regex - 或查找正则表达式中的条件

Question

为什么有文件却不查找？

查找 ./-regex '.*(jar|war)'

Answer 1

有关正则表达式支持的语法的信息，请参阅man find:

-regextype type
       Changes the regular expression syntax understood by  -regex  and
       -iregex tests which occur later on the command line.  Currently-
       implemented types are emacs (this is  the  default),  posix-awk,
       posix-basic, posix-egrep and posix-extended.

这个有效:

$ find . -regextype egrep -regex '(.*jar)|(.*war)'

为避免使用 -regextype 将表达式更改为 emacs 正则表达式:

$ find . -regex '.*\(jar\|war\)'
