How would you determine the software version from the CLI?

The 'fw ver' command is part of the Check Point fw command set and outputs the exact version string of the installed firewall module. It is the direct, purpose-built command for identifying the software version and is documented in Check Point's CLI reference guides.

fw stat displays the status and name of the currently loaded security policy, not the software version.

fw monitor is a packet capture utility used for traffic analysis and debugging, unrelated to version reporting.

cpinfo is a comprehensive diagnostic data-collection tool used for support escalations; it gathers broad system data rather than simply reporting the software version.
