DMESG(C)                 XENIX System V                  DMESG(C)



     Name
          dmesg - Displays the system messages on the console.

     Syntax
          dmesg [ - ]

     Description
          The dmesg command displays all the system messages that have
          been generated since the last time the system was booted.
          If the option - is specified, it displays only those
          messages that have been generated since the last time the
          dmesg command was performed.

          dmesg can be invoked periodically by placing instructions in
          the file /usr/lib/crontab . It can also be invoked
          automatically by /etc/rc whenever the system is booted.  See
          ``Notes'', below.

          dmesg logs all error messages it prints in
          /usr/adm/messages.  If dmesg is invoked automatically, the
          messages file continues to grow and can become very large.
          The system administrator should occasionally erase its
          contents.

     Files
          /etc/dmesg
          /usr/adm/messages
          /usr/adm/msgbuf

     Notes
          dmesg is included in this release for backwards
          compatibility only.  The device /dev/error provides a more
          flexible means of logging error messages, and is recommended
          over dmesg.  See error(M) for more information.
