uname - will print detailed info about your system
The uname (short for unix name) command will print detailed information about your Linux and Unix-like system and hardware. This includes the machine name, operating system, and kernel. To run this command, simply enter uname in your command line:
Examples:
uname [option]
Some of the options are as follows,
1. The following command prints all the system information:
$ uname -a FreeBSD test-system.cifnet.com 13.0-RELEASE-p7 FreeBSD 13.0-RELEASE-p7 #0: Mon Jan 31 18:24:03 UTC 2022 root@amd64-builder.daemonology.net:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64
2. This command prints the type of the machine processor architecture, in our case it's amd64
$ uname -p amd64
3. And finally the “-n” option prints the system's hostname:
$ uname -n test-system
