ff - list file names and statistics for a file system
ff [-F FSType] [-V] [generic_options] [-o specific_options] special...
ff prints the pathnames and inode numbers of files in the
file system which resides on the special device special. Other
information about the files may be printed using options described below.
Selection criteria may be used to instruct ff to only print
information for certain files. If no selection criteria are specified,
information for all files considered will be printed (the default); the
-i option may be used to limit files to those whose inodes are
specified.
Output is sorted in ascending inode number order. The default line
produced by ff is:
path-name i-number
The maximum information the command will provide is:
path-name i-number size uid
-F
Specify the FSType on which to operate. The
FSType should either be specified here or be determinable from
/etc/vfstab by matching the special with an entry in the table,
or by consulting /etc/default/fs.
-V
Echo the complete command line, but do not execute the
command. The command line is generated by using the options and arguments
provided by the user and adding to them information derived from
/etc/vfstab. This option may be used to verify and validate the command
line.
generic_options
Options that are supported by most FSType-specific
modules of the command. The following options are available:
-I
Do not print the i-node number after each path
name.
-l
Generate a supplementary list of all path names for
multiply-linked files.
-p prefix
The specified prefix will be added to each
generated path name. The default is `.' (dot).
-s
Print the file size, in bytes, after each path
name.
-u
Print the owner's login name after each path name.
-a -n
Select if the file has been accessed in n
days.
-m -n
Select if the file has been written or created in
n days.
-c -n
Select if file's status has been changed in n
days.
-n file
Select if the file has been modified more recently than
the argument file.
-i i-node-list
Generate names for only those i-nodes specified in
i-node-list. i-node-list is a list of numbers separated by
commas (with no intervening spaces).
-o
Specify FSType-specific options in a comma
separated (without spaces) list of suboptions and keyword-attribute pairs for
interpretation by the FSType-specific module of the command.
special
A special device.
See largefile(7) for the description of the behavior of
ff when encountering files greater than or equal to 2 Gbyte ( 2^31
bytes).
/etc/default/fs
default local file system type. Default values can be set
for the following flags in
/etc/default/fs. For example:
LOCAL=ufs
LOCAL
The default partition for a command if no FSType is
specified.
/etc/vfstab
list of default parameters for each file system
This command may not be supported for all FSTypes.
The -a, -m, and -c flags examine the
st_atime, st_mtime, and st_ctime fields of the
stat structure respectively. (See stat(2).)
