NAME

ff − list file names and statistics for a file system

SYNOPSIS

/etc/ff [options] special

DESCRIPTION

Ff reads the i-list and directories of the special file, assuming it to be a file system, saving i-node data for files which match the selection criteria.  Output consists of the path name for each saved i-node, plus any other file information requested using the print options below.  Output fields are positional.  The output is produced in i-node order; fields are separated by tabs.  The default line produced by ff is:

path-name i-number

With all options enabled, output fields would be:

path-name i-number size uid

The argument n in the option descriptions that follow is used as a decimal integer (optionally signed), where +n means more than n, −n means less than n, and n means exactly n. A day is defined as a 24 hour period.

−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 .. 

−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 i-node has been accessed in n days. 

−m n Select if the i-node has been modified in n days. 

−c n Select if the i-node has been changed in n days. 

−n file Select if the i-node 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.

EXAMPLE

ff −I /dev/diskroot

generates a list of the names of all files on a specified file system. 

ff −m −1 /dev/diskusr > /log/incbackup/usr/tuesday

produces an index of files and i-numbers which are on a file system and have been modified in the last 24 hours. 

ff −i 451,76 /dev/rrp7

obtains the path names for i-nodes 451 and 76 on a specified file system. 

SEE ALSO

finc(1M), find(1), frec(1M), ncheck(1M). 

BUGS

Only a single path name out of any possible ones will be generated for a multiply linked i-node, unless the −l option is specified.  When −l is specified, no selection criteria apply to the names generated.  All possible names for every linked file on the file system will be included in the output. 

On very large file systems, memory may run out before ff does.
