git-diff-tree - Compares the content and mode of blobs found via two tree objects
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git diff-tree' [--stdin] [-m] [-s] [-v] [--no-commit-id] [--pretty]
|
|
[-t] [-r] [-c | --cc] [--combined-all-paths] [--root]
|
|
[<common diff options>] <tree-ish> [<tree-ish>] [<path>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Compares the content and mode of the blobs found via two tree objects.
|
|
|
|
If there is only one <tree-ish> given, the commit is compared with its parents
|
|
(see --stdin below).
|
|
|
|
Note that 'git diff-tree' can use the tree encapsulated in a commit object.
|
|
|
|
OPTIONS
|
|
-------
|
|
include::diff-options.txt[]
|
|
|
|
<tree-ish>::
|
|
The id of a tree object.
|
|
|
|
<path>...::
|
|
If provided, the results are limited to a subset of files
|
|
matching one of the provided pathspecs.
|
|
|
|
-r::
|
|
recurse into sub-trees
|
|
|
|
-t::
|
|
show tree entry itself as well as subtrees. Implies -r.
|
|
|
|
--root::
|
|
When `--root` is specified the initial commit will be shown as a big
|
|
creation event. This is equivalent to a diff against the NULL tree.
|
|
|
|
--stdin::
|
|
When `--stdin` is specified, the command does not take
|
|
<tree-ish> arguments from the command line. Instead, it
|
|
reads lines containing either two <tree>, one <commit>, or a
|
|
list of <commit> from its standard input. (Use a single space
|
|
as separator.)
|
|
+
|
|
When two trees are given, it compares the first tree with the second.
|
|
When a single commit is given, it compares the commit with its
|
|
parents. The remaining commits, when given, are used as if they are
|
|
parents of the first commit.
|
|
+
|
|
When comparing two trees, the ID of both trees (separated by a space
|
|
and terminated by a newline) is printed before the difference. When
|
|
comparing commits, the ID of the first (or only) commit, followed by a
|
|
newline, is printed.
|
|
+
|
|
The following flags further affect the behavior when comparing
|
|
commits (but not trees).
|
|
|
|
-m::
|
|
By default, 'git diff-tree --stdin' does not show
|
|
differences for merge commits. With this flag, it shows
|
|
differences to that commit from all of its parents. See
|
|
also `-c`.
|
|
|
|
-s::
|
|
By default, 'git diff-tree --stdin' shows differences,
|
|
either in machine-readable form (without `-p`) or in patch
|
|
form (with `-p`). This output can be suppressed. It is
|
|
only useful with `-v` flag.
|
|
|
|
-v::
|
|
This flag causes 'git diff-tree --stdin' to also show
|
|
the commit message before the differences.
|
|
|
|
include::pretty-options.txt[]
|
|
|
|
--no-commit-id::
|
|
'git diff-tree' outputs a line with the commit ID when
|
|
applicable. This flag suppressed the commit ID output.
|
|
|
|
-c::
|
|
This flag changes the way a merge commit is displayed
|
|
(which means it is useful only when the command is given
|
|
one <tree-ish>, or `--stdin`). It shows the differences
|
|
from each of the parents to the merge result simultaneously
|
|
instead of showing pairwise diff between a parent and the
|
|
result one at a time (which is what the `-m` option does).
|
|
Furthermore, it lists only files which were modified
|
|
from all parents.
|
|
|
|
--cc::
|
|
This flag changes the way a merge commit patch is displayed,
|
|
in a similar way to the `-c` option. It implies the `-c`
|
|
and `-p` options and further compresses the patch output
|
|
by omitting uninteresting hunks whose the contents in the parents
|
|
have only two variants and the merge result picks one of them
|
|
without modification. When all hunks are uninteresting, the commit
|
|
itself and the commit log message is not shown, just like in any other
|
|
"empty diff" case.
|
|
|
|
--combined-all-paths::
|
|
This flag causes combined diffs (used for merge commits) to
|
|
list the name of the file from all parents. It thus only has
|
|
effect when -c or --cc are specified, and is likely only
|
|
useful if filename changes are detected (i.e. when either
|
|
rename or copy detection have been requested).
|
|
|
|
--always::
|
|
Show the commit itself and the commit log message even
|
|
if the diff itself is empty.
