Grey Fox,
Glad you got some good ideas from this thread!
I thought something was weird with the missing semicolon - just a small detail.
As far as sorting goes print "$name\n"; #push to DB or whatever here... is where you can just push to a list like @full_names.
Here is one way of many to do the sort. Note that the "Boop" family winds up in the correct sort order.
#!/usr/bin/perl -w
use strict;
my @names =
(
"Builder,Bob",
"Stein,Franklin",
"Boop,Elizabeth",
"Boop,Albert",
"Bear,Izzy",
"SomeGuy,Guy",
"Einstein,Albert",);
@names = sort by_last_name @names;
print join("\n",@names),"\n";
sub by_last_name
{
my ($a_last, $a_first) = split (/,/,$a);
my ($b_last, $b_first) = split (/,/,$b);
$a_last cmp $b_last
or
$a_first cmp $b_first
}
__END__
Prints:
Bear,Izzy
Boop,Albert
Boop,Elizabeth
Builder,Bob
Einstein,Albert
SomeGuy,Guy
Stein,Franklin
I added the simple code to sort by first name.
#!/usr/bin/perl -w
use strict;
my @names =
(
"Builder,Bob",
"Stein,Franklin",
"Boop,Elizabeth",
"Boop,Albert",
"Bear,Izzy",
"SomeGuy,Guy",
"Einstein,Albert",);
@names = sort by_last_name @names;
print join("\n",@names),"\n";
## Now print sorted by first name ##
print "\nNow sorted by first name\n";
@names = sort by_first_name @names;
foreach my $full_name (@names)
{
my ($last,$first) = split (/,/,$full_name);
print "$first,$last\n";
}
sub by_last_name
{
my ($a_last, $a_first) = split (/,/,$a);
my ($b_last, $b_first) = split (/,/,$b);
$a_last cmp $b_last
or
$a_first cmp $b_first
}
sub by_first_name
{
my ($a_last, $a_first) = split (/,/,$a);
my ($b_last, $b_first) = split (/,/,$b);
$a_first cmp $b_first
or
$a_last cmp $b_last
}
__END__
Prints:
Bear,Izzy
Boop,Albert
Boop,Elizabeth
Builder,Bob
Einstein,Albert
SomeGuy,Guy
Stein,Franklin
Now sorted by first name
Albert,Boop
Albert,Einstein
Bob,Builder
Elizabeth,Boop
Franklin,Stein
Guy,SomeGuy
Izzy,Bear

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
