Trouble with cut command after executing ss command

Here is the basic cut syntax I'm using:

[jay@webserver ~]$ ss -tn
State      Recv-Q Send-Q                                  Local Address:Port                                                 Peer Address:Port              
ESTAB      0      52                                      xxx.xx.xx.xx:xx                                                  xxx.xx.xx.xx:xx              
ESTAB      0      232                                     xxx.xx.xx.xx:xx                                                 xxx.xx.xx.xx:xx

But when I try to cut on the fields, I don't get the appropriate output:

[jay@webserver ~]$ ss -tn | grep -v State | cut -d$'\t' -f3,4
ESTAB      0      36     xxx.xx.xx.xx:xx                 xxx.xx.xx.xx:xx              
ESTAB      0      68     xxx.xx.xx.xx:xx                 xxx.xx.xx.xx:xx

The only thing I can think of is that the delimter isn't a tab but in that case how could I get the output I'm wanting?

Solution

  • ss's output is separated by spaces. I suggest to use awk:

    ss -tn | grep -v State | awk '{print $3,$4}'
