How can I determine Linux operating system detail?
uname (short for unix name) is a software program in Unix and Unix-like computer operating systems that prints the name, version and other details about the current machine and the operating system running on it.
Linux users should type the “uname” command. Depending on the platform, you may see
[~]$ uname -a
Linux <username> 2.6.11-1.27_FC3 #1 Tue May 17 20:24:57 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
[~]# uname -a
Linux <username> 2.6.18-194.el5xen #1 SMP Fri Apr 2 15:34:40 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
where,
-a: Print all information, in the following order, except omit -p and -i if unknown.
-p, –processor: Print the processor type or “unknown”
-i, –hardware-platform: Print the hardware platform or “unknown”
