+ [-M] [-C] [-C] [--since=<date>] [<rev>] [--] <file>
DESCRIPTION
-----------
Annotates each line in the given file with information from the revision which
last modified the line. Optionally, start annotating from the given revision.
+Also it can limit the range of lines annotated.
+
This report doesn't tell you anything about lines which have been deleted or
replaced; you need to use a tool such as gitlink:git-diff[1] or the "pickaxe"
interface briefly mentioned in the following paragraph.
-c, --compatibility::
Use the same output mode as gitlink:git-annotate[1] (Default: off).
+-L n,m::
+ Annotate only the specified line range (lines count from 1).
+
-l, --long::
Show long rev (Default: off).
-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.
+
+-M::
+ Detect moving lines in the file as well. When a commit
+ moves a block of lines in a file (e.g. the original file
+ has A and then B, and the commit changes it to B and
+ then A), traditional 'blame' algorithm typically blames
+ the lines that were moved up (i.e. B) to the parent and
+ assigns blame to the lines that were moved down (i.e. A)
+ to the child commit. With this option, both groups of
+ lines are blamed on the parent.
+
+-C::
+ In addition to `-M`, detect lines copied from other
+ files that were modified in the same commit. This is
+ useful when you reorganize your program and move code
+ around across files. When this option is given twice,
+ the command looks for copies from all other files in the
+ parent for the commit that creates the file in addition.
+
-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.
+
+
+SPECIFIYING RANGES
+------------------
+
+Unlike `git-blame` and `git-annotate` in older git, the extent
+of annotation can be limited to both line ranges and revision
+ranges. When you are interested in finding the origin for
+ll. 40-60 for file `foo`, you can use `-L` option like this:
+
+ git blame -L 40,60 foo
+
+Also you can use regular expression to specify the line range.
+
+ git blame -L '/^sub hello {/,/^}$/' foo
+
+would limit the annotation to the body of `hello` subroutine.
+
+When you are not interested in changes older than the version
+v2.6.18, or changes older than 3 weeks, you can use revision
+range specifiers similar to `git-rev-list`:
+
+ git blame v2.6.18.. -- foo
+ git blame --since=3.weeks -- foo
+
+When revision range specifiers are used to limit the annotation,
+lines that have not changed since the range boundary (either the
+commit v2.6.18 or the most recent commit that is more than 3
+weeks old in the above example) are blamed for that range
+boundary commit.
+
+A particularly useful way is to see if an added file have lines
+created by copy-and-paste from existing files. Sometimes this
+indicates that the developer was being sloppy and did not
+refactor the code properly. You can first find the commit that
+introduced the file with:
+
+ git log --diff-filter=A --pretty=short -- foo
+
+and then annotate the change between the commit and its
+parents, using `commit{caret}!` notation:
+
+ git blame -C -C -f $commit^! -- foo
+
+

+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" \

+'git-index-pack' [-v] [-o <index-file>] <pack-file>
+'git-index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>] [<pack-file>]
DESCRIPTION
OPTIONS
-------
+-v::
+ Be verbose about what is going on, including progress status.
+
-o <index-file>::
Write the generated pack index into the specified
file. Without this option the name of pack index
fails if the name of packed archive does not end
with .pack).
+--stdin::
+ When this flag is provided, the pack is read from stdin
+ instead and a copy is then written to <pack-file>. If
+ <pack-file> is not specified, the pack is written to
+ objects/pack/ directory of the current git repository with
+ a default name determined from the pack content. If
+ <pack-file> is not specified consider using --keep to
+ prevent a race condition between this process and
+ gitlink::git-repack[1] .
+
+--fix-thin::
+ It is possible for gitlink:git-pack-objects[1] to build
+ "thin" pack, which records objects in deltified form based on
+ objects not included in the pack to reduce network traffic.
+ Those objects are expected to be present on the receiving end
+ and they must be included in the pack for that pack to be self
+ contained and indexable. Without this option any attempt to
+ index a thin pack will fail. This option only makes sense in
+ conjunction with --stdin.
+
+--keep::
+ Before moving the index into its final destination
+ create an empty .keep file for the associated pack file.
+ This option is usually necessary with --stdin to prevent a
+ simultaneous gitlink:git-repack[1] process from deleting
+ the newly constructed pack and index before refs can be
+ updated to use objects contained in the pack.
+
+--keep='why'::
+ Like --keep create a .keep file before moving the index into
+ its final destination, but rather than creating an empty file
+ place 'why' followed by an LF into the .keep file. The 'why'
+ message can later be searched for within all .keep files to
+ locate any which have outlived their usefulness.
+
+
+Note
+----
+
+Once the index has been created, the list of object names is sorted
+and the SHA1 hash of that list is printed to stdout. If --stdin was
+also used then this is prefixed by either "pack\t", or "keep\t" if a
+new .keep file was successfully created. This is useful to remove a
+.keep file used as a lock to prevent the race with gitlink:git-repack[1]
+mentioned above.

+'git-pack-objects' [-q] [--no-reuse-delta] [--delta-base-offset] [--non-empty]
+ [--local] [--incremental] [--window=N] [--depth=N] [--all-progress]
[--revs [--unpacked | --all]*] [--stdout | base-name] < object-list
Only create a packed archive if it would contain at
least one object.
+--progress::
+ Progress status is reported on the standard error stream
+ by default when it is attached to a terminal, unless -q
+ is specified. This flag forces progress status even if
+ the standard error stream is not directed to a terminal.
+
+--all-progress::
+ When --stdout is specified then progress report is
+ displayed during the object count and deltification phases
+ but inhibited during the write-out phase. The reason is
+ that in some cases the output stream is directly linked
+ to another command which may wish to display progress
+ status of its own as it processes incoming pack data.
+ This flag is like --progress except that it forces progress
+ report for the write-out phase as well even if --stdout is
+ used.
+
-q::
This flag makes the command not to report its progress
on the standard error stream.
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.

+================
+
+NAME
+----
+git-pack-refs - Pack heads and tags for efficient repository access
+
+SYNOPSIS
+--------
+'git-pack-refs' [--all] [--prune]
+
+DESCRIPTION
+-----------
+
+Traditionally, tips of branches and tags (collectively known as
+'refs') were stored one file per ref under `$GIT_DIR/refs`
+directory. While many branch tips tend to be updated often,
+most tags and some branch tips are never updated. When a
+repository has hundreds or thousands of tags, this
+one-file-per-ref format both wastes storage and hurts
+performance.
+
+This command is used to solve the storage and performance
+problem by stashing the refs in a single file,
+`$GIT_DIR/packed-refs`. When a ref is missing from the
+traditional `$GIT_DIR/refs` hierarchy, it is looked up in this
+file and used if found.
+
+Subsequent updates to branches always creates new file under
+`$GIT_DIR/refs` hierarchy.
+
+OPTIONS
+-------
+
+\--all::
+
+The command by default packs all tags and leaves branch tips
+alone. This is because branches are expected to be actively
+developed and packing their tips does not help performance.
+This option causes branch tips to be packed as well. Useful for
+a repository with many branches of historical interests.
+
+\--prune::
+
+After packing the refs, remove loose refs under `$GIT_DIR/refs`
+hierarchy. This should probably become default.

+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).

+DESCRIPTION
+-----------
+
+Displays references available in a local repository along with the associated

+
+--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.

+ 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>'.

+-----------------------------------------------------------------------------
+
+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.

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.

- This file will be loaded using 'require'. If the environment
+ 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'.
