方法一:
file /sbin/init 或 file /bin/ls
結果如下
[root@localhost ~]# file /sbin/init
/sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
[root@localhost ~]# file /bin/ls
/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
如果顯示爲32bit爲32位,64bit則爲64位。
方法二:
[root@localhost ~]# uname -a
Linux localhost.lw 2.6.32-358.el6.i686 #1 SMP Thu Feb 21 21:50:49 UTC 2013 i686 i686 i386 GNU/Linux
顯示x86_64表示爲64位,i686則爲32位。
方法三:
[root@localhost ~]# getconf LONG_BIT
32
直接看顯示結果
