Re: Re: Range of File Names and For/While Problem

[svsingh]

I thought I'd take a quick break from work and see if I could write the File::Find version of this. The following code will create a list of the files modified in the past seven days in d:\log\exported. I didn't backdate the files in my directory to test this thoroughly, but it seems to work.

use File::Find;
my $ageLimit = 7;  # the age (in days) of the oldest file you want to 
+process
my $ageCutoff = time - $ageLimit * (60*60*24); # the cutoff time
my @logFiles = ();
my $findFilter = sub {
   if ( (stat($_))[9] > $ageCutoff ) {  # only push files newer than c
+utoff
      push @logFiles, $_;
   }
   return;
};
find($findFilter, 'd:\log\exported');  # populates the list

Dont forget File::Find is recursive. So youll grab all the files that match in sub directories as well, and should it contain a directory thats new enough you'll have a problem as it'll get included as well. Also as you are simply pushing the base name into the list you wont even know whats happening until you start to diagnose missing files and find them two layers deeper in the file structure :-)

use File::Find;

my @files;
my $age_limit=7;

find {
    wanted=>sub { -f and -M($_) < $age_limit and push @files, $_ },
    no_chdir=>1
}, 'd:\log\exported';

print join("\n",@files),"\n";

You should take a look at find2perl
