3.查看系统位数
1)
leblancs@leblancs-virtual-machine:~$ getconf WORD_BIT 32 leblancs@leblancs-virtual-machine:~$ getconf LONG_BIT 64 leblancs@leblancs-virtual-machine:~$
2)
leblancs@leblancs-virtual-machine:~$ file /bin/bash /bin/bash: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=6587b60b0a57e1a0f83f7523a658e0bf329fdb5f, stripped leblancs@leblancs-virtual-machine:~$
4. 查看gcc版本
leblancs@leblancs-virtual-machine:~$ gcc --version gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005 Copyright (C) 2016 Free Software Foundation, Inc.
