Code:
I do not understand how to split a string at whitespace and then get it into an array.

With bash >= 4, if I recall correctly:
Code:
$ _string='a b c'
$ read -a _array <<< "$s"
$ declare -p _array
declare -a _array='([0]="a" [1]="b" [2]="c")'

Otherwise (zsh, bash, ksh93):
Code:
_array=( $_string )

If you need standard code, you can use positional parameters (you may need to save the existing ones first):

Code:
$ set -- $_string
$ # now you have all elements in "$@", single elements
$ # could be accessed using $1, $2 ... etc.

What I am trying to do:
-find files older than 31 days from multiple directories
-store those multiple files into an array based on which directory they are from
-iterate through those arrays and ask the user if there are any files they want to keep
-deleted all the files that the user does not want kept
1. You can find them with a single command: find dir1 dir2 ... -mtime ....
2. Why do you think, you need to do this?
3. You could iterate through the files using a while read loop and do whatever you need to do inside the loop:

Code:
find ... | while IFS= read -r; do #filename is in $REPLY ...

weather::com::finder

Weather::Com::Finder(3pm)				User Contributed Perl Documentation				 Weather::Com::Finder(3pm)

NAME

       Weather::Com::Finder - finder class to search for weather.com location's

SYNOPSIS

	 #!/usr/bin/perl -w
	 use Weather::Com::Finder;

	 # you have to fill in your ids from weather.com here
	 my $PartnerId	= 'somepartnerid';
	 my $LicenseKey = 'mylicense';

	 my %weatherargs = (
	       'partner_id' => $PartnerId,
	       'license'    => $LicenseKey,
	 );

	 my $finder = Weather::Com::Finder->new(%weatherargs);

	 # if you want an array of locations:
	 my @locations = $finder->find('Heidelberg');

	 # or if you prefer an arrayref:
	 my $locations = $finder->find('Heidelberg');

	 foreach my $location (@locations) {
	   print "Found weather for city: ", $location->name(), "
";
	   print "Current Conditions are ",
	     $location->current_conditions()->description(), "
";
	 }

DESCRIPTION

       The usual way to use the Weather::Com module would be to instantiate a Weather::Com::Finder that allows you to search for a location by
       providing a search string or postal code or any other search string that weather.com understands.

       The finder returns an arrayref or an array of locations (depending on how you call the "find()" method). Each location is an object of
       Weather::Com::Location.

CONSTRUCTOR

       new(hash or hashref)

       The constructor takes a configuration hash or hashref as described in the Weather::Com POD. Please refer to that documentation for further
       details.

METHODS

       find(search string)

       Once you've instantiated a finder object, you can perform "find()" calls to search for locations in the weather.com database.

       The "find()" method returns an array of Weather::Com::Location objects if you call it in list context, else an arrayref.

       Returns undef if no matching location could be found.

       See also documentation of Weather::Com and Weather::Com::Location.
