对 rm 和 ls 使用正则表达式

问题：

这里发生了什么，我该如何解决？

问题：

当我做：

$ls | grep -P "file[1-9]{3}.txt|file[1-9]{2}.txt"

我得到：

file11.txt
file12.txt
file13.txt
file14.txt
file15.txt
file16.txt
file17.txt
file18.txt
file19.txt
file21.txt
file22.txt
file23.txt
file24.txt
file25.txt
file26.txt
file27.txt
file28.txt
file29.txt
etc.

但是当我这样做时：

$ls | grep -P "file[1-9]{3}.txt|file[1-9]{2}.txt" | xargs -d"\n" rm

我得到：
