Touch(3p)

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\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";
