X11-unix/* find out all processes that connect to X server ss-s list current socket details: Explanation: netstat is traversing each PID directory under/proc, ss directly reads the statistics under/proc/net. Therefore, the resource consumption and time consumed by ss execution are much less than that of netstat.
