The safe way to interpolate a variable into a string is to use ${var_name}. For example:

#!/bin/bash

devName="/dev/sda"
devTarget=$devTarget="${devName}33"

echo "$devTarget"

This way Bash has no doubts of what the variable to interpolate is.

Btw, interesting how devTarget=$devName\3 works. I'm not sure why.
