See a List of All Open Ports using Mac Terminal

There are a few commands that you can make use of to list all the open ports using the Mac Terminal.

Example 1: Using the `netstat` command

% netstat -an | grep LISTEN

tcp6       0      0  *.50019                *.*                    LISTEN     
tcp4       0      0  *.50019                *.*                    LISTEN     
tcp6       0      0  ::1.42050              *.*                    LISTEN     
tcp4       0      0  127.0.0.1.3306         *.*                    LISTEN     
tcp4       0      0  127.0.0.1.33060        *.*                    LISTEN     
tcp6       0      0  *.5000                 *.*                    LISTEN     
tcp4       0      0  *.5000                 *.*                    LISTEN     
tcp6       0      0  *.7000                 *.*                    LISTEN     
tcp4       0      0  *.7000                 *.*                    LISTEN

We have piped this command with grep to display only the ports that are open, which are displayed with the text LISTEN

Example 2: Using the `lsof` command

lsof stands for List Open Files, you can use this command to display all the open network connections as well.

% lsof -i -n
