interact with backup operations to service media insertion prompts

From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

bkoper - interact with backup operations to service media insertion prompts

SYNOPSIS

bkoper [-u users]

DESCRIPTION

Backup operations may require an operator to insert media and to confirm proper volume labels. The bkoper command provides a mailx-like interface for these operator interactions. It begins by printing a list of headers. Each header describes a backup operation requiring interaction, the device requiring attention including the media type and label of the volume to be inserted (see EXAMPLE). The system displays prompts and the operator issues commands to resolve the backup operation. Typing a carriage return invokes the current header. If no headers have been serviced, the current header is the first header on the list. If a header has been selected and serviced, the current header is the next one following. bkoper may be executed only by a user with superuser privilege. By default, the operator may interact only with backup operations that were started by the same user ID . If the -u users option is given, the operator interacts only with backup operations started by the specified user(s).

Commands

!shell-command
          Escapes to the shell.  The remainder of  the  line
          after  the ! is sent to the UNIX system shell (sh)
          to be interpreted as a command.

=         Prints the current backup operation number.

?         Prints this summary of commands.

[p|t] [n] Both the p and t options operate in the same  way.
          Either option will interact with the backup opera-
          tion described by the n'th header.  n defaults  to
          the current header number.

h         Prints the list of backup operations.

q         Quits from bkoper.

DIAGNOSTICS

The exit codes for bkoper are the following:

0 = successful completion of the task
1 = one or more parameters to bkoper are invalid.
2 = an error has occurred which caused bkoper to fail to

complete all portions of its task.

EXAMPLE

     A sample header is shown  below.   Items  appearing  in  the
     header  are  listed  in the following order:  header number,
     job-ID, tag, originating device, destination group, destina-
     tion  device, destination volume labels.  [See bkreg(1M) for
     descriptions of items.]  Not every  header  contains  values
     for  all  these fields; if a destination group is not speci-
     fied in /etc/bkup/bkreg.tab, then no value for ``destination
     group'' appears in the header.

       2 back-112 fs2daily /dev/dsk/c1d0s8 ctape /dev/ctape/c4d0s2 -
Backup headers are numbered on the basis of arrival;  the  oldest
header has the lowest number.  If the destination device does not
have a volume label, a dash is displayed in the header.
