ss:tldr:3e084

The command "ss -4t src ${192-168-16}" can be broken down as follows:

• "ss" is the name of the command being executed. It stands for "socket statistics" and is used for displaying network socket-related information.
• "-4t" are options or flags passed to the ss command. In this case, "-4" specifies that IPv4 sockets should be displayed, and "-t" specifies that only TCP sockets should be shown (excluding UDP, RAW, and UNIX sockets).
• "src" specifies the filter criteria for displaying sockets based on their source address.
• "${192-168-16}" is a variable that contains the source address filter value. However, it seems to be written incorrectly with a dash instead of periods. It might be intended to represent an IP address range or network subnet.

Overall, this command aims to show IPv4 TCP sockets where the source address matches a specific criteria specified by the variable "${192-168-16}". However, the actual value of "${192-168-16}" is not clear due to the incorrect formatting.
