Moving Files Based on Date

[moonbug]

How can I move files based on date specifically for the case below:

1. crontab runs every hour
2. any file in directory 1 dated less than the current hour is moved to directory 2.
eg file1 time stamp 2:59
file2 time stamp 2:45
file3 time stamp 2:05
file4 time stamp 3:08
3. crontab runs at 3:15, so file1,2,3 are moved to directory2

Have the cron job call a perl script is quicker/cleaner get stat of each file on the folder(s) and compare the dates to current system time and move it properly

tifoso is right. This is much easier done in Perl than in a shell script. Here's an example:

#! /usr/bin/perl
use strict;
my $destination_directory = '/foo/d2';
foreach my $file (glob "*") {
    my $mtime = (stat("$file"))[9];
    my $now = time();
    my $diff = $now - $mtime;
    print "age of $file is $diff \n";
    # running at x:15 -- 15 minutes = 900 seconds
    if ( $diff > 900 ) {
        print "should move $file to $destination_directory/$file\n";
        #rename $file $destination_directory/$file;
    }
}
 

You would, of course, want to change the value of $destination_directory to whatever is appropriate, uncomment the "rename" line and, of course, you can delete the print statements that just show you what is going on.
