brc(1M)                                                   brc(1M)



     NAME
          brc, bcheckrc, rc, powerfail - system initialization shell
          scripts

     SYNOPSIS
          /etc/brc

          /etc/bcheckrc

          /etc/rc

          /etc/powerfail

     DESCRIPTION
          init executes brc, bcheckrc, and rc via entries in
          /etc/inittab when the system is changed out of SINGLE USER
          mode.  powerfail executes whenever a system power failure is
          detected.

        brc
          brc clears the mounted file system table, /etc/mtab (see
          mtab(4)), and loads any programmable micro-processors with
          their appropriate scripts.

        bcheckrc
          bcheckrc performs consistency checks to prepare the system
          for multi-user mode.  It prompts you to set the system date
          and to check the file systems with fsck(1M).

        rc
          rc starts system daemons before the terminal lines are
          enabled for multi-user mode.  In addition, it mounts file
          systems and activates accounting, error logging, system
          activity logging, and the Remote Job Entry (RJE) system.

        powerfail
          powerfail is invoked when the system detects a power
          failure.  It reloads any programmable micro-processors with
          their appropriate scripts.  It also logs that a power
          failure occurred.

     FILES
          /etc/brc

          /etc/rc
          /etc/powerfail
