DUMPFS(8)

NAME

     dumpfs -- dump file system information

SYNOPSIS

     dumpfs [-m] [filesys | device]

DESCRIPTION

     The dumpfs utility prints out the super block and cylinder group informa-
     tion for the file system or special device specified, unless -m is speci-
     fied.  The listing is very long and detailed.  This command is useful
     mostly for finding out certain file system information such as the file
     system block size and minimum free space percentage.

     If -m is specified, the file system is marshalled in terms of a newfs(8)
     command to generate the file system.
