lsof -i how to understand the output message?

fantasy1215 · 06-03-2012, 11:22 PM

I use lsof -i to list all the opened socket file descriptor.And I use this command to list all the listened port, But I have some doubt about the output messages.
Like:

Code:

mycmd  8983 userw    5u  IPv4     39189       TCP *:bmc-grx (LISTEN)

This line give the port name bmc-grx instead of port number.
How could I know the listened port number instead of the port mapped name?
Thanks in advance!

Use "-n". To avoid resolving about anything I use "-Pwln", see 'man lsof' for the meaning of those switches.
