Process IDs can also be excluded with a ^, as in 123,^456, which would specifically exclude PID 456. Multiple PIDs can be set by using commons, such as -p 123,456,789. -p restricts lsof to a particular process ID (PID).Instead, it allows the user to specify the protocol and status for the command to return. But when paired with the -i flag, -s works differently. -s typically forces lsof to display file size.The precursor can also be used to specify hostnames in the same way, but both remote IP addresses and hostnames cannot be used simultaneously. IPv6 addresses can be specified in the same fashion. Using returns only connections to the IPv4 address 1.2.3.4.A range of ports can be specified with a dash, as it -iTCP:25-50.
iTCP:25 returns only TCP connections on port 25. iTCP or -iUDP returns only TCP and UDP connections. The -i flag also can be expanded to specify further details.Adding a 6 instead ( -i6) displays only IPv6 connections. Adding a 4, as in -i4, displays only IPv4 connections. -i displays open network connections and the name of the process that is using the connection.
