Johannes Sixt 191eb491ed generate-cmdlist.sh: spawn fewer processes 
The function get_categories() is invoked in a loop over all commands.
As it runs several processes, this takes an awful lot of time on
Windows. To reduce the number of processes, move the process that
filters empty lines to the other invoker of the function, where it is
needed. The invocation of get_categories() in the loop does not need
the empty line filtered away because the result is word-split by the
shell, which eliminates the empty line automatically.

Furthermore, use sort -u instead of sort | uniq to remove yet another
process.

[Ævar: on Linux this seems to speed things up a bit, although with
hyperfine(1) the results are fuzzy enough to land within the
confidence interval]:

$ git show HEAD~:generate-cmdlist.sh >generate-cmdlist.sh.old
$ hyperfine --warmup 1 -L s ,.old -p 'make clean' 'sh generate-cmdlist.sh{s} command-list.txt'
Benchmark #1: sh generate-cmdlist.sh command-list.txt
  Time (mean ± σ):     371.3 ms ±  64.2 ms    [User: 430.4 ms, System: 72.5 ms]
  Range (min … max):   320.5 ms … 517.7 ms    10 runs

Benchmark #2: sh generate-cmdlist.sh.old command-list.txt
  Time (mean ± σ):     489.9 ms ± 185.4 ms    [User: 724.7 ms, System: 141.3 ms]
  Range (min … max):   346.0 ms … 885.3 ms    10 runs

Summary
  'sh generate-cmdlist.sh command-list.txt' ran
    1.32 ± 0.55 times faster than 'sh generate-cmdlist.sh.old command-list.txt'

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
