udetect - Find subset files that have changed since installation
-m Reports missing files by printing inventory records that specify files
that do not exist on the disk.
-s Specifies strict reporting. Prints a record if any of the attributes
in the record do not match the current state of the file on the disk.
-? Displays a usage message.
The udetect command reads setld inventory records from standard input. For
each record, the file in the path field is checksummed and checked with the
lstat(2) system call. Records for which there are discrepancies in the
checksum or size are written to standard output.
