     NAME
          hist, history - print file names from the dump

     SYNOPSIS
          hist [ -vdu ] [ -s yyyymmdd ] files ...

     DESCRIPTION
          Hist prints the names, dates, and sizes of all versions of
          the named files, looking backwards in time, stored in the
          dump file system.  If the file exists in the main tree, the
          first line of output will be its current state.  For exam-
          ple,

               hist ~rsc/.bash_history

          produces

          The -v option enables verbose debugging printout.

          The -d option causes diff(1) -c to be run for each adjacent
          pair of dump files, while -b runs diff -cb.

          The -u option causes times to be printed in GMT (UT) rather
          than local time.

          Finally, the -s option sets the starting (most recent) date
          for the output.
