3、硬盘的大小信息

diskinfo /dev/rdsk/c2t1d0

SCSI describe of /dev/rdsk/c2t1d0:

vendor: HP 73.4G

product id: ST373454LC

type: direct access

size: 71687369 Kbytes

bytes per sector: 512

4、硬盘的个数

# ioscan -funC disk

Class I H/W Path Driver S/W State H/W Type Description

============================================================================

disk 0 0/0/2/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-N

/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0

disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC

/dev/dsk/c2t0d0 /dev/dsk/c2t0d0s2 /dev/rdsk/c2t0d0 /dev/rdsk/c2t0d0s2

/dev/dsk/c2t1d0s1 /dev/dsk/c2t1d0s3 /dev/rdsk/c2t1d0s1 /dev/rdsk/c2t1d0s3

5、查看操作系统版本和license

# uname -a

HP-UX hp B.11.23 U ia64 0981954047 unlimited-user license

6、如何查看内存

# dmesg

Oct 18 16:47

Found adjacent data tr. Growing size. 0x3448000 -> 0x7448000.

Pinned PDK malloc pool: base: 0xe000000100bb8000 size=119072K

Loaded ACPI revision 2.0 tables.

MMIO on this platform supports Write Coalescing.

Memory Information:

physical page size = 4096 bytes, logical page size = 4096 bytes

Phyhical: 4173976 Kbytes, lockable: 2945984 Kbytes, available: 3427740 Kbytes

7、如何查看文件系统

# bdf

Filesystem kbytes used avail %used Mounted on

/dev/vg00/lvol3 524288 263144 259144 50% /

/dev/vg00/lvol1 311296 77696 231816 25% /stand

/dev/vg00/lvol4 212992 8496 202904 4% /tmp

/dev/vg00/lvol6 4784128 2559584 2207176 54% /opt

/dev/vg00/lvol5 32768 8648 23936 27% /home

存在两个文件中：/etc/fstab /etc/mnttab

27、重新启动机器

#reboot

#shutdown

28、关闭机器

#shutdown -hy 0

#init 0

28、unix的集中运行的模式

多用户模式，但用户模式等等6种。

用如下命令可以看看它的运行模式：

#who -r

. run-level 3 Oct 15 14:34 3 0 S

29、普通的对话

#wall "hello!" (广播hello这个消息)

#banner "hello!"(放大hello这个消息)

#banner "hello!"|more (放大hello消息后再来广播它)

30、看当前的登录名

#logname

root

31、看所有登录用户

#whoiam #whoiam

32、看登录用户在干什么

#whodo

Mon Oct 18 17:24:14 EAT 2010

HP-UX

root 0 Oct 18 16:38

14989 0:00 sh

root 1 Oct 18 17:18

15168 0:00 sh

15234 0:00 whodo

15239 0:00 awk

15240 0:00 sort

15242 0:00 awk

15245 0:00 ps

root console Oct 18 12:47

14124 0:00 sh

33、看看进程

ps -ef|grep root (看root用户的进程，有时候console上执行的进程

够停止的话，那么就将console进程进程杀死，因为该进程是其它进程?

父进程。)
