Name
       opser - interactive program for system maintenance

Syntax
       opser

Description
       The  program is a utility that simplifies normal system and incremental
       backup.	It is invoked by default when the system operator logs	in  to
       the  operator  account.	The system then runs the utility in place of a
       shell.  The utility prompts the operator to bring the system to single-
       user mode for file maintenance. This includes a file system consistency
       check and file system backup, and then  prompts	to  restart  multiuser
       mode.

       Network	allows the operator to perform commands on a slave system. The
       master system name must be in the file on  the  slave  system  and  the
       slave name in the in the master system's file.  If necessary, the oper‐
       ator can escape to the shell, execute  commands,	 and  return.	Online
       help  is	 provided.  The program allows remote file system backup, file
       system check, restart and both local and remote	shell  command	execu‐
       tion.

Restrictions
       ·   The local utility supports only tape as a backup media.

       ·   The remote utility allows backup to files, disks, or tapes.

       ·   The utility must be run from the system console; if run from a ter‐
	   minal, its operation is limited.

       ·   The utility does not contain file restore capability.

       ·   The operator must escape to the shell to perform this function.

Diagnostics
       Included in the utility as it runs.
