Hi,  
Is there a way to execute these two commandes on one line?:

```nohighlight
netstat -Aan | grep LISTEN |awk '{ print $1}'

```

And give the output as parameter to rmsock tcpcb

Something like:

```nohighlight
netstat -Aan | grep LISTEN |awk '{ print $1}' | rmsock tcpcb

```

Thanks.

I don't know the specifics of `rmsock` and/or if the order of parameters/switches matter - you'll have to adjust

`rmsock tcpcb "$(netstat -Aan | awk '/LISTEN/{ print $1}' )"`

given the usage message you got, how do you think you need to adjust the command?

In your other case, you can try the long shell command in the given URL.  
The following is an attempt to shorten the command:

```nohighlight
netstat -Aan | grep -w LISTEN | while read sockaddr protocol x x port x; do set -- $(rmsock "$sockaddr" tcpcb | grep socket); test -n "$9" && ps -ef | grep -w "$9"; echo "$port"; done

```

If it does not work, then turn debug mode on with

```nohighlight
set -x

```

and reply with the result.

may be:

```plaintext
rmsock "$(netstat -Aan | awk '/LISTEN/{ print $1}' )" tcpcb
The socket 0xf1000e00143a2808 is being held by proccess 10747994 (sshd).

```

Then it returns only one row. It escapes the others.  
Regards.

maybe (if rmsoxk doesn'take multiple addresses?)

```plaintext
while addr in "$(netstat -Aan | awk '/LISTEN/{ print $1}' )"
do
   rmsock "${addr}" tcpcb
done

```

Thank you.

Thanks.  
for addr in "$(netstat -Aan | awk '/LISTEN/{ print $1}' )"

Again just one row.

</div>

then `netstat -Aan | awk '/LISTEN/{ print $1}'` return just ONE value.  
add `set -x` to the top of your script to enable debugging.

Sorry, - remove `"` around `$(netstat -Aan | awk '/LISTEN/{ print $1}' )`  
My bad....
