      true, false - return exit status zero or one respectively

 SYNOPSIS    [Toc]    [Back]
      true

      false

 DESCRIPTION    [Toc]    [Back]
      The command true does nothing, and returns exit code zero.  The
      command false does nothing, and returns exit code one.  They are
      typically used to construct command procedures.

 RETURN VALUE    [Toc]    [Back]
      Exit values are:

            0      always from true.
            1      always from false.

 EXAMPLES    [Toc]    [Back]
      This command loop repeats without end:

           while true
               do
                    command
               done

 WARNINGS    [Toc]    [Back]
      true is typically used in shell scripts.  Some shells provide a
      built-in version of true (and false) that is more efficient than the
      standalone versions.
