NAME

uname − print name of current UNIX system

SYNOPSIS

uname [ −amnprsv ]
uname [ −S system_name ]

DESCRIPTION

uname prints the current system name of the UNIX system to standard output.  It is mainly useful to determine which system one is using.  The options cause selected information returned by uname(2) and/or sysinfo(2) to be printed:

−a Print all information. 

−m Print the machine hardware name. 

−n Print the nodename (the nodename is the name by which the system is known to a communications network). 

−p Print the current host’s processor type. 

−r Print the operating system release. 

−s Print the name of the operating system (e.g. UNIX System V).  This is the default. 

−v Print the operating system version. 

On the computer, the nodename may be changed by specifying a system name argument to the −S option.  The system name argument is restricted to SYS_NMLN characters.  SYS_NMLN is an implementation specific value defined in sys/utsname.h.  Only the super-user is allowed this capability.
