Linux uname command All In One

$ uname -a

# Darwin xgqfrms-mbp.local 21.4.0 Darwin Kernel Version 21.4.0: Mon Feb 21 20:34:37 PST 2022; root:xnu-8020.101.4~2/RELEASE_X86_64 x86_64

uname

$ uname [OPTIONS]...

# print all
$ uname -a
$ uname --all

The options are as follows:
-s, (--kernel-name) - Prints the kernel name.
-n, (--nodename) - Prints the system’s node name (hostname). This is the name the system uses when communicating over the network. When used with the -n option, uname produces the same output as the hostname command.
-r, (--kernel-release) - Prints the kernel release.
-v, (--kernel-version) - Prints the kernel version.
-m, (--machine) - Prints the name of the machine’s hardware name.
-p, (--processor) - Prints the architecture of the processor.
-i, (--hardware-platform) - Prints the hardware platform.
-o, (--operating-system) - Print the name of the operating system. On Linux systems that is “GNU/Linux”
-a, (--all) - When the -a option is used, uname behaves the same as if the -snrvmo options have been given.
