The command "ss -pt dst :${ssh}" is used to display active network connections on a Linux system based on a given criteria.
- "ss" is a command-line utility used for monitoring network connections and sockets on a Linux system.
- "-pt" are options or flags passed to the "ss" command. This combination of options specifies that the output should include TCP connections (-t) and their associated processes (-p).
- "dst" is a filter that specifies that only connections that are outgoing (i.e., destination connections) should be displayed.
- ":${ssh}" is a variable placeholder that is used to substitute the value of the "ssh" environment variable when the command is executed. The value of the "ssh" variable is expected to be the port number of the SSH service (usually 22).
In summary, the "ss -pt dst :${ssh}" command is used to show all active TCP connections that are outgoing to the port specified by the "ssh" environment variable.
