Always a pleasure to read your posts! Nice way of removing spaces by using arithmetic expansion.

Other benefits of this method are that it also correctly counts file names that contain newlines (whereas ls|wc -l does not) and that there are no command line length limitations..

file::touch
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
";
