If you were looking for something listening on port 80, for instance: > [root at server ~]# fuser -n tcp 80 > 80/tcp: 3420 3718 3719 3721 3722 3723 3725 3726 3727 > [root at server ~]# The banner ( "80/tcp:" ) is sent to STDERR and the actual PIDs to STDOUT, so you could do something like this: > for procpid in $( fuser -n tcp 80 2>/dev/null ) > do > kill ${procpid} > done fuser requires root access.
