Perl's ucfirst() function can do this, e.g.,
$ echo virginia | perl -ne 'print $_, ucfirst';
virginia
Virginia
$
$ perldoc -f ucfirst
=item ucfirst EXPR
=item ucfirst
Returns the value of EXPR with the first character uppercased. This is
the internal function implementing the C<\u> escape in double-quoted strings.
Respects current LC_CTYPE locale if C<use locale> in force. See L<perllocale>.
If EXPR is omitted, uses C<$_>.

The best way that I have found is to use the following
VARIABLE=`echo $VARIABLE|dd conv=lcase 2>/dev/null`
Do a man on dd to see the other useful goodies.
The 2>/dev/null is optional, but does gives a cleaner output.
