NAME

6       File::Find::Rule::Age - rule to match on file age
7

SYNOPSIS

9           # Legacy API
10           use File::Find::Rule::Age;
11           my @old_files = find( file   => age => [ older => '1M' ], in => '.' );
12           my @today     = find( exists => age => [ newer => '1D' ], in => '.' );
13

DESCRIPTION

15       File::Find::Rule::Age makes it easy to search for files based on their
16       age.  DateTime and File::stat are used to do the behind the scenes
17       work, with File::Find::Rule doing the Heavy Lifting.

FUNCTIONS

20   Legacy Interface
21           age( [ $criterion => $age ] )
22
23       $criterion
24           must be one of "older" or "newer", respectively.
25
26       $age
27           must match /^(\d+)([DWMYhms])$/ where D, W, M, Y, h, m and s are
28           "day(s)", "week(s)", "month(s)", "year(s)", "hour(s)", "minute(s)"
29           and "second(s)", respectively - I bet you weren't expecting that.
30
31           The given interval is subtracted from "now" for every file which is
32           checked to ensure search rules instantiated once and executed
33           several times in process lifetime.
34
35       By 'age' I mean 'time elapsed after mtime' (the last time the file was
36       modified) - without the equal timestamp.
37
38           # now is 2014-05-01T00:00:00, start of this years workers day
39           # let's see what has been worked last week
40           my @old_files = find( file => age => [ older => "1W" ], in => $ENV{HOME} );
41           # @old_files will now contain all files changed 2014-04-24T00:00:01 or later,
42           # 2014-04-24T00:00:00 is ignored
43
44   Modern API
45       The modern API provides 12 functions to match timestamps:
46
47                    | before  | until    | since    | after
48          ----------+---------+----------+----------+---------
49           modfied  | mtime < | mtime <= | mtime >= | mtime >
50          ----------+---------+----------+----------+---------
51           accessed | atime < | atime <= | atime >= | atime >
52          ----------+---------+----------+----------+---------
53           created  | ctime < | ctime <= | ctime >= | ctime >
54          ----------+---------+----------+----------+---------
55
56       Each function takes one argument - the referring timestamp. Following
57       representations are supported (in order of check):
58
59       File name
60           The corresponding "mtime", "atime" or "ctime" or the specified file
61           is used to do the appropriate equation, respectively.
62
63           If a relative path name is specified and the current working
64           directory is changed since rule instantiation, the result is
65           undefined.
66
67       seconds since epoch
68           Each's file "mtime", "atime" or "ctime" is compared as requested to
69           given number.
70
71       DateTime object
72           Each's file "mtime", "atime" or "ctime" is compared as requested to
73           given DateTime.
74
75       DateTime::Duration object
76           Each's file "mtime", "atime" or "ctime" is compared as requested to
77           given "now - $duration". "now" is determined at each check again,
78           for same reasons as in legacy API.
79
80       Examples
81
82           use File::Find::Rule;
83           use File::Fine::Rule::Age;
84
85           my $today = DateTime->now->truncate( to => "today" );
86           my @today = find( owned => modified_since => $today, in => $ENV{PROJECT_ROOT} );
87
88           my @updated = find( file => mofified_after => $self->get_cache_timestamp,
89                               in => $self->inbox );
