使用 find 定位匹配多个模式之一的文件 [英] Using find to locate files that match one of multiple patterns

问题描述

我试图使用命令 find Documents -name "*.{py,html}" 获取目录中所有 python 和 html 文件的列表.

I was trying to get a list of all python and html files in a directory with the command find Documents -name "*.{py,html}".

然后是手册页:

模式('{}')中的大括号不被认为是特殊的(即 find . -name 'foo{1,2}' 匹配名为 foo{1,2} 的文件，而不是文件 foo1和 foo2.

Braces within the pattern (‘{}’) are not considered to be special (that is, find . -name 'foo{1,2}' matches a file named foo{1,2}, not the files foo1 and foo2.

由于这是管道链的一部分，我希望能够指定它在运行时匹配哪些扩展(无硬编码).如果 find 无法做到，perl one-liner(或类似的)就可以了.

As this is part of a pipe-chain, I'd like to be able to specify which extensions it matches at runtime (no hardcoding). If find just can't do it, a perl one-liner (or similar) would be fine.

我最终想出的答案包括各种废话，而且有点长，所以我将其发布为 一个答案 原来的痒我试图抓挠.如果您有更好的解决方案，请随意修改.

The answer I eventually came up with include all sorts of crap, and is a bit long as well, so I posted it as an answer to the original itch I was trying to scratch. Feel free to hack that up if you have better solutions.

推荐答案

使用-o，表示或":

find Documents ( -name "*.py" -o -name "*.html" )

您需要以编程方式构建该命令行，这并不容易.

You'd need to build that command line programmatically, which isn't that easy.

您使用的是 bash(或 Windows 上的 Cygwin)吗?如果是，您应该可以这样做:

Are you using bash (or Cygwin on Windows)? If you are, you should be able to do this:

ls **/*.py **/*.html

以编程方式构建可能更容易.

which might be easier to build programmatically.
