'''uname''' (short for ''unix name'') is a [[computer program]] in [[Unix]] and [[Unix-like]] computer [[operating system]]s that prints the name, version and other details about the current machine and the operating system running on it.

==History==
The <code>uname</code> system call and command appeared for the first time in [[PWB/UNIX]]. Both are specified by [[POSIX]].<ref>[http://pubs.opengroup.org/onlinepubs/9699919799/utilities/uname.html uname]. The Open Group Base Specifications Issue 7/IEEE Std 1003.1, 2013 Edition. Specifies the command.</ref><ref>[http://pubs.opengroup.org/onlinepubs/9699919799/functions/uname.html uname]. The Open Group Base Specifications Issue 7/IEEE Std 1003.1, 2013 Edition. Specifies the function/system call.</ref> The [[GNU]] version of uname is included in the "sh-utils" or "coreutils" packages. <code>uname</code> itself is not available as a standalone program. The version of <code>uname</code> bundled in GNU coreutils was written by David MacKenzie.<ref>{{man|1|uname|Linux}}</ref> The command is available as a separate package for [[Microsoft Windows]] as part of the [[GnuWin32]] project<ref>[http://gnuwin32.sourceforge.net/packages/coreutils.htm CoreUtils for Windows]</ref> and the [[UnxUtils]] collection of [[Native (computing)|native]] [[Windows API|Win32]] [[porting|ports]] of common GNU Unix-like utilities.<ref>[http://unxutils.sourceforge.net/ Native Win32 ports of some GNU utilities]</ref>

==Related and similar commands==
* Some Unix variants, such as [[AT&T Corporation|AT&T]] [[UNIX System V]] Release 3.0, include the related <code>setname</code> program, used to change the values that uname reports.
* The <code>[[ver (command)|ver]]</code> command found in operating systems such as [[DOS]], [[OS/2]] and [[Microsoft Windows]] is similar to the <code>uname</code> command.
* The [[Bash (Unix shell)|bash]] shell provides the special variables <code>OSTYPE</code> and <code>HOSTTYPE</code> whose values are similar to those of <code>uname -o</code> and <code>uname -m</code> respectively.

==Examples==
On a system running [[Darwin (operating system)|Darwin]], the output from running <code>uname</code> with the <code>-a</code> [[command-line argument]] might look like the text below:
<syntaxhighlight lang="console">
$ uname -a
Darwin Roadrunner.local 10.3.0 Darwin Kernel Version 10.3.0: Fri Feb 26 11:58:09 PST 2010; root:xnu-1504.3.12~1/RELEASE_I386 i386
</syntaxhighlight>

The following table contains examples from various versions of <code>uname</code> on various platforms.<ref>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.</ref>
