Bash script telnet to test multiple addresses and ports

Asked by At

I am required to test at least 130 ip addresses and ports. I am hoping to write a bash script such that it reads the ip address and ports from an input file.

I have the following

while read line
telnet $line >> $2
done < $1

This is a crappy code as it cannot determine whether its connected or failed, and I have to rely on its auto escape character to disconnect from a connection.

How can I improvise this such that it updates $2 with the status quickly? I am working on Redhat and do not have netcat or expect installed..
