Unix:如何删除文件中列出的文件 [英] Unix: How to delete files listed in a file

问题描述

我有一个长文本文件，其中包含要删除的文件掩码列表

I have a long text file with list of file masks I want to delete

示例:

/tmp/aaa.jpg
/var/www1/*
/var/www/qwerty.php

我需要删除它们.尝试rm` cat 1.txt`它说列表太长了.

I need delete them. Tried rm `cat 1.txt` and it says the list is too long.

找到了此命令，但是当我从列表中检查文件夹时，其中一些仍然有文件 xargs rm <1.txt手动rm调用可从此类文件夹中删除文件，因此权限没有问题.

Found this command, but when I check folders from the list, some of them still have files xargs rm <1.txt Manual rm call removes files from such folders, so no issue with permissions.

推荐答案

这不是很有效，但是如果您需要全局模式(例如/var/www/*)，则可以使用

This is not very efficient, but will work if you need glob patterns (as in /var/www/*)

for f in $(cat 1.txt) ; do 
  rm "$f"
done

如果您没有任何模式，并且确定文件中的路径不包含空格或其他怪异的东西，则可以使用xargs，如下所示:

If you don't have any patterns and are sure your paths in the file do not contain whitespaces or other weird things, you can use xargs like so:

xargs rm < 1.txt
