I have a script which submits a form with wget --post-data

'username=$Uname&password=$Pword' --keep-session-cookies $URL/$AUTHURL 1&>2

During the test with "bash -x" I see the variables are not evaluated and they appear as
$Uname and $Pword. But if I put an echo for testing at top like

echo $Uname

the value is evaluated correctly.
Am I missing something ?

Yes, the single quotes in your wget command which prevent bash from
expanding the variables. Use double quotes instead, see
