About uname
Print name of current system.
Syntax
uname [-a] [-i] [-m] [-n] [-p] [-r] [-s] [-v] [-X] [-S
systemname]
| -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
<sys/utsname.h>. Only the super-user is allowed
this capability. |
