如何在 Bash 参数中保留引号? [英] How to keep quotes in Bash arguments?

问题描述

我有一个 Bash 脚本，我想在传递的参数中保留引号.

I have a Bash script where I want to keep quotes in the arguments passed.

示例:

./test.sh this is "some test"

然后我想使用这些参数，并重新使用它们，包括整个参数列表周围的引号和引号.

then I want to use those arguments, and re-use them, including quotes and quotes around the whole argument list.

我尝试使用 "$@"，但这会删除列表中的引号.

I tried using "$@", but that removes the quotes inside the list.

我该如何实现?

推荐答案

只需在带有双引号的字符串周围使用单引号:

Just use single quotes around the string with the double quotes:

./test.sh this is '"some test"'

所以单引号里面的双引号也被解释为字符串.

So the double quotes of inside the single quotes were also interpreted as string.

但我建议将整个字符串放在单引号之间:

But I would recommend to put the whole string between single quotes:

 ./test.sh 'this is "some test" '

为了理解 shell 正在做什么或者更确切地说是解释脚本中的参数，你可以写一个这样的小脚本:

In order to understand what the shell is doing or rather interpreting arguments in scripts, you can write a little script like this:

#!/bin/bash

echo $@
echo "$@"

然后你会看到并测试，用不同的字符串调用脚本时会发生什么

Then you'll see and test, what's going on when calling a script with different strings
