NAME
     bkhistory - report on completed backup operations

SYNOPSIS
     bkhistory [-hl] [-f field_separator] [-d dates]  [-o  names]
     [-t tags]
     bkhistory -p period

DESCRIPTION
     bkhistory without options reports a summary of the  contents
     of  the  backup  history log, bkhist.tab.  Backup operations
     are sorted alphabetically by tag.  For each tag,  operations
     are  listed  from  most to least recent.  backup(1M) updates
     this log after each successful backup operation.

     bkhistory may be executed only by a user with the  superuser
     privilege.

     bkhistory -p assigns a rotation period (in  weeks)  for  the
     history  log; all entries older than the specified number of
     weeks are deleted from the log.  The default rotation period
     is one (1) week.

  Options
     -d dates
          Restricts the report to backup operations performed  on
          the  specified  dates.   dates  are in the date format.
          day, hour, minute, and  year, are optional and will  be
          ignored.   The  list of dates is either comma-separated
          or blank-separated and surrounded by quotes.

     -f field_separator
          Suppresses field wrap on the display and  specifies  an
          output  field  separator to be used.  The value of c is
          the character that will appear as the  field  separator
          on  the  display output.  For clarity of output, do not
          use a separator character that is likely to occur in  a
          field.   For  example,  do not use the colon as a field
          separator character if the display will  contain  dates
          that  use  a  colon to separate hours from minutes.  To
          use the default field separator (tab), specify the null
          character ("") for c.

     -h   Suppresses header for the reports.

     -l   Displays a long form of the report.  This  produces  an
          ls  -l  listing  of  the  files  included in the backup
          archive (if backup tables  of  contents  are  available
          on-line).

     -o names
          Restricts  the  report  to  the  specified  originating

          objects  (file systems or data partitions).  names is a
          list of onames and/or odevices.  [See bkreg(1M)].

          The list of names is either comma-separated  or  blank-
          separated and surrounded by quotes.

     -p period
          Sets the number of weeks of information  that  will  be
          saved  in  the backup history table.  The minimum value
          of period is 1, which is also the default  value.   the
          size of int.  By default, period is 1.

     -t tags
          Restricts the report  to  backups  with  the  specified
          tags.  tags is a list of tag values as specified in the
          backup register.  The list of  tags  is  either  comma-
          separated or blank-separated and surrounded by quotes.

DIAGNOSTICS
     The exit codes for the bkhistory command are the following:

          0 =  the task completed successfully
          1 =  one or more parameters to bkhistory are invalid
          2 =  an error has occurred, causing bkhistory  to  fail
               to complete all portions of its task

EXAMPLES
     Example 1:
          bkhistory -p 3
     sets the rotation period for the history log to three weeks.
     Entries  older  than  three  weeks are deleted from the log.
     Example 2:
          bkhistory -t SpoolDai,UsrDaily,TPubsWed
     displays a report of completed  backup  operations  for  the
     three tags listed.  Example 3:
          bkhistory -l -o /usr
     Displays an ls -l listing of the files that were  backed  up
     from  /usr  (the  originating object) if there is a table of
     contents.

                    tion   about  successfully  completed  backup
