The Linux command ss most commonly stands for “socket statistics.”

Quick Scoop

  • ss is a modern tool used to display detailed information about network sockets on a Linux system, similar to (but faster than) netstat.
  • Many references and guides explicitly expand it as “socket statistics,” since its primary job is to dump statistics and details about sockets.
  • You use it to inspect things like:
    • Open TCP/UDP connections
    • Listening ports
    • Socket states (ESTAB, LISTEN, etc.)
    • Per-socket details for troubleshooting network issues

Tiny example

  • Running ss with no arguments lists active non-listening connections.
  • Running ss -s gives a nice high-level summary of socket statistics.

So if someone asks, “What phrase does the Linux command ss stand for?”, the accepted and widely-used expansion is “socket statistics.”
