假定你用的 zsh，看这篇贴子里用到了 zstyle，https://forums.gentoo.org/viewtopic-t-1053122-start-0.html

好像有遇到这个问题，当时也没在意，你这么一说我倒想起来了

@Nitroethane 打错了，是避免使用 cmd+反引号（ iOS 上找了半天没找到这个符号……）

合理是用最小化窗口功能，避免使用 cmd+tab，因为最小化的窗口用 cmd+tab 是切不出来的

In Objective-C when you declare a property @synthesize would create the getter and setters for you automatically since clang 3.2. So, the default @synthesize for a property "foo" would look like this:

@synthesize foo = _foo

because of that _foo would then be the iVar. In other words you could have done the @synthesize yourself and called the iVar whatever you liked:

@synthesize foo = myiVarFoo

so in this case there is no "_"

So now in Swift from the documentation:

Swift unifies these concepts into a single property declaration. A Swift property does not have a corresponding instance variable, and the backing store for a property is not accessed directly.
So from the documentation it's clear that swift does not have a corresponding instance variable thus no need to have the "_" around anymore.

默认情况下新建的文件是会继承所在目录的 security context 。再者，chcon 只是临时修改 security context，作持久改变的话得用 semanage 命令的 fcontext 子命令，具体的可以看 redhat 的文档
