一般の arch コマンド

arch の全てのコマンドは tla プログラム経由で利用し, ふつうのサブコマンドの文法を使います:

        % tla <sub-command> <options> <parameters>

サブコマンドの一覧を得るには:

        % tla help

コマンドのオプションの概要を得るには:

        % tla <sub-command> -h

より詳細なヘルプ情報を得るには:

        % tla <sub-command> -H

例えば, 以下を試してください:

        % tla my-id -H
        print or change your id
        usage: tla my-id [options] [id]
        
          -h, --help     Display a help message and exit.
          -H             Display a verbose help message and exit.
          -V, --version  Display a release identifier string
                         and exit.
          -e, --errname  specify program name for errors
          -u, --uid      print only the UID portion of the ID
        
        With no argument print your arch id.
        
        With an argument, record ID-STRING as your id
        in ~/.arch-params/=id
        
        Your id is recorded in various archives and log messages
        as you use arch.  It must consist entirely of printable
        characters and fit on one line.  By convention, it should
        have the form of an email address, as in this example:
        
                Jane Hacker <jane.hacker@gnu.org>
        
        The portion of an id string between < and > is called your
        uid.  arch sometimes uses your uid as a fragment when generating
        unique file names.
        
        The option -u (--uid) causes only the uid part of your id string
        to be printed.

コマンド間での, オプション名とパラメータの文法は大変規則的です. 様々なコマンドを学習するにつれて見につくことでしょう.
