DESCRIPTION
|
|
|
|
|
-----------
|
2010-01-09 23:33:00 +00:00
|
|
|
'git merge-file' incorporates all changes that lead from the `<base-file>`
|
2006-12-16 11:22:18 +00:00
|
|
|
to `<other-file>` into `<current-file>`. The result ordinarily goes into
|
2010-01-09 23:33:00 +00:00
|
|
|
`<current-file>`. 'git merge-file' is useful for combining separate changes
|
2006-12-16 11:22:18 +00:00
|
|
|
to an original. Suppose `<base-file>` is the original, and both
|
2008-12-09 06:23:51 +00:00
|
|
|
`<current-file>` and `<other-file>` are modifications of `<base-file>`,
|
2010-01-09 23:33:00 +00:00
|
|
|
then 'git merge-file' combines both changes.
|
2006-12-16 11:22:18 +00:00
|
|
|
|
|
|
|
|
A conflict occurs if both `<current-file>` and `<other-file>` have changes
|
2010-01-09 23:33:00 +00:00
|
|
|
in a common segment of lines. If a conflict is found, 'git merge-file'
|
2008-12-09 06:23:51 +00:00
|
|
|
normally outputs a warning and brackets the conflict with lines containing
|
|
|
|
|
<<<<<<< and >>>>>>> markers. A typical conflict will look like this:
|
2006-12-16 11:22:18 +00:00
|
|
|
|
|
|
|
|
<<<<<<< A
|
|
|
|
|
lines in file A
|
|
|
|
|
=======
|
|
|
|
|
lines in file B
|
|
|
|
|
>>>>>>> B
|
|
|
|
|
|
|
|
|
|
If there are conflicts, the user should edit the result and delete one of
|
2010-03-01 21:46:28 +00:00
|
|
|
the alternatives. When `--ours`, `--theirs`, or `--union` option is in effect,
|
|
|
|
|
however, these conflicts are resolved favouring lines from `<current-file>`,
|
|
|
|
|
lines from `<other-file>`, or lines from both respectively. The length of the
|
|
|
|
|
conflict markers can be given with the `--marker-size` option.
|

|

|

|
|
The exit value of this program is negative on error, and the number of
|
|
|
|
|
conflicts otherwise. If the merge was clean, the exit value is 0.

'git merge-file' is designed to be a minimal clone of RCS 'merge'; that is, it
|
2008-07-03 05:55:07 +00:00
|
|
|
implements all of RCS 'merge''s functionality which is needed by
|
2007-12-29 06:20:38 +00:00
|
|
|
linkgit:git[1].

OPTIONS
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
-L <label>::
|
|
|
|
|
This option may be given up to three times, and
|
|
|
|
|
specifies labels to be used in place of the
|
|
|
|
|
corresponding file names in conflict reports. That is,
|
2008-06-30 06:09:04 +00:00
|
|
|
`git merge-file -L x -L y -L z a b c` generates output that
|
2006-12-16 11:22:18 +00:00
|
|
|
looks like it came from files x, y and z instead of
|
|
|
|
|
from files a, b and c.
|
|
|
|
|
|
|
|
|
|
-p::
|
|
|
|
|
Send results to standard output instead of overwriting
|
|
|
|
|
`<current-file>`.
|
|
|
|
|
|
|
|
|
|
-q::
|
2008-12-09 06:23:51 +00:00
|
|
|
Quiet; do not warn about conflicts.
|

|
|
|
--union::
|
2008-06-20 07:17:27 +00:00
|
|
|
Instead of leaving conflicts in the file, resolve conflicts
|
2010-03-01 21:46:28 +00:00
|
|
|
favouring our (or their or both) side of the lines.

docs: put listed example commands in backticks
Many examples of git command invocation are given in asciidoc listing
blocks, which makes them monospaced and avoids further interpretation of
special characters. Some manpages make a list of examples, like:
git foo::
Run git foo.
git foo -q::
Use the "-q" option.
to quickly show many variants. However, they can sometimes be hard to
read, because they are shown in a proportional-width font (so, for
example, seeing the difference between "-- foo" and "--foo" can be
difficult).
This patch puts all such examples into backticks, which gives the
equivalent formatting to a listing block (i.e., monospaced and without
character interpretation).
As a bonus, this also fixes an example in the git-push manpage, in which
"git push origin :::" was accidentally considered a newly-indented list,
and not a list item with "git push origin :" in it.

tries to merge them and writes the result into README.my.
