uname (short for unix name) is a computer 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.

[1][2] The GNU version of uname is included in the "sh-utils" or "coreutils" packages.

The version of uname bundled in GNU coreutils was written by David MacKenzie.

[3] The command is available as a separate package for Microsoft Windows as part of the GnuWin32 project[4] and the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.
