1、检测系统能否运行基于 Compiz 的 Unity 3D 界面的指令 $ /usr/lib/nux/unity_support_test -p OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile x86/MMX/SSE2 OpenGL version string: 3.0 Mesa 9.0 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes
2.查看系统是32位还是64位有两种方法：查看long的位数，返回32或64;查看文件信息，包含32-bit就是32位，包含64-bit就是64位 $ getconf LONG_BIT $ file /sbin/init 3.统计文件夹下的文件数 $ ls -l | grep "^-" | wc -l 或 $ find ./ -type f | wc -l(责任编辑：IT) |
