Linux 要如何查看作業系統是 32bits 還是 64bits?

一般都是用 uname -a, uname -m (顯示 i386 => 32bits, x86_64 => 64bits)

系統如何判斷 32bits / 64bits

在嘿嘿星期四的討論學到, Mat: 用 `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), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

感謝 sshsiung 提供的方法:

• getconf LONG_BIT # 32bits
  

  32

• getconf LONG_BIT # 64bits
  

  64
