Bash script in bash variable

Question

I have a bash script that arrives like:

SCRIPT=$(curl .... | parsing...)

echo $SCRIPT > myfile

But when I try to echo it in a file, some parts get evaluated. (Variables are substituted if any are defined, the * character is replaced by all files in the working directory, etc...)

Can I prevent bash from evaluating any content of a variable, while still echoing?

Or else don't even create a variable and use: curl .... | parsing... > myfile — anubhava

Yes, use double quotes for that. I'll demonstrate:

$ x='*'

$ echo $x
..list of files..

$ echo '$x'
$x

$ echo "$x"

Yes, seems to work. There were more quotes involved in the curl code before I simplyfied it and that must have been why double quotes echo didn't work for me then.
