   6git-commit-tree - Create a new commit object

   9SYNOPSIS
  10--------
  11'git-commit-tree' <tree> [-p <parent commit>]\* < changelog
  12
  13DESCRIPTION
  14-----------
  15This is usually not what an end user wants to run directly.  See
  16gitlink:git-commit[1] instead.
  17
  18Creates a new commit object based on the provided tree object and
  19emits the new commit object id on stdout. If no parent is given then
  20it is considered to be an initial tree.
  21
  22A commit object usually has 1 parent (a commit after a change) or up
  23to 16 parents.  More than one parent represents a merge of branches
  24that led to them.
  25
  26While a tree represents a particular directory state of a working
  27directory, a commit represents that state in "time", and explains how
  28to get there.
  29
  30Normally a commit would identify a new "HEAD" state, and while git
  31doesn't care where you save the note about that state, in practice we
  32tend to just write the result to the file that is pointed at by
  33`.git/HEAD`, so that we can always see what the last committed
  34state was.
  35
  36OPTIONS
  37-------
  38<tree>::
  39        An existing tree object
  40
  41-p <parent commit>::
  42        Each '-p' indicates the id of a parent commit object.
  43

  45Commit Information
  46------------------
  47
  48A commit encapsulates:
  49
  50- all parent object ids
  51- author name, email and date
  52- committer name and email and the commit time.
  53
  54If not provided, "git-commit-tree" uses your name, hostname and domain to
  55provide author and committer info. This can be overridden by
  56either `.git/config` file, or using the following environment variables.
  57
  58        GIT_AUTHOR_NAME
  59        GIT_AUTHOR_EMAIL
  60        GIT_AUTHOR_DATE
  61        GIT_COMMITTER_NAME
  62        GIT_COMMITTER_EMAIL
  63
  64(nb "<", ">" and "\n"s are stripped)
  65
  66In `.git/config` file, the following items are used for GIT_AUTHOR_NAME and
  67GIT_AUTHOR_EMAIL:
  68
  69        [user]
  70                name = "Your Name"
  71                email = "your@email.address.xz"
  72
  73A commit comment is read from stdin (max 999 chars). If a changelog
  74entry is not provided via "<" redirection, "git-commit-tree" will just wait
  75for one to be entered and terminated with ^D.

  80You don't exist. Go away!::
  81    The passwd(5) gecos field couldn't be read
  82Your parents must have hated you!::
  83    The password(5) gecos field is longer than a giant static buffer.
  84Your sysadmin must hate you!::
  85    The password(5) name field is longer than a giant static buffer.
