changing a password held in a file -from a script

Hi,
I need to change the password of a application user that is held in a
file called .pass ( shown below), within my script, my script gets
passed either PA_SYBASE,JA_SYBASE,PD_SYBASE plus the new password,
from that I need to , I guess use sed change it.
If I get passed user: PA_SYBASE, I then need to change the entry in
the file p3erth to the new password. I know how to get the correct
line, but I am stuck on how to change the password entry.

Thanks, Pete.

PA_SYBASE_PASSWD=p3erth
JA_SYBASE_PASSWD=jelli0
PD_SYBASE_PASSWD=bron1a

For example (if the file is as shown):

#!/bin/bash

user="${1}_PASSWD"
newpass="${2}"

sed "s/^${user}=.*$/${user}=${pass}/" .pass

Typo: the last line must be

sed "s/^${user}=.*$/${user}=${newpass}/" .pass
