How can I keep quotes in Bash arguments?

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

Example:

./test.sh this is "some test"

Then I want to use those arguments, and reuse them, including quotes and quotes around the whole argument list.

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

How do I accomplish this?

Solution

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

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

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

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

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

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 $@
echo "$@"

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