my host red hat enterprise linux server release 5.4 bash. when use command: netstat -tnpl | grep "tcp" | awk '{print $4}' ,than output following: 127.0.0.1:2208 0.0.0.0:871 0.0.0.0:9001 0.0.0.0:3306 0.0.0.0:111 127.0.0.1:631 127.0.0.1:25 127.0.0.1:6010 127.0.0.1:6011 127.0.0.1:2207 :::80 :::22 :::8601 ::1:6010 ::1:6011 :::443 but when use this: ip_port=`netstat -tnpl | grep "tcp" | awk '{print $4}'` && echo $ip_port ,it becomes following: 127.0.0.1:2208 0.0.0.0:871 0.0.0.0:9001 0.0.0.0:3306 0.0.0.0:111 127.0.0.1:631 127.0.0.1:25 127.0.0.1:6010 127.0.0.1:6011 127.0.0.1:2207 :::80 :::22 :::8601 ::1:6010 ::1:6011 :::443 it becomes online. how did happen , want original format. you need enclose variable in quotes when echoing: echo "$ip_port" also, don't need use both grep , awk because awk can grep . can simplify command to: netstat -tnpl | awk '/tcp/{print $4}'
