The -oA option saves the scan results in all three common output formats at once, using a single base filename. It creates three files: a normal human-readable file, an XML file, and a grepable file, all sharing the same base name. For example, using a base name of scan with a target like 192.0.2.0/24 would produce scan.nmap, scan.xml, and scan.gnmap in the current directory. This is ideal when you want to keep multiple formats for different tools or analysis without running separate commands for each format.
