Deleting content of folder with shell script
提问by Antonio MG
Im having problems trying to empty a folder in my script.
我在尝试清空脚本中的文件夹时遇到问题。
This is working in my command line:
这在我的命令行中有效：
rm -r Folder1/Folder2/*
But if in my script I do this:
但是如果在我的脚本中我这样做：
DIR="Folder1/Folder2/"
rm -r "$DIR*"
It says "rm: Folder1/Folder2/*: No such file or directory", where is the problem?
它说“rm：Folder1/Folder2/*：没有那个文件或目录”，问题出在哪里？
Im running the script in the same folder as I tried the command.
我在尝试命令时在同一文件夹中运行脚本。

Glob expansion doesn't happen inside quotes.
全局扩展不会发生在引号内。
Try:
尝试：
rm -r -- "$DIR"*
(Just make really sure you don't put a space after the quotes.)
（只要确保不要在引号后放置空格。）

rm -r $DIR*
That should work, without quotes
这应该有效，没有引号
