Re: Some File::Find woes.

You don't need to use File::Find for this at all. Further, you don't need to use absolute paths, and you don't need to convert "/" to "\". Windows understands "/" in file paths for a long time now.

#!/usr/bin/perl -w
# this code only partially tested

my($dir)    = $ARGV[0] ||'';
my($maxage) = $ARGV[1] ||0; $maxage = int $maxage;

die "Can't operate without a target directory spec.  Op aborted.\n"
   unless length $dir; # dir could be named "0"
die qq[No such directory "$dir"\n] unless -e $dir;
die "Need max allowed age spec for files.  Op aborted.\n"
   unless $maxage; # zero values and non-numeric values not accepted.

local *PDFDIR;
opendir(PDFDIR, $dir) or die $!;
my(@files) = grep(/\.pdf$/, readdir(PDFDIR));
closedir(PDFDIR) or warn $!;

print qq[Nothing to do.  No files present in "dir".\n] and exit unless
+ @files;

foreach (@files) {
   print qq[Skipping directory "$dir/$_"\n] if -d $_;
   unlink $dir . '/' . $_ if int(-M $dir . '/' . $_) > $maxage
      or die qq[Can't unlink "$dir/$_"! $!];
   print qq[Deleted "$dir/$_"\n];
}

print "Done.\n\n" and exit;

if you plan a non-File::Find you'd better make your procedure a recursiv one. my($dir) = $ARGV[0] \|\|''; my($maxage) = $ARGV[1] \|\|0; $maxage = int $maxage; die "Can't operate without a target directory spec. Op aborted.\n" unless length $dir; # dir could be named "0" die qq[No such directory "$dir"\n] unless -e $dir; die "Need max allowed age spec for files. Op aborted.\n" unless $maxage; # zero values and non-numeric values not accepted. sub gothere { my ($ddir) = @_; $ddir=~ s\|$\|/\|; local *PDFDIR; opendir(PDFDIR, $ddir) or die $!; my(@files) = map {$ddir . $_} readdir(PDFDIR); closedir(PDFDIR) or warn $!; print qq[Nothing to do. No files present in "dir".\n] and exit unl +ess @files; foreach my $f (@files) { next if $f =~ /^\.+$/; #don't want . .. gothere($f) if -d $f; if ((int(-M $f) > $maxage) && (-f _) && $f=~/\.pdf$/i) {unlink $f or die qq[Can't unlink "$f"! $!];} print qq[Deleted "$f"\n]; } } gothere($dir); print "Done.\n\n" and exit; [download] warning untested. -- dominix	[reply] [d/l]

Adding a note, of course, that you are assuming the directories they want to search do not contain sub-directories that need searching - which, for this many files though, is very likely to be the case. .02 cLive ;-)	[reply]
