Gets information about the system.
Posix requires that assumptions must not be made about the format of the values, e.g. the assumption that a release may contain three digits or anything else returned by this function.
Returns a hash of strings with information about the system. The indices of the hash are sysname - operating system name (e.g. Linux) nodename - system name (e.g. valiant) release - operating system release (e.g. 2.2.10) version - operating system version (e.g. #4 Tue Jul 20 17:01:36 MEST 1999) machine - system architecture (e.g. i586) domainname - DNS domainname (e.g. example.com)
domainname is a GNU extension and not part of POSIX.1, so this field is only available on GNU systems or when using the GNU libc.
The method does not take any parameters
Example #1 Example use of posix_uname()
The above example will output something similar to:
Array ( [sysname] => Linux [nodename] => funbox [release] => 2.6.20-15-server [version] => #2 SMP Sun Apr 15 07:41:34 UTC 2007 [machine] => i686 )
