Apple Portables: How to determine that your portable has a Multi-Touch trackpad
Many Apple portable computers have Multi-Touch trackpads that use gestures to perform tasks such as zooming, rotating images, and even switching applications. These gestures may involve two, three, or four fingers. Available gestures vary based on the Apple portable and operating system.
I currently have a shell script that utilizes the "Date" binary - this application is slightly different on OS X (BSD General Commmand) and Linux systems (gnu date).

Touch(3pm) User Contributed Perl Documentation Touch(3pm)NAME
File::Touch - update access and modification timestamps, creating nonexistent files where necessary.
SYNOPSIS
use File::Touch;
@file_list = ('one.txt','../two.doc');
$count = touch(@file_list);
use File::Touch;
$reference_file = '/etc/passwd';
$touch_obj = File::Touch->new(
reference => $reference_file,
no_create => 1
);
@file_list = ('one.txt','../two.doc');
$count = $touch_obj->touch(@file_list);
DESCRIPTION
Here's a list of arguments that can be used with the object-oriented contruction:
atime_only => [0|1]
If nonzero, change only the access time of files. Default is zero.
mtime_only => [0|1]
If nonzero, change only the modification time of files. Default is zero.
no_create => [0|1]
If nonzero, do not create new files. Default is zero.
reference => $reference_file
If defined, use timestamps from this file instead of current time. Default is undefined.
atime => $time
If defined, use this time (in epoch seconds) instead of current time for access time.
mtime => $time
If defined, use this time (in epoch seconds) instead of current time for modification time.
Examples
Update access and modification times, creating nonexistent files
use File::Touch;
my @files = ('one','two','three');
my $count = touch(@files);
print "$count files updated
";
Set access time forward, leave modification time unchanged
use File::Touch;
my @files = ('one','two','three');
my $day = 24*60*60;
my $time = time() + 30 * $day;
my $ref = File::Touch->new( atime_only => 1, time => $time );
my $count = $ref->touch(@files);
print "$count files updated
";
Set modification time back, update access time, do not create nonexistent files
use File::Touch;
my @files = ('one','two','three');
my $day = 24*60*60;
my $time = time() - 30 * $day;
my $ref = File::Touch->new( mtime => $time, no_create => 1 );
my $count = $ref->touch(@files);
print "$count files updated
";
