For shell scripts specifically (not exhaustive):
+ - We use tabs for indentation.
+
+ - Case arms are indented at the same depth as case and esac lines.
+
- We prefer $( ... ) for command substitution; unlike ``, it
properly nests. It should have been the way Bourne spelled
it from day one, but unfortunately isn't.
- When we pass <string, length> pair to functions, we should try to
pass them in that order.
+
+Writing Documentation:
+
+ Every user-visible change should be reflected in the documentation.
+ The same general rule as for code applies -- imitate the existing
+ conventions. A few commented examples follow to provide reference
+ when writing or modifying command usage strings and synopsis sections
+ in the manual pages:
+
+ Placeholders are enclosed in angle brackets:
+ <file>
+ --sort=<key>
+ --abbrev[=<n>]
+
+ Possibility of multiple occurences is indicated by three dots:
+ <file>...
+ (One or more of <file>.)
+
+ Optional parts are enclosed in square brackets:
+ [<extra>]
+ (Zero or one <extra>.)
+
+ --exec-path[=<path>]
+ (Option with an optional argument. Note that the "=" is inside the
+ brackets.)
+
+ [<patch>...]
+ (Zero or more of <patch>. Note that the dots are inside, not
+ outside the brackets.)
+
+ Multiple alternatives are indicated with vertical bar:
+ [-q | --quiet]
+ [--utf8 | --no-utf8]
+
+ Parentheses are used for grouping:
+ [(<rev>|<range>)...]
+ (Any number of either <rev> or <range>. Parens are needed to make
+ it clear that "..." pertains to both <rev> and <range>.)
+
+ [(-p <parent>)...]
+ (Any number of option -p, each with one <parent> argument.)
+
+ git remote set-head <name> (-a | -d | <branch>)
+ (One and only one of "-a", "-d" or "<branch>" _must_ (no square
+ brackets) be provided.)
+
+ And a somewhat more contrived example:
+ --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
+ Here "=" is outside the brackets, because "--diff-filter=" is a
+ valid usage. "*" has its own pair of brackets, because it can
+ (optionally) be specified only when one or more of the letters is
+ also provided.

+
+ * Highlighting of whitespace breakage in "diff" output was showing
+ incorrect amount of whitespaces when blank-at-eol is set and the line
+ consisted only of whitespaces and a TAB.
+
+ * "diff" was overly inefficient when trying to find the line to use for
+ the function header (i.e. equivalent to --show-c-function of GNU diff).
+
+ * "git imap-send" depends on libcrypto but our build rule relied on the

+
+ * "git merge-file" can be called from within a subdirectory now.
+
+ * "git repack -f" expanded and recompressed non-delta objects in the

+ want to (e.g. when changing the pack.compression level).
+
+ * "git rev-list --format="...%x00..." incorrectly chopped its output

+==========================
+
+Fixes since v1.7.3.3
+--------------------
+
+ * Smart HTTP transport used to incorrectly retry redirected POST
+ request with GET request.
+
+ * "git apply" did not correctly handle patches that only change modes
+ if told to apply while stripping leading paths with -p option.
+
+ * "git apply" can deal with patches with timezone formatted with a
+ colon between the hours and minutes part (e.g. "-08:00" instead of
+ "-0800").
+
+ * "git cherry-pick" or "git revert" refused to work when a path that
+ would be modified by the operation was stat-dirty without a real
+ difference in the contents of the file.
+
+ * "git diff --check" reported an incorrect line number for added
+ blank lines at the end of file.
+
+ * Setting log.decorate configuration variable to "0" or "1" to mean
+ "false" or "true" did not work.
+
+ * "git tag -v" did not work with GPG signatures in rfc1991 mode.
+
+ * The post-receive-email sample hook was accidentally broken in 1.7.3.3
+ update.
+
+Other minor fixes and documentation updates are also included.
/etc/gitattributes; core.attributesfile configuration variable can
be used to customize the path to this file.
+ * The thread structure generated by "git send-email" has changed
+ slightly. Setting the cover letter of the latest series as a reply
+ to the cover letter of the previous series with --in-reply-to used
+ to make the new cover letter and all the patches replies to the
+ cover letter of the previous series; this has been changed to make
+ the patches in the new series replies to the new cover letter.
+
* Bash completion script in contrib/ has been adjusted to be also
usable by zsh.
+ * "git blame" learned --show-email option to display the e-mail
+ addresses instead of the names of authors.
+
+ * "git daemon" can be built in MinGW environment.
+
* "git daemon" can take more than one --listen option to listen to
multiple addresses.
* "git merge --log" used to limit the resulting merge log to 20
entries; this is now customizable by giving e.g. "--log=47".
+ * "git merge" may work better when all files were moved out of a
+ directory in one branch while a new file is created in place of that
+ directory in the other branch.
+
+ * "git rebase --autosquash" can use SHA-1 object names to name which
+ commit to fix up (e.g. "fixup! e83c5163").
+
* The default "recursive" merge strategy learned --rename-threshold
option to influence the rename detection, similar to the -M option
of "git diff". E.g. "git merge -Xrename-threshold=50% ..." to use
All of the fixes in v1.7.3.X maintenance series are included in this
release, unless otherwise noted.
- * "diff" and friends incorrectly applied textconv filters to symlinks

+ tree when switching to a branch that contains a tracked path
+ "foo/bar". Prevent this, just like the case where the conflicting
+ path were "foo" (c752e7f..7980872d).
* "git log --author=me --author=her" did not find commits written by
me or by her; instead it looked for commits written by me and by
her, which is impossible.
- * "git merge-file" can be called from within a subdirectory now
- (55846b9a).
+ * "git merge" into an unborn branch removed an untracked file "foo"
+ from the working tree when merged branch had "foo" (2caf20c..172b642).
* "git push --progress" shows progress indicators now.
* "git repack" places its temporary packs under $GIT_OBJECT_DIRECTORY/pack
instead of $GIT_OBJECT_DIRECTORY/ to avoid cross directory renames.
- * "git rev-list --format="...%x00..." incorrectly chopped its output
- at NUL (9130ac9fe).

DESCRIPTION
-----------
historical reasons. Do not use it from the command line or in
new scripts. It is the same as `git merge -m <msg> <commit>...`.
+The third syntax ("`git merge --abort`") can only be run after the
+merge has resulted in conflicts. 'git merge --abort' will abort the
+merge process and try to reconstruct the pre-merge state. However,
+if there were uncommitted changes when the merge started (and
+especially if those changes were further modified after the merge
+was started), 'git merge --abort' will in some cases be unable to
+reconstruct the original (pre-merge) changes. Therefore:
+
*Warning*: Running 'git merge' with uncommitted changes is
discouraged: while possible, it leaves you in a state that is hard to
back out of in the case of a conflict.
Allow the rerere mechanism to update the index with the
result of auto-conflict resolution if possible.
+--abort::
+ Abort the current conflict resolution process, and
+ try to reconstruct the pre-merge state.
++
+If there were uncommitted worktree changes present when the merge
+started, 'git merge --abort' will in some cases be unable to
+reconstruct these changes. It is therefore recommended to always
+commit or stash your changes before running 'git merge'.
++
+'git merge --abort' is equivalent to 'git reset --merge' when
+`MERGE_HEAD` is present.
+
<commit>...::
Commits, usually other branch heads, to merge into our branch.
You need at least one <commit>. Specifying more than one
i.e. matching `HEAD`.
If you tried a merge which resulted in complex conflicts and
-want to start over, you can recover with `git reset --merge`.

HOW CONFLICTS ARE PRESENTED
---------------------------
* Decide not to merge. The only clean-ups you need are to reset
the index file to the `HEAD` commit to reverse 2. and to clean
- up working tree changes made by 2. and 3.; `git-reset --hard` can
- be used for this.
+ up working tree changes made by 2. and 3.; `git merge --abort`
+ can be used for this.
* Resolve the conflicts. Git will mark the conflicts in
the working tree. Edit the files into shape and
'git notes' append [-F <file> | -m <msg> | (-c | -C) <object>] [<object>]
'git notes' edit [<object>]
'git notes' show [<object>]
+'git notes' merge [-v | -q] [-s <strategy> ] <notes_ref>
+'git notes' merge --commit [-v | -q]
+'git notes' merge --abort [-v | -q]
'git notes' remove [<object>]
'git notes' prune [-n | -v]
+'git notes' get-ref
DESCRIPTION
show::
Show the notes for a given object (defaults to HEAD).
+merge::
+ Merge the given notes ref into the current notes ref.
+ This will try to merge the changes made by the given
+ notes ref (called "remote") since the merge-base (if
+ any) into the current notes ref (called "local").
++
+If conflicts arise and a strategy for automatically resolving
+conflicting notes (see the -s/--strategy option) is not given,
+the "manual" resolver is used. This resolver checks out the
+conflicting notes in a special worktree (`.git/NOTES_MERGE_WORKTREE`),
+and instructs the user to manually resolve the conflicts there.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
remove::
Remove the notes for a given object (defaults to HEAD).
This is equivalent to specifying an empty note message to
prune::
Remove all notes for non-existing/unreachable objects.
+get-ref::
+ Print the current notes ref. This provides an easy way to
+ retrieve the current notes ref (e.g. from scripts).
+
OPTIONS
-------
-f::
Do not remove anything; just report the object names whose notes
would be removed.
+-s <strategy>::
+--strategy=<strategy>::
+ When merging notes, resolve notes conflicts using the given
+ strategy. The following strategies are recognized: "manual"
+ (default), "ours", "theirs", "union" and "cat_sort_uniq".
+ See the "NOTES MERGE STRATEGIES" section below for more
+ information on each notes merge strategy.
+
+--commit::
+ Finalize an in-progress 'git notes merge'. Use this option
+ when you have resolved the conflicts that 'git notes merge'
+ stored in .git/NOTES_MERGE_WORKTREE. This amends the partial
+ merge commit created by 'git notes merge' (stored in
+ .git/NOTES_MERGE_PARTIAL) by adding the notes in
+ .git/NOTES_MERGE_WORKTREE. The notes ref stored in the
+ .git/NOTES_MERGE_REF symref is updated to the resulting commit.
+
+--abort::
+ Abort/reset a in-progress 'git notes merge', i.e. a notes merge
+ with conflicts. This simply removes all files related to the
+ notes merge.
+
+-q::
+--quiet::
+ When merging notes, operate quietly.
+
-v::
--verbose::
- Report all object names whose notes are removed.

+ removed.
DISCUSSION
`git log -p -g <refname>`.
+NOTES MERGE STRATEGIES
+----------------------
+
+The default notes merge strategy is "manual", which checks out
+conflicting notes in a special work tree for resolving notes conflicts
+(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
+conflicts in that work tree.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+"ours" automatically resolves conflicting notes in favor of the local
+version (i.e. the current notes ref).
+
+"theirs" automatically resolves notes conflicts in favor of the remote
+version (i.e. the given notes ref being merged into the current notes
+ref).
+
+"union" automatically resolves notes conflicts by concatenating the
+local and remote versions.
+
+"cat_sort_uniq" is similar to "union", but in addition to concatenating
+the local and remote versions, this strategy also sorts the resulting
+lines, and removes duplicate lines from the result. This is equivalent
+to applying the "cat | sort | uniq" shell pipeline to the local and
+remote versions. This strategy is useful if the notes follow a line-based
+format where one wants to avoid duplicated lines in the merge result.
+Note that if either the local or remote version contain duplicate lines
+prior to the merge, these will also be removed by this notes merge
+strategy.
+

+git-remote-ext(1)
+=================
+
+NAME
+----
+git-remote-ext - Bridge smart transport to external command.
+
+SYNOPSIS
+--------
+git remote add nick "ext::<command>[ <arguments>...]"
+
+DESCRIPTION
+-----------
+This remote helper uses the specified 'program' to connect
+to a remote git server.
+
+Data written to stdin of this specified 'program' is assumed
+to be sent to git:// server, git-upload-pack, git-receive-pack
+or git-upload-archive (depending on situation), and data read
+from stdout of this program is assumed to be received from
+the same service.
+
+Command and arguments are separated by unescaped space.
+
+The following sequences have a special meaning:
+
+'% '::
+ Literal space in command or argument.
+
+'%%'::
+ Literal percent sign.
+
+'%s'::
+ Replaced with name (receive-pack, upload-pack, or
+ upload-archive) of the service git wants to invoke.
+
+'%S'::
+ Replaced with long name (git-receive-pack,
+ git-upload-pack, or git-upload-archive) of the service
+ git wants to invoke.
+
+'%G' (must be first characters in argument)::
+ This argument will not be passed to 'program'. Instead, it
+ will cause helper to start by sending git:// service request to
+ remote side with service field set to approiate value and
+ repository field set to rest of the argument. Default is not to send
+ such request.
++
+This is useful if remote side is git:// server accessed over
+some tunnel.
+
+'%V' (must be first characters in argument)::
+ This argument will not be passed to 'program'. Instead it sets
+ the vhost field in git:// service request (to rest of the argument).
+ Default is not to send vhost in such request (if sent).
+
+ENVIRONMENT VARIABLES:
+----------------------
+
+GIT_TRANSLOOP_DEBUG::
+ If set, prints debugging information about various reads/writes.
+
+ENVIRONMENT VARIABLES PASSED TO COMMAND:
+----------------------------------------
+
+GIT_EXT_SERVICE::
+ Set to long name (git-upload-pack, etc...) of service helper needs
+ to invoke.
+
+GIT_EXT_SERVICE_NOPREFIX::
+ Set to long name (upload-pack, etc...) of service helper needs
+ to invoke.
+
+
+EXAMPLES:
+---------
+This remote helper is transparently used by git when
+you use commands such as "git fetch <URL>", "git clone <URL>",
+, "git push <URL>" or "git remote add nick <URL>", where <URL>
+begins with `ext::`. Examples:
+
+"ext::ssh -i /home/foo/.ssh/somekey user@host.example %S 'foo/repo'"::
+ Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
+ keypair and user as user on remote side. This avoids needing to
+ edit .ssh/config.
+
+"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
+ Represents repository with path /somerepo accessable over
+ git protocol at abstract namespace address /git-server.
+
+"ext::git-server-alias foo %G/repo"::
+ Represents a repository with path /repo accessed using the
+ helper program "git-server-alias foo". The path to the
+ repository and type of request are not passed on the command
+ line but as part of the protocol stream, as usual with git://
+ protocol.
+
+"ext::git-server-alias foo %G/repo %Vfoo"::
+ Represents a repository with path /repo accessed using the

+================
+
+NAME
+----
+git-remote-fd - Reflect smart transport stream back to caller
+
+SYNOPSIS
+--------
+"fd::<infd>[,<outfd>][/<anything>]" (as URL)
+
+DESCRIPTION
+-----------
+This helper uses specified file descriptors to connect to remote git server.
+This is not meant for end users but for programs and scripts calling git
+fetch, push or archive.
+
+If only <infd> is given, it is assumed to be bidirectional socket connected
+to remote git server (git-upload-pack, git-receive-pack or
+git-upload-achive). If both <infd> and <outfd> are given, they are assumed
+to be pipes connected to remote git server (<infd> being the inbound pipe
+and <outfd> being the outbound pipe.
+
+It is assumed that any handshaking procedures have already been completed
+(such as sending service request for git://) before this helper is started.
+
+<anything> can be any string. It is ignored. It is meant for provoding
+information to user in the URL in case that URL is displayed in some
+context.
+
+ENVIRONMENT VARIABLES
+---------------------
+GIT_TRANSLOOP_DEBUG::
+ If set, prints debugging information about various reads/writes.
+
+EXAMPLES
+--------
+git fetch fd::17 master::
+ Fetch master, using file descriptor #17 to communicate with
+ git-upload-pack.
+
+git fetch fd::17/foo master::
+ Same as above.
+
+git push fd::7,8 master (as URL)::
+ Push master, using file descriptor #7 to read data from
+ git-receive-pack and file descriptor #8 to write data to
+ same service.
+
+git push fd::7,8/bar master::
+ Same as above.

Revert the changes specified by the fourth last commit in HEAD
and create a new commit with the reverted changes.
-git revert -n master\~5..master~2::
+git revert -n master{tilde}5..master{tilde}2::
Revert the changes done by commits from the fifth last commit
in master (included) to the third last commit in master
depending on the use case, there are several ways that can be
done.
-Using "git commit -a"
-~~~~~~~~~~~~~~~~~~~~~
+Using ``git commit -a''
+~~~~~~~~~~~~~~~~~~~~~~~
If you intend that your next commit should record all modifications
of tracked files in the working tree and record all removals of
files that have been removed from the working tree with `rm`
automatically notice and record all removals. You can also have a
similar effect without committing by using `git add -u`.
-Using "git add -A"
-~~~~~~~~~~~~~~~~~~
+Using ``git add -A''
+~~~~~~~~~~~~~~~~~~~~
When accepting a new code drop for a vendor branch, you probably
want to record both the removal of paths and additions of new paths
as well as modifications of existing paths.
git ls-files -z | xargs -0 rm -f
----------------
-and then "untar" the new code in the working tree. Alternately
-you could "rsync" the changes into the working tree.
+and then untar the new code in the working tree. Alternately
+you could 'rsync' the changes into the working tree.
After that, the easiest way to record all removals, additions, and
modifications in the working tree is:
Default is the value of 'sendemail.validate'; if this is not set,
default to '--validate'.
+--force::
+ Send emails even if safety checks would prevent it.

A `gitignore` file specifies intentionally untracked files that
git should ignore.
-Note that all the `gitignore` files really concern only files
-that are not already tracked by git;
-in order to ignore uncommitted changes in already tracked files,
-please refer to the 'git update-index --assume-unchanged'
-documentation.
+Files already tracked by git are not affected; see the NOTES
+below for details.
Each line in a `gitignore` file specifies a pattern.
When deciding whether to ignore a path, git normally checks
tools, such as 'git status' and 'git add',
use patterns from the sources specified above.
-Patterns have the following format:
+PATTERN FORMAT
+--------------
- A blank line matches no files, so it can serve as a separator
for readability.
For example, "/{asterisk}.c" matches "cat-file.c" but not
"mozilla-sha1/sha1.c".
-An example:
+NOTES
+-----
+
+The purpose of gitignore files is to ensure that certain files
+not tracked by git remain untracked.
+
+To ignore uncommitted changes in a file that is already tracked,
+use 'git update-index {litdd}assume-unchanged'.
+
+To stop tracking a file that is currently tracked, use
+'git rm --cached'.
+
+EXAMPLES
+--------
--------------------------------------------------------------
$ git status
The second .gitignore prevents git from ignoring
`arch/foo/kernel/vmlinux.lds.S`.
