NAME

6       File::Touch - update file access and modification times, optionally
7       creating files if needed
8

SYNOPSIS

10        use File::Touch;
11        @file_list = ('one.txt','../two.doc');
12        $count = touch(@file_list);
13
14        use File::Touch;
15        $reference_file = '/etc/passwd';
16        $touch_obj = File::Touch->new(
17                         reference => $reference_file,
18                         no_create => 1
19                     );
20        @file_list = ('one.txt','../two.doc');
21        $count     = $touch_obj->touch(@file_list);

DESCRIPTION

24       Here's a list of arguments that can be used with the object-oriented
25       contruction:
26
27       atime_only => [0|1]
28           If nonzero, change only the access time of files. Default is zero.
29
30       mtime_only => [0|1]
31           If nonzero, change only the modification time of files. Default is
32           zero.
33
34       no_create => [0|1]
35           If nonzero, do not create new files. Default is zero.
36
37       reference => $reference_file
38           If defined, use timestamps from this file instead of current time.
39           The timestamps are read from the reference file when the object is
40           created, not when "<-"touch>> is invoked.  Default is undefined.
41
42       time => $time
43           If defined, then this value will be used for both access time and
44           modification time, whichever of those are set. This time is
45           overridden by the "atime" and "mtime" arguments, if you use them.
46
47       atime => $time
48           If defined, use this time (in epoch seconds) instead of current
49           time for access time.
50
51       mtime => $time
52           If defined, use this time (in epoch seconds) instead of current
53           time for modification time.
54

Examples

56   Update access and modification times, creating nonexistent files
57        use File::Touch;
58        my @files = ('one','two','three');
59        my $count = touch(@files);
60        print "$count files updated\n";
61
62   Set access time forward, leave modification time unchanged
63        use File::Touch;
64        my @files = ('one','two','three');
65        my $day = 24*60*60;
66        my $time = time() + 30 * $day;
67        my $ref = File::Touch->new( atime_only => 1, time => $time );
68        my $count = $ref->touch(@files);
69        print "$count files updated\n";
70
71   Set modification time back, update access time, do not create nonexistent
72       files
73        use File::Touch;
74        my @files = ('one','two','three');
75        my $day = 24*60*60;
76        my $time = time() - 30 * $day;
77        my $ref = File::Touch->new( mtime => $time, no_create => 1 );
78        my $count = $ref->touch(@files);
79        print "$count files updated\n";
80
81   Make a change to a file, keeping its timestamps unchanged
82        use File::Touch;
83        my $date_restorer = File::Touch->new(reference => $file);
84        # Update the contents of $file here.
85        $date_restorer->touch($file);
