+ this (when '-c' option is used):
+
+ diff --combined file
++
+or like this (when '--cc' option is used):
+
+ diff --c file
+

+ mode <mode>,<mode>..<mode>

++
+The `mode <mode>,<mode>..<mode>` line appears only if at least one of

+information about detected contents movement (renames and

+Similar to two-line header for traditional 'unified' diff
+format, `/dev/null` is used to signal created or deleted
+files.
+
+4. Chunk header format is modified to prevent people from
+ accidentally feeding it to `patch -p1`. Combined diff format
+ was created for review of merge commit changes, and was not
+ meant for apply. The change is similar to the change in the
+ extended 'index' header:
+
+ @@@ <from-file-range> <from-file-range> <to-file-range> @@@
++
+There are (number of parents + 1) `@` characters in the chunk
+header for combined diff format.

Unlike the traditional 'unified' diff format, which shows two
files A and B with a single column that has `-` (minus --
appears in A but removed in B), `+` (plus -- missing in A but
-added to B), or ` ` (space -- unchanged) prefix, this format
+added to B), or `" "` (space -- unchanged) prefix, this format
compares two or more files file1, file2,... with one file X, and
shows how X differs from each of fileN. One column for each of
fileN is prepended to the output line to note how X's line is
different from it.
A `-` character in the column N means that the line appears in
-fileN but it does not appear in the last file. A `+` character

in the column N means that the line appears in the last file,

+'git-blame' [-c] [-l] [-t] [-f] [-n] [-p] [-S <revs-file>] [--] <file> [<rev>]
DESCRIPTION
-----------
-S, --rev-file <revs-file>::
Use revs from revs-file instead of calling gitlink:git-rev-list[1].
+-f, --show-name::
+ Show filename in the original commit. By default
+ filename is shown if there is any line that came from a
+ file with different name, due to rename detection.
+
+-n, --show-number::
+ Show line number in the original commit (Default: off).
+
+-p, --porcelain::
+ Show in a format designed for machine consumption.
+
-h, --help::
Show help message.
+THE PORCELAIN FORMAT
+--------------------
+
+In this format, each line is output after a header; the
+header at the minumum has the first line which has:
+
+- 40-byte SHA-1 of the commit the line is attributed to;
+- the line number of the line in the original file;
+- the line number of the line in the final file;
+- on a line that starts a group of line from a different
+ commit than the previous one, the number of lines in this
+ group. On subsequent lines this field is absent.
+
+This header line is followed by the following information
+at least once for each commit:
+
+- author name ("author"), email ("author-mail"), time
+ ("author-time"), and timezone ("author-tz"); similarly
+ for committer.
+- filename in the commit the line is attributed to.
+- the first line of the commit log message ("summary").
+
+The contents of the actual line is output after the above
+header, prefixed by a TAB. This is to allow adding more
+header elements later.

DESCRIPTION
-----------
The changeset (or "diff") of each commit between the fork-point and <head>

+Every commit that doesn't exist in the <upstream> branch
+has its id (sha1) reported, prefixed by a symbol. The ones that have

+
+ __*__*__*__*__> <upstream>
+ /
+ fork-point
+ \__*__*__<limit>__-__+__> <head>
+
Because git-cherry compares the changeset rather than the commit id
(sha1), you can use git-cherry to find out if a commit you made locally
This is ideally suited for read-only updates, i.e., pulling from
git repositories.
+An `upload-archive` also exists to serve `git-archive`.

+git-for-each-ref(1)
+===================
+
+NAME
+----
+git-for-each-ref - Output information on each ref
+
+SYNOPSIS
+--------
+'git-for-each-ref' [--count=<count>]\* [--shell|--perl|--python] [--sort=<key>]\* [--format=<format>] [<pattern>]
+
+DESCRIPTION
+-----------
+
+Iterate over all refs that match `<pattern>` and show them
+according to the given `<format>`, after sorting them according
+to the given set of `<key>`. If `<max>` is given, stop after
+showing that many refs. The interporated values in `<format>`
+can optionally be quoted as string literals in the specified
+host language allowing their direct evaluation in that language.
+
+OPTIONS
+-------
+<count>::
+ By default the command shows all refs that match
+ `<pattern>`. This option makes it stop after showing
+ that many refs.
+
+<key>::
+ A field name to sort on. Prefix `-` to sort in
+ descending order of the value. When unspecified,
+ `refname` is used. More than one sort keys can be
+ given.
+
+<format>::
+ A string that interpolates `%(fieldname)` from the
+ object pointed at by a ref being shown. If `fieldname`
+ is prefixed with an asterisk (`*`) and the ref points
+ at a tag object, the value for the field in the object
+ tag refers is used. When unspecified, defaults to
+ `%(objectname) SPC %(objecttype) TAB %(refname)`.
+ It also interpolates `%%` to `%`, and `%xx` where `xx`
+ are hex digits interpolates to character with hex code
+ `xx`; for example `%00` interpolates to `\0` (NUL),
+ `%09` to `\t` (TAB) and `%0a` to `\n` (LF).
+
+<pattern>::
+ If given, the name of the ref is matched against this
+ using fnmatch(3). Refs that do not match the pattern
+ are not shown.
+
+--shell, --perl, --python::
+ If given, strings that substitute `%(fieldname)`
+ placeholders are quoted as string literals suitable for
+ the specified host language. This is meant to produce
+ a scriptlet that can directly be `eval`ed.
+
+
+FIELD NAMES
+-----------
+
+Various values from structured fields in referenced objects can
+be used to interpolate into the resulting output, or as sort
+keys.
+
+For all objects, the following names can be used:
+
+refname::
+ The name of the ref (the part after $GIT_DIR/refs/).
+
+objecttype::
+ The type of the object (`blob`, `tree`, `commit`, `tag`).
+
+objectsize::
+ The size of the object (the same as `git-cat-file -s` reports).
+
+objectname::
+ The object name (aka SHA-1).
+
+In addition to the above, for commit and tag objects, the header
+field names (`tree`, `parent`, `object`, `type`, and `tag`) can
+be used to specify the value in the header field.
+
+Fields that have name-email-date tuple as its value (`author`,
+`committer`, and `tagger`) can be suffixed with `name`, `email`,
+and `date` to extract the named component.
+
+The first line of the message in a commit and tag object is
+`subject`, the remaining lines are `body`. The whole message
+is `contents`.
+
+For sorting purposes, fields with numeric values sort in numeric
+order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
+All other fields are used to sort in their byte-value order.
+
+In any case, a field name that refers to a field inapplicable to
+the object referred by the ref does not cause an error. It
+returns an empty string instead.
+
+
+EXAMPLES
+--------
+
+An example directly producing formatted text. Show the most recent
+3 tagged commits::
+
+------------
+#!/bin/sh
+
+git-for-each-ref --count=3 --sort='-*authordate' \
+--format='From: %(*authorname) %(*authoremail)
+Subject: %(*subject)
+Date: %(*authordate)
+Ref: %(*refname)
+
+%(*body)
+' 'refs/tags'
+------------
+
+
+A simple example showing the use of shell eval on the output,
+demonstrating the use of --shell. List the prefixes of all heads::
+------------
+#!/bin/sh
+
+git-for-each-ref --shell --format="ref=%(refname)" refs/heads | \
+while read entry
+do
+ eval "$entry"
+ echo `dirname $ref`
+done
+------------
+
+
+A bit more elaborate report on tags, demonstrating that the format
+may be an entire script::
+------------
+#!/bin/sh
+
+fmt='
+ r=%(refname)
+ t=%(*objecttype)
+ T=${r#refs/tags/}
+
+ o=%(*objectname)
+ n=%(*authorname)
+ e=%(*authoremail)
+ s=%(*subject)
+ d=%(*authordate)
+ b=%(*body)
+
+ kind=Tag
+ if test "z$t" = z
+ then
+ # could be a lightweight tag
+ t=%(objecttype)
+ kind="Lightweight tag"
+ o=%(objectname)
+ n=%(authorname)
+ e=%(authoremail)
+ s=%(subject)
+ d=%(authordate)
+ b=%(body)
+ fi
+ echo "$kind $T points at a $t object $o"
+ if test "z$t" = zcommit
+ then
+ echo "The commit was authored by $n $e
+at $d, and titled

+git-show-ref(1)
+===============
+
+NAME
+----
+git-show-ref - List references in a local repository
+
+SYNOPSIS
+--------
+[verse]
+'git-show-ref' [-q|--quiet] [--verify] [-h|--head] [-d|--dereference]
+ [-s|--hash] [--abbrev] [--tags] [--heads] [--] <pattern>...
+
+DESCRIPTION
+-----------
+
+Displays references available in a local repository along with the associated
+commit IDs. Results can be filtered using a pattern and tags can be
+dereferenced into object IDs. Additionally, it can be used to test whether a
+particular ref exists.
+
+Use of this utility is encouraged in favor of directly accessing files under
+in the `.git` directory.
+
+OPTIONS
+-------
+
+-h, --head::
+
+ Show the HEAD reference.
+
+--tags, --heads::
+
+ Limit to only "refs/heads" and "refs/tags", respectively. These
+ options are not mutually exclusive; when given both, references stored
+ in "refs/heads" and "refs/tags" are displayed.
+
+-d, --dereference::
+
+ Dereference tags into object IDs as well. They will be shown with "^{}"
+ appended.
+
+-s, --hash::
+
+ Only show the SHA1 hash, not the reference name. When also using
+ --dereference the dereferenced tag will still be shown after the SHA1.
+
+--verify::
+
+ Enable stricter reference checking by requiring an exact ref path.
+ Aside from returning an error code of 1, it will also print an error
+ message if '--quiet' was not specified.
+
+--abbrev, --abbrev=len::
+
+ Abbreviate the object name. When using `--hash`, you do
+ not have to say `--hash --abbrev`; `--hash=len` would do.
+
+-q, --quiet::
+
+ Do not print any results to stdout. When combined with '--verify' this
+ can be used to silently check if a reference exists.
+
+<pattern>::
+
+ Show references matching one or more patterns.
+
+OUTPUT
+------
+
+The output is in the format: '<SHA-1 ID>' '<space>' '<reference name>'.

+
+-----------------------------------------------------------------------------
+ git show-ref master
+-----------------------------------------------------------------------------
+
+This will show "refs/heads/master" but also "refs/remote/other-repo/master",
+if such references exists.
+
+When using the '--verify' flag, the command requires an exact path:
+
+-----------------------------------------------------------------------------
+ git show-ref --verify refs/heads/master
+-----------------------------------------------------------------------------
+
+will only match the exact branch called "master".
+
+If nothing matches, gitlink:git-show-ref[1] will return an error code of 1,
+and in the case of verification, it will show an error message.
+
+For scripting, you can ask it to be quiet with the "--quiet" flag, which
+allows you to do things like
+
+-----------------------------------------------------------------------------
+ git-show-ref --quiet --verify -- "refs/heads/$headname" ||
+ echo "$headname is not a valid branch"
+-----------------------------------------------------------------------------
+
+to check whether a particular branch exists or not (notice how we don't
+actually want to show any results, and we want to use the full refname for it
+in order to not trigger the problem with ambiguous partial matches).
+
+To show only tags, or only proper branch heads, use "--tags" and/or "--heads"
+respectively (using both means that it shows tags and heads, but not other
+random references under the refs/ subdirectory).
+
+To do automatic tag object dereferencing, use the "-d" or "--dereference"
+flag, so you can do
+
+-----------------------------------------------------------------------------
+ git show-ref --tags --dereference
+-----------------------------------------------------------------------------
+
+to get a listing of all tags together with what they dereference.

SYNOPSIS
--------
-'git-update-ref' [-m <reason>] <ref> <newvalue> [<oldvalue>]
+'git-update-ref' [-m <reason>] (-d <ref> <oldvalue> | <ref> <newvalue> [<oldvalue>])
DESCRIPTION
-----------
the current value of the <ref> matches <oldvalue>.
E.g. `git-update-ref refs/heads/master <newvalue> <oldvalue>`
updates the master branch head to <newvalue> only if its current
-value is <oldvalue>.
+value is <oldvalue>. You can specify 40 "0" or an empty string
+as <oldvalue> to make sure that the ref you are creating does
+not exist.
It also allows a "ref" file to be a symbolic pointer to another
ref file by starting with the four-byte header sequence of
ref symlink to some other tree, if you have copied a whole
archive by creating a symlink tree).
+With `-d` flag, it deletes the named <ref> after verifying it
+still contains <oldvalue>.
+
+
Logging Updates
---------------
If config parameter "core.logAllRefUpdates" is true or the file
We divide git into high level ("porcelain") commands and low level
("plumbing") commands.
-Low-level commands (plumbing)
------------------------------
-
-Although git includes its
-own porcelain layer, its low-level commands are sufficient to support
-development of alternative porcelains. Developers of such porcelains
-might start by reading about gitlink:git-update-index[1] and
-gitlink:git-read-tree[1].
-
-We divide the low-level commands into commands that manipulate objects (in
-the repository, index, and working tree), commands that interrogate and
-compare objects, and commands that move objects and references between
-repositories.
-
