使用循环各种扩展匹配的文件 [英] Matching files with various extensions using for loop

问题描述

我想匹配，遍历文件，扩展名为.txt的.h的.py。在特定的文件夹$ {arg}里。下面是我做的。

I am trying to match and loop through files with extensions .txt .h .py. in specific folder ${arg}. Here is what I did

for file in ${arg}/*.{txt, h, py}; do
  ...

done

但是我没有这样的文件对所有扩展，即使我有这样的文件。

However I got no such file for all extensions even though I have such files.

 line 24: dir1/*.{txt,: No such file or directory
 line 24: h,: No such file or directory
 line 24: py}: No such file or directory

我怎么能循环，虽然使用特定扩展名的文件为？

推荐答案

失去的空间;庆典问津。

Lose the spaces; bash cares.

for file in "${arg}"/*.{txt,h,py}; do
