OS별로 자주 쓰이는 CPU, Memory등의 정보확인 방법에 대한 비교이다.
일부 command는 Root 권한으로 수행되어야 한다.

1. CPU 정보
AIX lsdev -Cc processor
HP-UX ioscan -fnC processor
SOLARIS psrinfo -v
Tru64 psrinfo -v
LINUX cat /proc/cpuinfo

2. Physical RAM
AIX bootinfo -r
HP-UX grep -i Physical /var/adm/syslog/syslog.log
SOLARIS Prtconf
Tru64 uerf | grep memory
LINUX free

3. Kernel Bits
AIX bootinfo -K
HP-UX getconf KERNEL_BITS
SOLARIS isainfo -kv
Tru64 64
LINUX getconf WORD_BIT

4. Service Switch
AIX /etc/netsvc.conf
HP-UX /etc/nsswitch.conf
SOLARIS /etc/nsswitch.conf
Tru64 /etc/svc.conf
LINUX /etc/nsswitch.conf

5. NIC
AIX ifconfig -a
HP-UX lanscan -v
SOLARIS ifconfig -a
Tru64 ifconfig -a
LINUX ifconfig -a

6. Administrator
AIX smit
HP-UX sam
SOLARIS admintool
Tru64 　
LINUX linuxconf
