Hash keys _can_ contain spaces:
$ perl -Mstrict -Mwarnings -le 'my $key=q(<with spaces >); \
my %h=($key=>q(<value>)); print %h'
and if you have multiple values to one key,
you can use an arrayref as hash value to accumulate the values:
push @{$hash{$displayname}}, $emailaddress;
# instead of
$hash{$displayname}=$emailaddress;
But if you simply want a sorted display of the lines:
print sort @lines;
This would sort by display name on the first level, and for convenience also
by address on the second.
But the easiest way may be to simply sort in the shell:
$ app_printing_the_ldap_lines_to_STDOUT | sort
Hope this helps.
