linux 下查看cpu信息

linux 操作系统的位数查看

A. getconf LONG_BIT 如果是32表示是32位

B.  file /sbin/init信息全面一些

root@kali:~/software# file /sbin/init
/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xb137367bf955d6ab9e17a1395b8768cbc1603e58, stripped

c. uname -a

root@kali:~/software# file /sbin/init
/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xb137367bf955d6ab97a1395b1768cbc1603e58, stripped

d. 还有这两条指令，结果不一样》》》

root@kali:~/software#  echo $HOSTTYPE
i486
root@kali:~/software# uname -m
i686
root@kali:~/software# 

e.  AIX查看硬件cpu位数和os位数

显示机器硬件是32位还是64位

# bootinfo -y
64

查看aix操作系统是32位还是64位

# bootinfo -K
64

f. 查看cpu物理信息，过于全面了

root@kali:~/software# dmidecode | more
