Solaris is not the only OS that provides a uname command.

uname --help
Usage: uname [OPTION]...
Print certain system information. With no OPTION, same as -s.
-a, --all print all information, in the following order:
-s, --kernel-name print the kernel name
-n, --nodename h print the network node hostname
-r, --kernel-release print the kernel release
-v, --kernel-version print the kernel version
-m, --machine print the machine hardware name
-o, --operating-system print the operating system
--help display this help and exit
--version output version information and exit

uname -a

uname --help
/bin/uname: illegal option -- -
/bin/uname: illegal option -- h
/bin/uname: illegal option -- e
uname: illegal option -- l
usage: uname [-snrvmapiX]
uname [-S system_name]
If uname is to be patched, the native uname command
needs to be probed and the ksh uname conditionally
compiled based on the results of the probe. The GNU
version of uname supports -o, which is not supported
by Solaris or ksh uname commands. There is also
nothing that prevents spaces from being in the version,
so parsing uname -a is problematic at best.
