As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near
future.

NAME

|
----
|
|
git-diff-tree - Compares the content and mode of blobs found via two tree objects
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-diff-tree' [--stdin] [-m] [-s] [-v] [--pretty] [-t] [<common diff options>] <tree-ish> <tree-ish> [<path>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Compares the content and mode of the blobs found via two tree objects.
|
|
|
|
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 these prefix strings.
|
|
ie file matches `/^<pattern1>|<pattern2>|.../`
|
|
Note that this parameter does not provide any wildcard or regexp
|
|
features.
|
|
|
|
-t::
|
|
show tree entry itself as well as subtrees. Implies -r.
|
|
|
|
--root::
|
|
When '--root' is specified the initial commit will be showed 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 either one <commit> or a pair of <tree-ish>
|
|
separated with a single space from its standard input.
|
|
+
|
|
When a single commit is given on one line of such input, it compares
|
|
the commit with its parents. The following flags further affects its
|
|
behaviour. This does not apply to the case where two <tree-ish>
|
|
separated with a single space are given.
|
|
|
|
-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.
|
|
|
|
-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 supressed. It is
|
|
only useful with '-v' flag.
|
|
|
|
-v::
|
|
This flag causes "git-diff-tree --stdin" to also show
|
|
the commit message before the differences.
|
|
|
|
--pretty[=(raw|medium|short)]::
|
|
This is used to control "pretty printing" format of the
|
|
commit message. Without "=<style>", it defaults to
|
|
medium.
|
|
|
|
|
|
Limiting Output
|
|
---------------
|
|
If you're only interested in differences in a subset of files, for
|
|
example some architecture-specific files, you might do:
|
|
|
|
git-diff-tree -r <tree-ish> <tree-ish> arch/ia64 include/asm-ia64
|
|
|
|
and it will only show you what changed in those two directories.
|
|
|
|
Or if you are searching for what changed in just `kernel/sched.c`, just do
|
|
|
|
git-diff-tree -r <tree-ish> <tree-ish> kernel/sched.c
|
|
|
|
and it will ignore all differences to other files.
|
|
|
|
The pattern is always the prefix, and is matched exactly. There are no
|
|
wildcards. Even stricter, it has to match a complete path component.
|
|
I.e. "foo" does not pick up `foobar.h`. "foo" does match `foo/bar.h`
|
|
so it can be used to name subdirectories.
|
|
|
|
An example of normal usage is:
|
|
|
|
torvalds@ppc970:~/git> git-diff-tree 5319e4......
|
|
*100664->100664 blob ac348b.......->a01513....... git-fsck-objects.c
|
|
|
|
which tells you that the last commit changed just one file (it's from
|
|
this one:
|
|
|
|
commit 3c6f7ca19ad4043e9e72fa94106f352897e651a8
|
|
tree 5319e4d609cdd282069cc4dce33c1db559539b03
|
|
parent b4e628ea30d5ab3606119d2ea5caeab141d38df7

|
|
|
|
Make "git-fsck-objects" print out all the root commits it finds.
|
|
|
|
Once I do the reference tracking, I'll also make it print out all the
|
|
HEAD commits it finds, which is even more interesting.
|
|
|
|
in case you care).
