The command "ss -lt src :${8080}" is used to display active internet connections associated with a specific source port number, in this case, port number 8080.
Here's the breakdown of the command:
-
"ss" is a command that stands for "socket statistics". It is used to display information about active network connections on a Linux system.
-
"-lt" are the options to filter and format the output of the ss command. "-l" shows only listening sockets (open ports) and "-t" shows only TCP connections.
-
"src" is a filter to specify the source address or port number of the connections to display.
-
":${8080}" is the specific source port number to filter the connections. "${8080}" is a variable that represents the value of port number 8080.
Overall, the command is used to show active TCP connections and listening sockets with a source port number of 8080.
