Uname

Information about Uname

In computer software, uname (stands for Unix Name) is a program in Unix operating systems that prints the name, version and other details about the running operating system. It is useful for building software from source, when certain parameters depend on the host operating system. The uname system call and command appeared for the first time in UNIX System III.

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 Microsoft operating systems such as MS-DOS or Windows is similar to the uname command.

Examples

On a system running Darwin the output from running uname with the -a option might look like the text below: Darwin hostname.local 8.10.1 Darwin Kernel Version 8.10.1: Wed May 23 16:33:00 PDT 2007; root:xnu-792.22.5~1/RELEASE_I386 i386 i386

The following table contains examples from various versions of uname on various platforms. These are merely meant to broadly represent common systems; actual output may vary depending on hardware type, OS version, and which software patches have been installed.
