怎么查看系统是32位还是64位的？

chonaswd

getconf LONG_BIT

selfrun

＃include <stdio.h>
int main()
{
    printf("this is %d bit system", sizeof(void *) * 8);
    return 0;
}

biglazybug

uname 或者cat /proc/cpuinfo

i.am

＃include <stdio.h>
int main()
{
    printf("this is %d bit system", sizeof(void *) * ;
    return 0;
}

很好很强大 呵呵

3.查看操作系统位数

[oracle@svr15 ~]$ ls / #如果有lib64或这个目录,那操作系统就是64位的
bin boot dev etc home initrd lib lost+found media misc mnt opt proc root sbin selinux srv sys tmp usr var

[oracle@svr15 ~]$ getconf LONG_BIT
32

[oracle@svr15 ~]$ ldd /sbin/mii-tool
libc.so.6 => /lib/i686/libc.so.6 (0x00b2f000)
/lib/ld-linux.so.2 (0x00a49000)
