[CentOS] Scripting port scans

It kinda looks like he is looking to use return values to do his
scripting....

If so, try netcat.

nc -z -w3 192.168.1.1 80

That will return 0 on open port. 1 on close port. 1 on filtered port.
Waits 3 seconds for a response.
Wrap in a loop as needed...

Use nmap.  Here I'm scanning my home network for any port 80 that's open

nmap -p 80 192.168.1.0/24
