In the NMAP program, if you are running a port scan which switch will save your output to the different formats, .nmap, .xml, and .gmap?

In the NMAP program, if you are running a port scan which switch will save your output to the different formats, .nmap, .xml, and .gmap?

EXPLANATION

In the NMAP port scanner, you can save your portscan as a nmap file, xml file, and a gmap file . If you want to save your one of each you can use the -oA switch. The gmap file extension can come in handy as this is a grepable file. If you were going to scan a network with the command nmap -p-oA initial 10.0.0.0/24 you could use the grep command to find a host in the network utilizing a specific port. Perhaps your goal is to find FTP servers. In this case you might run the command grep output.gmap for the ftp service.
