Escape $ in password

Question

How should I escape special characters in bash

flyway info -url="jdbc:redshift://server_name/db_name?ssl=true&sslfactory=com.amazon.redshift.ssl.NonValidatingFactory" -password='$PROD_PASSWORD'

PROD_PASSWORD=sf45$h)jY*@hj

I want to escape the dollar sign I tried escape \ and putting password='$PROD_PASSWORD' and also password="$PROD_PASSWORD" also %40.

I tried to answer this thoroughly [here](https://askubuntu.com/a/984802/507051). You’re quoting the wrong thing, try `PROD_PASSWORD='sf45$h)jY*@hj'` and `password="$PROD_PASSWORD"`. — dessert, Oct 11 '18 at 22:16
Also, you should first fill the variable and then use it, not the other way around. :) — dessert, Oct 11 '18 at 22:23
it did not work, PROD_PASSWORD='sf45$h)jY*@hj' and password="$PROD_PASSWORD" , my build failed — user_01_02, Oct 11 '18 at 22:27
@user_01_02 just for the record, I suppose this is a dummy password, right? — Agustín Covarrubias, Oct 11 '18 at 22:32

Bash uses single quotes (') to avoid any special characters or the backslash (\) to escape a single character:

MY_VARIABLE='$foo'
echo "$MY_VARIABLE"

This will output $foo as will:

echo '\$foo'

Try to be more specific in answering the question, if possible. That means in this case: use variable names and assignments given in the question to avoid misunderstandings. – ADDB Oct 11 '18 at 22:41
I really don't want to condone such usage of variables or repeat his "production password" anymore to be honest! – Kristopher Ives Oct 11 '18 at 22:56
