1.#uname -a
如果有x86_64就是64位的,没有就是32位的
这是64位的
# uname -a Linux WORKS 2.6.9-11.ELsmp #1 SMP Fri May 20 18:25:30 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
这是32位的
#uname -a Linux backup 2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:58:04 EST 2007 i686 i686 i386 GNU/Linux
注意:Ixxx的全是32位的,有X86—64的全是64位
2.# uname -m
x86_64
3.# arch
x86_64
4.#file /bin/cat
/bin/cat: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped
5.查看cpu是多少位的
more /proc/cpuinfo
怎样查看 LINUX是32位还是64位
$su - root
#file /sbin/init
/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
即是32位的 linux, 如是64位的, 显示的是 64-bit
