git-commit-tree(1) |
|
================== |
|
|
|
NAME |
|
---- |
|
git-commit-tree - Create a new commit object |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
'git commit-tree' <tree> [-p <parent commit>]\* < changelog |
|
|
|
DESCRIPTION |
|
----------- |
|
This is usually not what an end user wants to run directly. See |
|
linkgit:git-commit[1] instead. |
|
|
|
Creates a new commit object based on the provided tree object and |
|
emits the new commit object id on stdout. |
|
|
|
A commit object may have any number of parents. With exactly one |
|
parent, it is an ordinary commit. Having more than one parent makes |
|
the commit a merge between several lines of history. Initial (root) |
|
commits have no parents. |
|
|
|
While a tree represents a particular directory state of a working |
|
directory, a commit represents that state in "time", and explains how |
|
to get there. |
|
|
|
Normally a commit would identify a new "HEAD" state, and while git |
|
doesn't care where you save the note about that state, in practice we |
|
tend to just write the result to the file that is pointed at by |
|
`.git/HEAD`, so that we can always see what the last committed |
|
state was. |
|
|
|
OPTIONS |
|
------- |
|
<tree>:: |
|
An existing tree object |
|
|
|
-p <parent commit>:: |
|
Each '-p' indicates the id of a parent commit object. |
|
|
|
|
|
Commit Information |
|
------------------ |
|
|
|
A commit encapsulates: |
|
|
|
- all parent object ids |
|
- author name, email and date |
|
- committer name and email and the commit time. |
|
|
|
While parent object ids are provided on the command line, author and |
|
committer information is taken from the following environment variables, |
|
if set: |
|
|
|
GIT_AUTHOR_NAME |
|
GIT_AUTHOR_EMAIL |
|
GIT_AUTHOR_DATE |
|
GIT_COMMITTER_NAME |
|
GIT_COMMITTER_EMAIL |
|
GIT_COMMITTER_DATE |
|
EMAIL |
|
|
|
(nb "<", ">" and "\n"s are stripped) |
|
|
|
In case (some of) these environment variables are not set, the information |
|
is taken from the configuration items user.name and user.email, or, if not |
|
present, system user name and fully qualified hostname. |
|
|
|
A commit comment is read from stdin. If a changelog |
|
entry is not provided via "<" redirection, 'git-commit-tree' will just wait |
|
for one to be entered and terminated with ^D. |

The passwd(5) gecos field couldn't be read |
|
Your parents must have hated you!:: |
|
The passwd(5) gecos field is longer than a giant static buffer. |

The passwd(5) name field is longer than a giant static buffer. |
