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.
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.
The ver command found in operating systems such as DOS, OS/2 and Microsoft Windows is similar to the uname command.
