In order to solve the problem of space, the 3 of my group have asked all the time, now I know how powerful people, a lot of enthusiastic friends to give me a few solutions, now they give the shell statement sent out:

The code is as follows	Copy Code
NETSTAT-ANTP | grep sshd| Awk-f ":" ' {print $} ' | awk ' {if ($!~/^$/) print $} ' Netstat-ntlp|grep sshd |awk-f: ' {if ($4!= "") Print $} ' Netstat-ntlp|grep ^tcp |awk-f: ' {if ($4!= "") Print $} ' NETSTAT-NTLP | awk '!a[$NF]++ && $NF ~/sshd$/{sub (". *:", "", $);p rint $} ' NETSTAT-ANTP | grep tcp| Awk-f ":" ' {print $} ' | awk ' {if ($!~/^$/) print $} '

OK, just these few, I also lazy, do not want to go over the chat record, can solve the problem on it.
