Alex, I did something simple; on one window did more/etc/mail/sendmail.cf on another window did lsof -o -b -p XXX -w where XXX is hte process number and the SIZE column does not change to OFFSET! the size reflects the size of sendmail.cf - I was hoping the "-o" would change the SIZE column to OFFSET column and show at what offset the program has read into the file? AM I doing something wrong? THanks so much.
