ports used

rharris72 · 11-22-2005, 08:56 AM

is there a way via bash script that i can get the ports in a range say 12200 13000 that are being used by a user and storing them in a variable

so that when i write the variable to a file it just lists the port numbers used

thanks

Set ipv4 ports of user xxx from p1 to p2 in var

Code:

var=`lsof -n -i4:$p1-$p2 -a -u$xxx | awk '/IPv4/ {print $8}' | cut -d':' -f2 | cut -d'-' -f1 | sort | uniq | tr '\n' ' ' `

Does the trick but very ugly, it should be possible in one regular expression

How about installing "lsof"?

You can use netstat command too, netstat -vatn | grep port
