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 operator 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.

o The utility must be run from the system console; if run from a terminal, its operation is limited.
