有幾個簡單、有用的指令，可以很容易的知道SUN Solaris 作業系統的資訊，例如是 32-bit 或 64-bit 版本。
1.機器是否支援64-bit的作業系統?
目前Sun的機器只要是屬於UltraSPARC平台的話，就是有支援64-bit的作業系統。

$/bin/uname -m
sun4u

2.知道所執行的作業系統版本是32-bit 或 64-bit?

$/bin/isainfo -v
64-bit sparcv9 applications
32-bit sparc applications

以上訊息表示，它是執行 64-bit 的，否則它會只出現32-bit那一行而已。

3.顯示現行系統相關訊息:

$/bin/showrev -s apsvr01
Hostname: apsvr01
Hostid: 84xx829x
Release: 5.10
Kernel architecture: sun4u
Application architecture: sparc
Hardware provider: Sun_Microsystems
Domain:
Kernel version: SunOS 5.10 Generic_120011-14

4.系統安裝了多少的記憶體數量?

$/usr/sbin/prtconf | head -2
System Configuration:  Sun Microsystems  sun4u
Memory size: 4096 Megabytes

5.知道CPU的速度及數量:

$psrinfo
