-a Print basic information currently available from the system. -i Print the name of the hardware implementation (platform). -m Print the machine hardware name (class). Use of this option is discouraged; use uname -p instead. -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 ISA or processor type. -r Print the operating system release level. -s Print the name of the operating system. This is the default. -v Print the operating system version. -X Print expanded system information, one information element per line, as expected by SCO UNIX. The displayed information includes: system name, node, release, version, machine, and number of CPUs. BusType, Serial, and Users (set to "unknown" in Solaris) OEM# and origin# (set to 0 and 1, respectively)
-S systemname The nodename may be changed by specifying a system name argument. The system name argument is restricted to SYS_NMLN characters. SYS_NMLN is an implementation specific value defined in . Only the super-user is allowed this capability.
