You can use glob to get all the files in the directory. Use the -M or -C
or -A file test on the file name to get the

$a and $b are built-in variables used for 'comparison criteria' during the
sort process.
The statement you have posited means that the contents of @files be sorted
alphabetically. The sorting criterion is spelled by $a cmp $b statement.

i am trying to understand this regex that is supposed to make an

1. what are the "." (periods) doing?
2. in the string "\', \'" what is the ","(comma) doing

The periods are string concatenation operators (tying separate strings

When you say sort($a cmp $b) it sorts ascendingly. When you say sort{$b <=>
$a) it sorts descendingly.

Thanks for your answer Bob! 0-)
However, I already had this set up as you describe and I am getting a
"requires explicit package name" error when I try to use a variable from
the module exporting its variables.
There are two differences that I see between what I did and what you show:
hi,
I have the following string
$a =
"buy 10/23/01 100 12.625 50 25.25 \n
buy 10/25/01 100 12.625 50 25.25 \n
buy 09/1/01 100 12.625 50 25.25 \n
buy 1/23/01 100 12.625 50 25.25 \n";
I would like to sort this by the date (ie the second field) in the
above string.
So it looks like this:
$
As a note...
If I specify the variables in the 'use' statement (ie. use SI::env
qw($mysqlhost $mysqluser $mysqluser $mysqlpass $db_prefix die_error);), the
problem goes away.
I thought the idea behind @EXPORT was to not have to do that.
