- 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.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.I’ll know soon enough when the Mac freezes for the first time. But I have put it into Terminal, and the command was accepted. Thankfully my Mac is not at the stage where it freezes on-cue, so technically I haven’t tested this one either. A range of ports can be specified with a dash, as it -iTCP:25-50. Order Your Mac To Automatically Reboot When It Freezes. 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.

With 11 terminal commands on macOS, you can optimize features and useful operations right on your MacBook.For information on more flags and technical explanations of each, check out lsof's man page or run man lsof at a Terminal prompt. So you need this command: defaults write AppleShowAllFiles -bool TRUE killall Finder (To change the show and hide states, you just need to change True and False together). If you want to mess around, you can use the command below to show hidden files and folders. If your switching over to Mac and will be using Terminal, it's worth the 9.99. bashprofile file for rm to run with the -i switch allowing you to get that second chance to abort from a complete removal of a file(s) from time and space. Sudo defaults write /Library/Preferences/ ScheduleFrequency X (X is the number of days you want the machine to check, for example X = 1 every day, X = 7 it takes 7 days to check). He also provides some good best practices such as modifying rm in your. Normally, macOS will automatically check for updates once a day, but if you want to change it to 2 or 3 days to check for updates, you can use the following command line to adjust:
