- u user only returns commands owned by the named user.When used with -P above, it can significantly speed up lsof's output. -n disables the conversion of network numbers to hostnames.-P disables the conversion of port numbers to port names, speeding up output.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.Retrieving DNS details from Terminal in new versions of OS X including in OS X Yosemite, Mac OS X 10.7 Lion, OS X 10.8 Mountain Lion, 10. The precursor can also be used to specify hostnames in the same way, but both remote IP addresses and hostnames cannot be used simultaneously. This is done from the command line, so launch the Terminal app and type one of the following command strings, dependent on the version of OS X that is running on the Mac. 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. I just want to know my current IP, subnet mask, default gateway and DNS. iTCP:25 returns only TCP connections on port 25. Is there a command for the OS X Terminal that shows you only the most vital IP configuration information about your machine I know there is 'ifconfig' but that brings up a bunch of (in most cases) unnecessary information. 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. If the output doesn’t look up to date, or if it’s missing an IP you believe should be there, ping the broadcast IP (typically the last result of arp -a ending with. Adding a 4, as in -i4, displays only IPv4 connections.
