Show differences in the working tree, between revisions or branches.
brz diff [FILE…]
- -c ARG, --change=ARG
Select changes introduced by the specified revision. See also “help revisionspec”.
Warn if trailing whitespace or spurious changes have been added.
Color mode to use. “always”: Always colorize output (default). “auto”: Only colorize output if terminal supports it and STDOUT is a TTY. “never”: Never colorize output.
How many lines of context to show.
Pass these options to the external diff program.
- -F ARG, --format=ARG
Diff format to use.
- -h, --help
Show help message.
Branch/tree to compare to.
Branch/tree to compare from.
- -p ARG, --prefix=ARG
Set prefixes added to old and new filenames, as two values separated by a colon. (eg “old/:new/”).
- -q, --quiet
Only display errors and warnings.
- -r ARG, --revision=ARG
See “help revisionspec” for details.
Show usage message and options.
Use this command to compare files.
- -v, --verbose
Display more information.
If no arguments are given, all changes for the current tree are listed. If files are given, only the changes in those files are listed. Remote and multiple branches can be compared by using the –old and –new options. If not provided, the default for both is derived from the first argument, if any, or the current tree if no arguments are given.
“brz diff -p1” is equivalent to “brz diff –prefix old/:new/”, and produces patches suitable for “patch -p1”.
Note that when using the -r argument with a range of revisions, the differences are computed between the two specified revisions. That is, the command does not show the changes introduced by the first revision in the range. This differs from the interpretation of revision ranges used by “brz log” which includes the first revision in the range.
- Exit values
1 - changed 2 - unrepresentable changes 3 - error 0 - no change
Shows the difference in the working tree versus the last commit:
Difference between the working tree and revision 1:
brz diff -r1
Difference between revision 3 and revision 1:
brz diff -r1..3
Difference between revision 3 and revision 1 for branch xxx:
brz diff -r1..3 xxx
The changes introduced by revision 2 (equivalent to -r1..2):
brz diff -c2
To see the changes introduced by revision X:
brz diff -cX
Note that in the case of a merge, the -c option shows the changes compared to the left hand parent. To see the changes against another parent, use:
brz diff -r<chosen_parent>..X
The changes between the current revision and the previous revision (equivalent to -c-1 and -r-2..-1)
brz diff -r-2..
Show just the differences for file NEWS:
brz diff NEWS
Show the differences in working tree xxx for file NEWS:
brz diff xxx/NEWS
Show the differences from branch xxx to this working tree:
brz diff –old xxx
Show the differences between two branches for file NEWS:
brz diff --old xxx --new yyy NEWS
Same as ‘brz diff’ but prefix paths with old/ and new/:
brz diff --prefix old/:new/
Show the differences using a custom diff program with options:
brz diff --using /usr/bin/diff --diff-options -wu
