Which of the following commands will print important system information such as the kernel version and machine hardware architecture?
Correct Answer: B,D
Explanation The commands that will print important system information such as the kernel version and machine hardware architecture are uname and arch. The uname command prints system information, such as the kernel name, release, version, machine, processor, hardware platform, and operating system. The arch command prints the machine hardware name, which is equivalent to uname -m. For example, uname -a will print Linux 5.10.0-8-amd64 #1 SMP Debian 5.10.46-4 (2021-08-03) x86_64 GNU/Linux, and arch will print x86_64. The sysinfo command is not a valid Linux command. The lspci command prints information about PCI buses and devices in the system. The info command prints documentation for a given topic or command.
