ff — list file names and statistics for a file system


/usr/sbin/ff [-F FStype] [-o specific_options] [-V] special ...


The ff command reads the i-list and directories of each special file, assuming it to be a file system, saving i-node data for files that match the selection criteria. Output consists of the path name for each saved i-node, plus any other file information requested with the -o option. Output fields are positional. The output is produced in i-node order; fields are separated by tabs. The default line produced by ff includes the path name and i-number fields.

Options and Arguments

ff recognizes the following options and arguments:

-F FStype

Specify the file system type on which to operate (see fstyp(1M) and fs_wrapper(5)). If this option is not included on the command line, then the file system type is determined from the file /etc/fstab by matching each special with an entry in that file. If there is no entry in /etc/fstab, then the file system type is determined from the file /etc/default/fs.

-o specific_options

Specify options specific to each file system type. specific_options is a list of suboptions and/or keyword/attribute pairs intended for a specific FStype-specific module of the command. See the file-system-specific man pages for a description of the specific_options supported, if any.


Echo the completed command line, but perform no other action. The command line is generated by incorporating the user-specified options and other information derived from /etc/fstab. This option allows the user to verify the command line.


List the path names and i-numbers of all files in the file system /dev/dsk/c1d2s0:

ff /dev/dsk/c1d2s0

Execute the ff command on HFS file system /dev/dsk/c1d2s0:

ff -F hfs /dev/dsk/c1d2s0

Display a completed command line without executing the command:

ff -V /dev/dsk/c1d2s0
