Mac OS X常用命令

1.sw_vers查看系统版本号(在无法点击查看本机时可以使用命令查看系统版本号,曾遇到的问题 在虚拟机里面无法点击查看本机看系统版本号):

xiaqiangdeMacBook-Pro:~ xiaqiang$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.11.6
BuildVersion:   15G31

2.sw_vers | grep ‘ProductVersion:’ | grep -o ‘[0-9].[0-9].[0-9]*’ 直接过滤出版本号:

xiaqiangdeMacBook-Pro:~ xiaqiang$ sw_vers | grep 'ProductVersion:' | grep -o '[0-9]*\.[0-9]*\.[0-9]*'
10.11.6

4.man sysctl查看相关命令的使用方法:

xiaqiangdeMacBook-Pro:~ xiaqiang$ man sysctl

-o      Show opaque variables (which are normally suppressed).  The for-
mat and length are printed, as well as a hex dump of the first
sixteen bytes of the value.

-q      Suppress some warnings generated by sysctl to standard error.

-X      Equivalent to -x -a (for compatibility).

-x      As -o, but prints a hex dump of the entire value instead of just
the first few bytes.
