![]() Our error() and die() calls may report messages with arbitrary data (e.g., filenames or even data from a remote server). Let's make it harder to cause confusion with mischievous filenames. E.g., try: git rev-parse "$(printf "\rfatal: this argument is too sneaky")" -- or git rev-parse "$(printf "\x1b[5mblinky\x1b[0m")" -- Let's block all ASCII control characters, with the exception of TAB and LF. We use both in our own messages (and we are necessarily sanitizing the complete output of snprintf here, as we do not have access to the individual varargs). And TAB and LF are unlikely to cause confusion (you could put "\nfatal: sneaky\n" in your filename, but it would at least not _cover up_ the message leading to it, unlike "\r"). We'll replace the characters with a "?", which is similar to how "ls" behaves. It might be nice to do something less lossy, like converting them to "\x" hex codes. But replacing with a single character makes it easy to do in-place and without worrying about length limitations. This feature should kick in rarely enough that the "?" marks are almost never seen. We'll leave high-bit characters as-is, as they are likely to be UTF-8 (though there may be some Unicode mischief you could cause, which may require further patches).

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 http://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 http://news.gmane.org/gmane.comp.version-control.git/, http://marc.info/?l=git and other archival sites.
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
