The idea of `--exec` is to append an `exec` call after each `pick`. Since the introduction of fixup!/squash! commits, this idea was extended to apply to "pick, possibly followed by a fixup/squash chain", i.e. an exec would not be inserted between a `pick` and any of its corresponding `fixup` or `squash` lines. The current implementation uses a dirty trick to achieve that: it assumes that there are only pick/fixup/squash commands, and then *inserts* the `exec` lines before any `pick` but the first, and appends a final one. With the todo lists generated by `git rebase --rebase-merges`, this simple implementation shows its problems: it produces the exact wrong thing when there are `label`, `reset` and `merge` commands. Let's change the implementation to do exactly what we want: look for `pick` lines, skip any fixup/squash chains, and then insert the `exec` line. Lather, rinse, repeat. Note: we take pains to insert *before* comment lines whenever possible, as empty commits are represented by commented-out pick lines (and we want to insert a preceding pick's exec line *before* such a line, not afterward). While at it, also add `exec` lines after `merge` commands, because they are similar in spirit to `pick` commands: they add new commits.

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-.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://public-inbox.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
