     HISTORY(1)                                             HISTORY(1)

     NAME
          history - print file names from the dump

     SYNOPSIS
          history [ -Dabcemnw ] [ -fu ] [ -d dumpfilesystem ] [ -s
          yyyymmdd ] files ...

     DESCRIPTION
          History prints the names, dates, and sizes, and modifier 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 example,

               history /adm/users

          produces

               May 14 15:29:18 EDT 2001 /adm/users 10083 [adm]
               May 14 15:29:18 EDT 2001 /n/dump/2001/0515/adm/users 10083 [adm]
               May 11 17:26:24 EDT 2001 /n/dump/2001/0514/adm/users 10481 [adm]
               May 10 16:40:51 EDT 2001 /n/dump/2001/0511/adm/users 10476 [adm]
                    ...

          The -D option causes diff(1) to be run for each adjacent
          pair of dump files.  The options -abcemnw are passed through
          to diff; the little-used diff option -f is replaced by the
          functionality described below, and the -r option is disal-
          lowed.

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

          The -d option selects some other dump file system such as
          /n/bootesdump.

          The -f option is accepted but ignored by compatibility with
          other history implementations.

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

     EXAMPLES

               history /usr/ches/tmp
