Uname

In computer software, uname 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.

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.

In GNU systems, uname is included in the sh-utils or coreutils packages. uname itself is not available as a standalone program.
