The FreeBSD kernel is the same as the released version of FreeBSD, and there is no strict version number similar to Linux. Therefore, it is generally recognized only by its release version.For example, 10.0-RELEASE-p1
Hw.model: Intel (R) Xeon (R) CPU X3220 @ 2.40GHzhw.ncpu: 4hw.machine_arch: amd64 My Intel Xeon quad core processor runs at 2.40GHz.You need to use the following command and grep command.FreeBSD uses the dmesg command to view CPUINFO: Type the following command # dmesg | grep - i cpu Or directly query/var/run/dmesg.boot file # grep - i cpu/var/run/dmesg.boot Output: CPU: Dual Core AMD Opteron (tm) Processor 170 (1999.08-MHz 686 class CPU) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu0: on acpi0 acpi_throttle0: on cpu0 cpu1: on acpi0 acpi_throttle1: on cpu1 SMP: AP CPU #1 Launched!You can also dump more information about using the sysctl command
To view the kernel version information of the Linux distribution, one way is to use the uname - a command, which lists the kernel version and whether the system is i686 32-bit or x86_64 64 bit.Another way to view the kernel version is to use cat to display the contents of the/proc/version file: cat/proc/version/The content of the proc/version file is the kernel version information. To check the distribution of your Linux system, you can use the lsb_release - a command. The lsb_release - a command can list the distribution and the specific version of that distribution.
