Linux指令

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
