[Linux 文章收集] Linux 要如何查看作業系統是 32bits 還是 64bits?

轉載自 這裡
系統如何判斷 32bits / 64bits :
一般都是用 uname -a, uname -m (顯示 i386 => 32bits, x86_64 => 64bits)

$ uname -a
Linux ubuntu 2.6.32-41-generic #88-Ubuntu SMP Thu Mar 29 13:10:32 UTC 2012 x86_64 GNU/Linux # 為 64bits

或者可以使用命令 `file /bin/bash`. 結果非常淺顯易懂 :
- 64bits

$ file /bin/bash
/bin/bash: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

- 32bits

# file /bin/bash
/bin/bash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
