ss - linux socket statistics utility output format

When using ss with -p option, user/pid/fd column jumps underneath the particular line. For instance this is it what I'm actually seeing: # ss -nulp4 State Recv-Q Send-Q Local Address:Port Peer Address:Port UNCONN 0 0 *:20000 *:* users:(("perl",pid=9316,fd=6)) UNCONN 0 0 *:10000 *:* users:(("perl",pid=9277,fd=6)) UNCONN 0 0 192.168.100.10:53 *:* users:(("named",pid=95,fd=517),("named",pid=95,fd=516)) UNCONN 0 0 127.0.0.1:53 *:* users:(("named",pid=95,fd=515),("named",pid=95,fd=514)) **Preferred output formatting**: # ss -nulp4 State Recv-Q Send-Q Local Address:Port Peer Address:Port UNCONN 0 0 *:20000 *:* users:(("perl",pid=9316,fd=6)) UNCONN 0 0 *:10000 *:* users:(("perl",pid=9277,fd=6)) UNCONN 0 0 192.168.100.10:53 *:* users:(("named",pid=95,fd=517),("named",pid=95,fd=516)) UNCONN 0 0 127.0.0.1:53 *:* users:(("named",pid=95,fd=515),("named",pid=95,fd=514)) To confirm that there are no line breaks I've tried this: # ss -nulp4 | cat -A State Recv-Q Send-Q Local Address:Port Peer Address:Port $ UNCONN 0 0 *:20000 *:* users:(("perl",pid=9316,fd=6))$ UNCONN 0 0 *:10000 *:* users:(("perl",pid=9277,fd=6))$ UNCONN 0 0 192.168.100.10:53 *:* users:(("named",pid=95,fd=517),("named",pid=95,fd=516))$ UNCONN 0 0 127.0.0.1:53 *:* users:(("named",pid=95,fd=515),("named",pid=95,fd=514))$ And indeed you can see that there were none, but now, strangely enough, output format is the way I've wanted it to be. Could someone explain what's going on here? How can I achieve my preferred formatting? This is the only thing stopping me from migrating from netstat to ss.
