Bash Globbing/通配

Bash语言不支持正则表达式，而是通配的使用方式。sed awk 等工具支持正则表达式。

Bash itself cannot recognize Regular Expressions. Inside scripts, it is commands and utilities – such as sed and awk – that interpret RE’s.

Bash does carry out filename expansion [1] – a process known as globbing – but this does not use the standard RE set. Instead, globbing recognizes and expands wild cards.
