, as follows: # lsof |grep/var/log/messagessyslogd 1283 root 2w REG 3,3 5381017 1773647/var/log/messages (deleted)from the above information you can see that the PID 1283 (syslogd) Open file has a file descriptor of 2. You can also see that/var/log/messages has been flagged for deletion. So we can view the corresponding information in/PROC/1283/FD/2 (each file descriptor for the process corresponding to a digitally named file under FD), as follows:# h
