i've been trying create script take process id number (pid) , identify process id name , list network connections connected to.

i understand should use netstat this. here code far doesn't seem anything, can explain im going wrong , need do?

echo 'please enter process id: ' read pidn echo 'you entered process id: ' $pidn  pid= pgrep -fl "^(/.*)?${pidn}\s" echo $pid

if use command below (ex: ssh)

netstat -nalp | grep -i ssh

follow result:

[root@localhost ~]# netstat -nalp | grep 1055 tcp        0      0 0.0.0.0:22              0.0.0.0:*               listen      1055/sshd tcp6       0      0 :::22                   :::*                    listen      1055/sshd unix  3      [ ]         stream     connected     20308    1055/sshd
