Two commands will tell you has a file open - "fuser" and "ofiles".  "fuser"
is standard with System V.  "ofiles" I believe is mostly a SunOS command,
I'm sure someone from that universe can fill you in.

You might also want to look into the "crash" command, particularly the
"user" subcommand.  It will tell you about open files per process.  You
can then determine the files each process has open by going from the
open file descriptor information to the file table to the inode table.
