問題 1
What option of uname displays the version of the running operating system'? (Specify ONLY the option name without any values or parameters.)
正解：
-v Explanation In FreeBSD, theunamecommand is used to display system information. The option-vspecifically displays the version of the running operating system. This information is critical for system administrators and users who need to know the exact version of the OS they are working with, particularly when troubleshooting, updating, or configuring the system for specific software requirements. https://man.freebsd.org/cgi/man.cgi?query=uname&sektion=1&format=html The -v or --version option of the uname command displays the version level of the operating system. This is a string that identifies the release date and patch level of the system. For example, on FreeBSD, the output would be something like: FreeBSD 13.0-RELEASE-p4 #0: Tue Aug 24 07:12:34 UTC 2021 This indicates that the system is running FreeBSD 13.0, with the fourth patch applied, and that the kernel was built on August 24, 2021. The version level can be useful to determine the compatibility and security of the system, as well as to report bugs or issues.
