Question

I am running a bash script that calls mysql. The password ist not correctly transmitted, I guess I have to escape some special chars, like the hash or the dollar sign?

#!/bin/bash

USER=myuser
PASS="#mypass$"

# ... call mysql

Answer 1

Using "..." is already the correct thing to do, but the $ needs to be escaped (\$) if it isn’t followed by an “invalid” character. However you also need to make sure to always have the variable in quotation marks as well, as in:

somecommand -p "$PASS"
