You don't need awk to do this. Simply read values into variables in while loop:
Code:
while read DBNAME USERNAME PASSWORD
do
     echo "$DBNAME , $USERNAME , $PASSWORD"
done < dblist.txt

BTW the problem with your script is that you are reading lines in variable: line Later you are using cat which is wrong:
Code:
while read line
do
   export DBNAME=`cat dblist.txt | awk '{print $1}'`
   export USERNAME=`cat dblist.txt | awk '{print $2}'`
   export PASSWORD=`cat dblist.txt | awk '{print $3}'`
   echo "$DBNAME , $USERNAME , $PASSWORD"
done < dblist.txt

You should replace it with echo "$line"

NAME
English - use nice English (or awk) names for ugly punctuation variables SYNOPSIS
use English; use English qw( -no_match_vars ) ; # Avoids regex performance penalty # in perl 5.16 and earlier ... if ($ERRNO =~ /denied/) { ... } DESCRIPTION
This module provides aliases for the built-in variables whose names no one seems to like to read. Variables with side-effects which get triggered just by accessing them (like $0) will still be affected. For those variables that have an awk version, both long and short English alternatives are provided. For example, the $/ variable can be referred to either $RS or $INPUT_RECORD_SEPARATOR if you are using the English module. See perlvar for a complete list of these. PERFORMANCE
NOTE: This was fixed in perl 5.20. Mentioning these three variables no longer makes a speed difference. This section still applies if your code is to run on perl 5.18 or earlier. This module can provoke sizeable inefficiencies for regular expressions, due to unfortunate implementation details. If performance matters in your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH, try doing use English qw( -no_match_vars ) ; . It is especially important to do this in modules to avoid penalizing all applications which use them. perl v5.18.2 2014-01-06 English(3pm)
