editor. Search for | |
474 | "mailnews.send_plaintext_flowed". | |
475 | Toggle it to make sure it is set to `false`. | |
476 | ||
477 | After that is done, you should be able to compose email as you | |
478 | otherwise would (cut + paste, 'git format-patch' | 'git imap-send', etc), | |
479 | and the patches will not be mangled. | |
480 | ||
b8959605 | 481 | Approach #3 (external editor) |
dc53151f JN |
482 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
483 | ||
484 | The following Thunderbird extensions are needed: | |
485 | AboutConfig from http://aboutconfig.mozdev.org/ and | |
486 | External Editor from http://globs.org/articles.php?lng=en&pg=8 | |
487 | ||
488 | 1. Prepare the patch as a text file using your method of choice. | |
489 | ||
490 | 2. Before opening a compose window, use Edit->Account Settings to | |
491 | uncheck the "Compose messages in HTML format" setting in the | |
492 | "Composition & Addressing" panel of the account to be used to | |
493 | send the patch. | |
494 | ||
495 | 3. In the main Thunderbird window, 'before' you open the compose | |
496 | window for the patch, use Tools->about:config to set the | |
497 | following to the indicated values: | |
498 | + | |
499 | ---------- | |
500 | mailnews.send_plaintext_flowed => false | |
501 | mailnews.wraplength => 0 | |
502 | ---------- | |
503 | ||
504 | 4. Open a compose window and click the external editor icon. | |
505 | ||
506 | 5. In the external editor window, read in the patch file and exit | |
507 | the editor normally. | |
508 | ||
509 | Side note: it may be possible to do step 2 with | |
510 | about:config and the following settings but no one's tried yet. | |
511 | ||
512 | ---------- | |
513 | mail.html_compose => false | |
514 | mail.identity.default.compose_html => false | |
515 | mail.identity.id?.compose_html => false | |
516 | ---------- | |
517 | ||
518 | There is a script in contrib/thunderbird-patch-inline which can help | |
519 | you include patches with Thunderbird in an easy way. To use it, do the | |
520 | steps above and then use the script as the external editor. | |
521 | ||
967ab8ef JN |
522 | KMail |
523 | ~~~~~ | |
524 | This should help you to submit patches inline using KMail. | |
525 | ||
526 | 1. Prepare the patch as a text file. | |
527 | ||
528 | 2. Click on New Mail. | |
529 | ||
530 | 3. Go under "Options" in the Composer window and be sure that | |
531 | "Word wrap" is not set. | |
532 | ||
533 | 4. Use Message -> Insert file... and insert the patch. | |
534 | ||
535 | 5. Back in the compose window: add whatever other text you wish to the | |
536 | message, complete the addressing and subject fields, and press send. | |

538 | BASE TREE INFORMATION |
539 | --------------------- | |
540 | ||
541 | The base tree information block is used for maintainers or third party | |
542 | testers to know the exact state the patch series applies to. It consists | |
543 | of the 'base commit', which is a well-known commit that is part of the | |
544 | stable part of the project history everybody else works off of, and zero | |
545 | or more 'prerequisite patches', which are well-known patches in flight | |
546 | that is not yet part of the 'base commit' that need to be applied on top | |
547 | of 'base commit' in topological order before the patches can be applied. | |
548 | ||
549 | The 'base commit' is shown as "base-commit: " followed by the 40-hex of | |
550 | the commit object name. A 'prerequisite patch' is shown as | |
551 | "prerequisite-patch-id: " followed by the 40-hex 'patch id', which can | |
552 | be obtained by passing the patch through the `git patch-id --stable` | |
553 | command. | |
554 | ||
555 | Imagine that on top of the public commit P, you applied well-known | |
556 | patches X, Y and Z from somebody else, and then built your three-patch | |
557 | series A, B, C, the history would be like: | |
558 | ||
559 | ................................................ | |
560 | ---P---X---Y---Z---A---B---C | |
561 | ................................................ | |
562 | ||
563 | With `git format-patch --base=P -3 C` (or variants thereof, e.g. with | |
7ba1ceef | 564 | `--cover-letter` or using `Z..C` instead of `-3 C` to specify the |
fa2ab86d XY |
565 | range), the base tree information block is shown at the end of the |
566 | first message the command outputs (either the first patch, or the | |
567 | cover letter), like this: | |
568 | ||
569 | ------------ | |
570 | base-commit: P | |
571 | prerequisite-patch-id: X | |
572 | prerequisite-patch-id: Y | |
573 | prerequisite-patch-id: Z | |
574 | ------------ | |
575 | ||
576 | For non-linear topology, such as | |
577 | ||
578 | ................................................ | |
579 | ---P---X---A---M---C | |
580 | \ / | |
581 | Y---Z---B | |
582 | ................................................ | |
583 | ||
584 | You can also use `git format-patch --base=P -3 C` to generate patches | |
585 | for A, B and C, and the identifiers for P, X, Y, Z are appended at the | |
586 | end of the first message. | |
e0d48279 | 587 | |
3de66517 XY |
588 | If set `--base=auto` in cmdline, it will track base commit automatically, |
589 | the base commit will be the merge base of tip commit of the remote-tracking | |
590 | branch and revision-range specified in cmdline. | |
591 | For a local branch, you need to track a remote branch by `git branch | |
592 | --set-upstream-to` before using this option. | |

594 | EXAMPLES |
595 | -------- | |
596 | ||
921177f5 | 597 | * Extract commits between revisions R1 and R2, and apply them on top of |
0b444cdb | 598 | the current branch using 'git am' to cherry-pick them: |
921177f5 CC |
599 | + |
600 | ------------ | |
467c0197 | 601 | $ git format-patch -k --stdout R1..R2 | git am -3 -k |
921177f5 CC |
602 | ------------ |
603 | ||
604 | * Extract all commits which are in the current branch but not in the | |
605 | origin branch: | |
606 | + | |
607 | ------------ | |
608 | $ git format-patch origin | |
609 | ------------ | |
610 | + | |
611 | For each commit a separate file is created in the current directory. | |
612 | ||
613 | * Extract all commits that lead to 'origin' since the inception of the | |
614 | project: | |
615 | + | |
616 | ------------ | |
9c67c757 | 617 | $ git format-patch --root origin |
921177f5 CC |
618 | ------------ |
619 | ||
620 | * The same as the previous one: | |
621 | + | |
622 | ------------ | |
623 | $ git format-patch -M -B origin | |
624 | ------------ | |
625 | + | |
626 | Additionally, it detects and handles renames and complete rewrites | |
627 | intelligently to produce a renaming patch. A renaming patch reduces | |
50710ce4 | 628 | the amount of text output, and generally makes it easier to review. |
2de9b711 TA |
629 | Note that non-Git "patch" programs won't understand renaming patches, so |
630 | use it only when you know the recipient uses Git to apply your patch. | |
921177f5 CC |
631 | |
632 | * Extract three topmost commits from the current branch and format them | |
633 | as e-mailable patches: | |
634 | + | |
635 | ------------ | |
636 | $ git format-patch -3 | |
637 | ------------ | |
