The 'test_pause' function, which is designed to help interactive debugging and exploration of tests, currently inherits the value of HOME and TERM set by 'test-lib.sh': HOME="$TRASH_DIRECTORY" and TERM=dumb. It also invokes the shell defined by TEST_SHELL_PATH, which defaults to /bin/sh (through SHELL_PATH). Changing the value of HOME means that any customization configured in a developers' shell startup files and any Git aliases defined in their global Git configuration file are not available in the shell invoked by 'test_pause'. Changing the value of TERM to 'dumb' means that colored output is disabled for all commands in that shell. Using /bin/sh as the shell invoked by 'test_pause' is not ideal since some platforms (i.e. Debian and derivatives) use Dash as /bin/sh, and this shell is usually compiled without readline support, which makes for a poor interactive command line experience. To make the interactive command line experience in the shell invoked by 'test_pause' more pleasant, save the values of HOME and TERM in USER_HOME and USER_TERM before changing them in test-lib.sh, and add options to 'test_pause' to optionally use these variables to invoke the shell. Also add an option to invoke SHELL instead of TEST_SHELL_PATH, so that developer's interactive shell is used. We use options instead of changing the behaviour unconditionally since these three variables can slightly change command behaviour. Moreover, using the original HOME means commands could overwrite files in a user's home directory. Be explicit about these caveats in the new 'Usage' section in test-lib-functions.sh. Finally, add '[options]' to the test_pause synopsys in t/README, and mention that the full list of helper functions and their options can be found in test-lib-functions.sh.

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
