glob 匹配规则

glob wiki

1. 语法

最常用的通配符是*, ?,和[...]

Wildcard	Description	Example	Matches	Does not match
`*`	匹配任意数量的字符, 包括空	`Law*`	`Law`, `Laws`, or `Lawyer`	`GrokLaw`, `La`, or `aw`
		`Law`	`Law`, `GrokLaw`, or `Lawyer`.	`La`, or `aw`
`?`	匹配单个字符	`?at`	`Cat`, `cat`, `Bat` or `bat`	`at`
`[abc]`	匹配括号内的字符	`[CB]at`	`Cat` or `Bat`	`cat`, `bat` or `CBat`
`[a-z]`	匹配括号内给的字符范围	`Letter[0-9]`	`Letter0`, `Letter1`, `Letter2` up to `Letter9`	`Letters`, `Letter` or `Letter10`

一般情况下, 路径分隔符(Linux/Unix, MacOS上的/或Windows的\)是从不匹配的,但是一些shell,比如Bash是允许用户规避此问题.

Unix-like

在 Unix-like 系统, 在[...]上有两个附加含义.

Wildcard	Description	Example	Matches	Does not match
`[!abc]`	匹配不在括号内的字符	`[!C]at`	`Bat`, `bat`, or `cat`	`Cat`
`[!a-z]`	匹配不在括号内给的字符范围	`Letter[!3-5]`	`Letter1`, `Letter2`, `Letter6` up to `Letter9` and `Letterx` etc.	`Letter3`, `Letter4`, `Letter5` or `Letterxx`

Bash支持以下扩展:

**: 递归匹配
