Eric Sunshine d73f5cfa89 chainlint.sed: stop splitting "(..." into separate lines "(" and "..." Because `sed` is line-oriented, for ease of implementation, when chainlint.sed encounters an opening subshell in which the first command is cuddled with the "(", it splits the line into two lines: one containing only "(", and the other containing whatever follows "(". This allows chainlint.sed to get by with a single set of regular expressions for matching shell statements rather than having to duplicate each expression (one set for matching non-cuddled statements, and one set for matching cuddled statements). However, although syntactically and semantically immaterial, this transformation has no value to test authors and might even confuse them into thinking that the linter is misbehaving by inserting (whitespace) line-noise into the shell code it is validating. Moreover, it also allows an implementation detail of chainlint.sed to seep into the chainlint self-test "expect" files, which potentially makes it difficult to reuse the self-tests should a more capable chainlint ever be developed. To address these concerns, stop splitting cuddled "(..." into two lines. Note that, as an implementation artifact, due to sed's line-oriented nature, this change inserts a blank line at output time just before the "(..." line is emitted. It would be possible to suppress this blank line but doing so would add a fair bit of complexity to chainlint.sed. Therefore, rather than suppressing the extra blank line, the Makefile's `check-chainlint` target which runs the chainlint self-tests is instead modified to ignore blank lines when comparing chainlint output against the self-test "expect" output. This is a reasonable compromise for two reasons. First, the purpose of the chainlint self-tests is to verify that the ?!AMP?! annotations are being correctly added; precise whitespace is immaterial. Second, by necessity, chainlint.sed itself already throws away all blank lines within subshells since, when checking for a broken &&-chain, it needs to check the final _statement_ in a subshell, not the final _line_ (which might be blank), thus it has never made any attempt to precisely reproduce blank lines in its output.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.

Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
