      intro - introduction to general commands (tools and utilities)


      Section one of the manual contains most of the commands which comprise
      the BSD user environment.  Some of the commands included in section one
      are text editors, command shell interpreters, searching and sorting
      tools, file manipulation commands, system status commands, remote file
      copy commands, mail commands, compilers and compiler tools, formatted
      output tools, and line printer commands.
      All commands set a status value upon exit which may be tested to see if
      the command completed normally.  Traditionally, the value 0 signifies
      successful completion of the command, while a value >0 indicates an
      error.  Some commands attempt to describe the nature of the failure by
      using exit codes as defined in sysexits(3), while others simply set the
      status to an arbitrary value >0 (typically 1).
