如何将反斜杠参数传递给脚本? [英] How to pass backslashes argument to a script?

问题描述

我只想在文本文件中附加一个用户输入参数.我正在使用以下命令:

I just want to append an user input argument in a text file. I'm using the following command:

echo "$2" >> "./db.txt"

希望用户

$ 2 设置路径，例如: D:\ Projects \ MyProject .它写入文件，但没有反斜杠.结果是:

$2 is expected to user to set a path like: D:\Projects\MyProject. It writes to the file, but with no backslashes. The result is:

D:ProjectsMyProject

D:ProjectsMyProject

我在任何地方都找不到解决方法.我尝试使用 -e 或 -E 参数(从这里获取)，但在这种情况下似乎没有什么区别.

I can't find anywhere how to fix that. I've tried using -e or -E params(taken from here) but it doesn't seems to make difference in this case.

推荐答案

您必须在shell中转义反斜杠: \\ ，或将字符串放在引号中.

You have to escape backslashes in the shell: \\, or put the string in quotes.

出于调试目的，请使用 set -x .

For debugging purposes use set -x.
