Actually the error is the unquoted $. Just try it from an interactive shell:

Code:
mute@eeepc:~$ grep \^$prmAttunityUser\= file2
mute@eeepc:~$ grep '^$prmAttunityUser=' file2
$prmAttunityUser=ais
$prmAttunityUser=ais

Single quotes are best for such things unless you expect to expand a variable.
Then you should always quote expansions.
Code:
ret=`grep '^$prmAttunityUser=' file2`
echo "$ret"

$ret now contains two lines. Can you operate with that, or will you need a for-loop?

Code:
mute@eeepc:~$ cat for
#!/bin/sh

grep '^$prmAttunityUser=' file2 | sed 's/^.//' | while read ret; do
	printf "Do something with: [[%s]]\n" "$ret"
done
mute@eeepc:~$ ./for
Do something with: [[prmAttunityUser=ais]]
Do something with: [[prmAttunityUser=ais]]

If you need more help, please say which shell you're programming for.

NAME

     mixerctl.conf -- audio mixer configuration file

SYNOPSIS

     mixerctl.conf

DESCRIPTION

     The /etc/mixerctl.conf file consists of mixerctl(1) variables to set at boot time.  Each line of mixerctl.conf has the following format:

     Set mixerctl to YES in rc.conf(5) to have the variables set at boot time.	Additionally, you can have the settings saved and restored for the
     devices of your choice by listing them in mixerctl_mixers in rc.conf(5).
