core.logAllRefUpdates::
- If true, `git-update-ref` will append a line to
- "$GIT_DIR/logs/<ref>" listing the new SHA1 and the date/time
- of the update. If the file does not exist it will be
- created automatically. This information can be used to
- determine what commit was the tip of a branch "2 days ago".
- This value is false by default (no logging).
+ Updates to a ref <ref> is logged to the file
+ "$GIT_DIR/logs/<ref>", by appending the new and old
+ SHA1, the date/time and the reason of the update, but
+ only when the file exists. If this configuration
+ variable is set to true, missing "$GIT_DIR/logs/<ref>"
+ file is automatically created for branch heads.
+
+ This information can be used to determine what commit
+ was the tip of a branch "2 days ago". This value is
+ false by default (no automated creation of log files).
core.repositoryFormatVersion::
Internal variable identifying the repository format and layout
The default set of "refspec" for gitlink:git-push[1]. See
gitlink:git-push[1].
+repack.usedeltabaseoffset::
+ Allow gitlink:git-repack[1] to create packs that uses
+ delta-base offset. Defaults to false.
+
show.difftree::
The default gitlink:git-diff-tree[1] arguments to be used
for gitlink:git-show[1].
The width of the filename part can be controlled by
giving another width to it separated by a comma.

SYNOPSIS
--------
-'git-blame' [-c] [-l] [-t] [-S <revs-file>] [--] <file> [<rev>]
+'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.

+===================
+
+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
+
+ $s
+
+Its message reads as:
+"
+ echo "$b" | sed -e "s/^/ /"
+ echo
+ fi
+'
+
+eval=`git-for-each-ref --shell --format="$fmt" \
+ --sort='*objecttype' \
+ --sort=-taggerdate \
+ refs/tags`

SYNOPSIS
--------
[verse]
-'git-pack-objects' [-q] [--no-reuse-delta] [--non-empty]
+'git-pack-objects' [-q] [--no-reuse-delta] [--delta-base-offset] [--non-empty]
[--local] [--incremental] [--window=N] [--depth=N]
[--revs [--unpacked | --all]*] [--stdout | base-name] < object-list
This flag tells the command not to reuse existing deltas
but compute them from scratch.
+--delta-base-offset::
+ A packed archive can express base object of a delta as
+ either 20-byte object name or as an offset in the
+ stream, but older version of git does not understand the
+ latter. By default, git-pack-objects only uses the
+ former format for better compatibility. This option
+ allows the command to use the latter format for
+ compactness. Depending on the average delta chain
+ length, this option typically shrinks the resulting
+ packfile by 3-5 per-cent.

NOTES
The default value for both --window and --depth is 10.
+Configuration
+-------------
+
+When configuration variable `repack.UseDeltaBaseOffset` is set
+for the repository, the command passes `--delta-base-offset`
+option to `git-pack-objects`; this typically results in slightly
+smaller packs, but the generated packs are incompatible with
+versions of git older than (and including) v1.4.3; do not set
+the variable in a repository that older version of git needs to
+be able to read (this includes repositories from which packs can
+be copied out over http or rsync, and people who obtained packs
+that way can try to use older git with it).

+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 --head --dereference
+832e76a9899f560a90ffd62ae2ce83bbeff58f54 HEAD

+...
+-----------------------------------------------------------------------------
+
+When using --hash (and not --dereference) the output format is: '<SHA-1 ID>'
+
+-----------------------------------------------------------------------------
+$ git show-ref --heads --hash
+2e3ba0114a1f52b47df29743d6915d056be13278

+03adf42c988195b50e1a1935ba5fcbc39b2b029b
+...
+-----------------------------------------------------------------------------
+
+EXAMPLE
+-------
+
+To show all references called "master", whether tags or heads or anything
+else, and regardless of how deep in the reference naming hierarchy they are,
+use:
+
+-----------------------------------------------------------------------------
+ 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.

-'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.

+
+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.
+
+Manipulation commands
+~~~~~~~~~~~~~~~~~~~~~
+gitlink:git-apply[1]::
+ Reads a "diff -up1" or git generated patch file and
+ applies it to the working tree.

+ Unpacks objects out of a packed archive.
+
+gitlink:git-update-index[1]::
+ Registers files in the working tree to the index.
+
+gitlink:git-write-tree[1]::
+ Creates a tree from the index.
+
+
+Interrogation commands
+~~~~~~~~~~~~~~~~~~~~~~
+
+gitlink:git-cat-file[1]::
+ Provide content or type/size information for repository objects.
+
+gitlink:git-describe[1]::
+ Show the most recent tag that is reachable from a commit.
+
+gitlink:git-diff-index[1]::
+ Compares content and mode of blobs between the index and repository.
+
+gitlink:git-diff-files[1]::
+ Compares files in the working tree and the index.

+ This file will be loaded using 'require' and can be used to override any
+ of the options above as well as some other options - see the top of
+ 'gitweb.cgi' for their full list and description. If the environment
$GITWEB_CONFIG is set when gitweb.cgi is executed the file in the
environment variable will be loaded instead of the file
specified when gitweb.cgi was created.
+Runtime gitweb configuration
+----------------------------
+
+You can adjust gitweb behaviour using the file specified in `GITWEB_CONFIG`
+(defaults to 'gitweb_config.perl' in the same directory as the CGI).
+See the top of 'gitweb.cgi' for the list of variables and some description.
+The most notable thing that is not configurable at compile time are the
+optional features, stored in the '%features' variable. You can find further
+description on how to reconfigure the default features setting in your
+`GITWEB_CONFIG` or per-project in `project.git/config` inside 'gitweb.cgi'.
