在linux终端输入 getconf LONG_BIT 命令
如果是32位机器,则结果为32
- [root@localhost ~]# getconf LONG_BIT
- 32
- [root@localhost ~]# getconf LONG_BIT
- 64
如果是64位机器,会输出x86_64
- [chenzhou@testweb01 ~]$ uname -a
- Linux testweb01 2.6.18-308.4.1.el5 #1 SMP Tue Apr 17 17:08:00 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
- [root@localhost ~]# uname -a
- Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux
示例:32位机器
