I do not recommend that you use a pre-compiled lsof binary. It is better that you compile lsof for yourself from the distributed sources. Binaries are contained in subdirectories with names matching the SCO OpenServer releases on which they were produced. All binaries have been compiled with the HASSECURITY option disabled -- i.e., once they or the user has permission to read /dev/kmem, they may be used to look at all open files.
