Hi Chris,

Thanks for the reply.

I would love to do this only problem is that the 2 variables

$NEWSTORE and $NPASS, will be generated from a file that may have
special characters in it ie !"£$%^&* etc, so what i need sed to do is
read the variable in and ignore any special character that are in that
variable.

Is there a way round this at all?
