uname
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. The uname system call and command appeared for the first time in PWB/UNIX. Both are specified by POSIX.[1][2]
Some Unix variants, such as AT&T UNIX System V Release 3.0, include the related setname program, used to change the values that uname reports.
The GNU version of uname is included in the "sh-utils" or "coreutils" packages. uname itself is not available as a standalone program.

Examples [edit]
On a system running Darwin, the output from running uname with the -a command line argument might look like the text below:
Darwin Roadrunner.local 10.3.0 Darwin Kernel Version 10.3.0: Fri Feb 26 11:58:09 PST 2010; root:xnu-1504.3.12~1/RELEASE_I386 i386
The following table contains examples from various versions of uname on various platforms.[3] Within the bash shell, the environment variable OSTYPE contains a value similar (but not identical) to the value of uname -o.
