ss:tldr:0d58e
The ss
command in Linux is used to display detailed information about network connections, network interfaces, and socket statistics. It is a powerful replacement of the older netstat
command.
In the given command, ss -a ${select}
, the -a
option is used to display all sockets, including listening, connected, and idle sockets. The ${select}
refers to a variable or parameter that should be substituted with an actual value when running the command.
The command can be modified by replacing ${select}
with specific parameters to filter and display specific information about sockets or connections. For example, using ${select}
as an IP address would display only connections and sockets associated with that IP address.
Overall, the command ss -a ${select}
lists all sockets and their corresponding details, allowing for specific filters and parameters to manipulate the displayed information.
