309
In non-recursive mode, all the named items are added, regardless
310
of whether they were previously ignored. A warning is given if
311
any of the named files are already versioned.
312
313
In recursive mode (the default), files are treated the same way
314
but the behaviour for directories is different. Directories that
315
are already versioned do not give a warning. All directories,
316
whether already versioned or not, are searched for files or
317
subdirectories that are neither versioned or ignored, and these
318
are added. This search proceeds recursively into versioned
319
directories. If no names are given '.' is assumed.
320
321
Therefore simply saying 'bzr add' will version all files that
322
are currently unknown.
323
324
Adding a file whose parent directory is not versioned will
325
implicitly add the parent, and so on up to the root. This means
326
you should never need to explicitly add a directory, they'll just
327
get added when you add a file in the directory.

--dry-run will show which files would be added, but not actually
330
add them.
331
332
--file-ids-from will try to use the file ids from the supplied path.
333
It looks up ids trying to find a matching parent directory with the
334
same filename, and then by pure path. This option is rarely needed
335
but can be useful when adding the same logical file into two
336
branches that will be merged later (without showing the two different
337
adds as a conflict). It is also useful when merging another project

If arguments are given, they are regular expressions that say which tests

2385
not run.
2386
2387
Alternatively if --first is given, matching tests are run first and then

all other tests are run. This is useful if you have been working in a

particular area, but want to make sure nothing else was broken.
2390
2391
If --exclude is given, tests that match that regular expression are
2392
excluded, regardless of whether they match --first or not.
2393
2394
To help catch accidential dependencies between tests, the --randomize
2395
option is useful. In most cases, the argument used is the word 'now'.
2396
Note that the seed used for the random number generator is displayed
2397
when this option is used. The seed can be explicitly passed as the
2398
argument to this option if required. This enables reproduction of the
2399
actual ordering used if and when an order sensitive problem is encountered.
2400
2401
If --list-only is given, the tests that would be run are listed. This is
2402
useful when combined with --first, --exclude and/or --randomize to

understand their impact. The test harness reports "Listed nn tests in ..."

instead of "Ran nn tests in ..." when list mode is enabled.

2570
2571
The branch is the branch you will merge from. By default, it will merge
2572
the latest revision. If you specify a revision, that revision will be
2573
merged. If you specify two revisions, the first will be used as a BASE,
2574
and the second one as OTHER. Revision numbers are always relative to the
2575
specified branch.
2576
2577
By default, bzr will try to merge in all new work from the other
2578
branch, automatically determining an appropriate base. If this
2579
fails, you may need to give an explicit base.
2580
2581
Merge will do its best to combine the changes in two branches, but there
2582
are some kinds of problems only a human can fix. When it encounters those,
2583
it will mark a conflict. A conflict means that you need to fix something,
2584
before you should commit.
2585
2586
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2587
2588
If there is no default branch set, the first merge will set it. After
2589
that, you can omit the branch to use the default. To change the
2590
default, use --remember. The value will only be saved if the remote
2591
location can be accessed.
2592
2593
The results of the merge are placed into the destination working
2594
directory, where they can be reviewed (with bzr diff), tested, and then
2595
committed to record the result of the merge.
2596
2597
Examples:
2598
2599
To merge the latest revision from bzr.dev:
2600
bzr merge ../bzr.dev
2601
2602
To merge changes up to and including revision 82 from bzr.dev:
2603
bzr merge -r 82 ../bzr.dev
2604
2605
To merge the changes introduced by 82, without previous changes:
2606
bzr merge -r 81..82 ../bzr.dev
2607
2608
merge refuses to run if there are any uncommitted changes, unless
2609
--force is given.
