true(1)

     NAME
          true - do nothing, successfully

     SYNOPSIS
          true
          true {--help,--version}

     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          This manual page documents the GNU version of true (and
          probably every other version, as well).  true does nothing
          except return an exit status of 0, meaning ``success''.  It
          can be used as a place holder in shell scripts where a
          successful command is needed, although the shell built-in
          command `:' (colon) does the same thing faster.

        OPTIONS
          When GNU true is invoked with exactly one argument, the
          following options are recognized:

          --help
               Print a usage message on standard output and exit
               successfully.

          --version
               Print version information on standard output then exit
               successfully.
