Unix找到：如何匹配文件* .R和* Rd？ [英] Unix find: How to match files *.R and *Rd?

问题描述

我想找到所有以 .c ， .R 或<$ c $结尾的文件C> .Rd 。我试过

I would like to find all files that end with .c, .R, or .Rd. I tried

find . -iname "*.[cR]" -print

给出所有以<$ c结尾的文件$ c> .c 或 .R 。我怎样才能获得 .Rd 文件？我知道 [] 只能匹配一个字符，但我无法调整它以提供 .Rd 文件（尝试使用 | 或者选项 -regex 等等。）

which gives all files that end with .c or .R. How can I additionally get .Rd files as well? I know that [] only matches one character, but I couldn't adjust it to provide .Rd files as well (tried to work with | or option -regex etc.)

推荐答案

这里你去=）

find -name "*.c" -o -name "*.R" -o -name "*.Rd"

如果是只是你正在寻找的3个扩展类型，我建议远离正则表达式，并使用 -o （如或）运算符来组成搜索相反。

If it's just the 3 extension types that you are looking for, I'd recommend staying away from regex and just using the -o (as in "or") operator to compose your search instead.
