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:
The maximum information the command will provide is:
path-name i-number size uid
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 .
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.
