如何使用 find 实用程序匹配文件 *.R 和 *Rd? [英] How to match files *.R and *Rd with find utility?

问题描述

我想查找所有以 .c、.R 或 .Rd 结尾的文件.我试过了

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 或 .R 结尾的文件.我怎样才能另外获取 .Rd 文件?我知道 [] 只匹配一个字符，但我无法调整它以提供 .Rd 文件(尝试使用 | 或选项 -regex 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

给你=)

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

如果它只是您正在寻找的 3 种扩展类型，我建议您远离正则表达式，而只使用 -o(如or")运算符来组成您的搜索.

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.
