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. The timestamps are read from the reference file when the object is created, not when "<-"touch>> is invoked. Default is undefined.

time => $time

If defined, then this value will be used for both access time and modification time, whichever of those are set. This time is overridden by the "atime" and "mtime" arguments, if you use them.

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\n";

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\n";

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\n";

Make a change to a file, keeping its timestamps unchanged

 use File::Touch;
 my $date_restorer = File::Touch->new(reference => $file);
 # Update the contents of $file here.
 $date_restorer->touch($file);
