Uname
From Wikipedia, the free encyclopedia
- The correct title of this article is uname. The initial letter is shown capitalized due to technical restrictions.
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. 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.
In GNU systems, uname is included in the "sh-utils" or "coreutils" packages. uname itself is not available as a standalone program.
[edit] Examples
On a system running Darwin the output from running uname with the -a option might look like the text below:
Darwin hostname.local. 6.8 Darwin Kernel Version 6.8: Wed Sep 10 15:20:55 PDT 2003; root:xnu/xnu-344.49.obj~2/RELEASE_PPC Power Macintosh powerpc
