Netstat AND rmsock

UNIX AIX
1

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

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

And give the output as parameter to rmsock tcpcb

Something like:

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}' )"

Thanks.
I received:
usage: rmsock Addr TypeOfAddr

Regards.

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:

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

set -x

and reply with the result.

may be:

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?)

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

rmsock "${addr}" tcpcb
done

Again just one row.

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....
