How to add backslash and double quote to a string in bash -

i need create string in bash \" in string.

specifically, need create string this:

string="{\"name\":\"execute_recipes\", \"args\":{\"recipes\":[$list_of_recipes]}}"

so when echo $string, have receive:

{\"name\":\"execute_recipes\", \"args\":{\"recipes\":[$list_of_recipes]}}

using single quotes around should trick. single quotes don't interpolate special characters.

string='{\"name\":\"execute_recipes\", \"args\":{\"recipes\":[$list_of_recipes]}}'
