I need to find a file using Applescript. Applescript is so slow. Someone on the Apple forums gave me some unix code and it works for the most part. The ls command is really list and not find but when it works, it returns the path to the file instantly, NOT 45 seconds Applescript takes.

anydata::storage::file
AnyData::Storage::File(3pm) User Contributed Perl Documentation AnyData::Storage::File(3pm)NAME
AnyData::Storage::File -- manipulate files with rich warnings
DESCRIPTION
Opens, reads from, writes to, creates and destroys files with numerous
options for error handling, flocking, binmode, etc.
The simplest form is the equivalent of
my $f = AnyData::Storage::File->new(dirs=>@dirs,flock=>1);
my $str1 = $f->adSlurp($file);
for( @dirs ) {
open(IN,$file) or die $!;
}
sub slurp {
local *IN;
local $/ = undef;
}
But, depending on how you set the default behaviour
SYNOPSIS
use AnyData;
my $f = AnyData::Storage::File->new;
$f->set('binmode',1|0);
$f->set('PrintError',1|0);
$f->set('RaiseError',1|0);
$f->set('Trace',1|0);
$f->set('f_dir',$dir|$dir_array)
< input, fail if doesn't exist > output, truncate if exists, create if doesn't >> append, create if doesn't exist +< read/write, fail if
doesn't exist
r = < r+ =
new()
my $f = AnyData::Storage::File->new;
or
my $f = AnyData::Storage::File->new( %flags );
%flags is a hash which can contain any or all of:
f_dir => $directory, # defaults to './' (
binmode => $binmode, # defaults to 0 (doesn't binmode files)
printError => $warnings, # defaults to 1 (print warning on errors)
open_local_file( $fname, $mode );
Mode is one of
a = append open for reading & writing, create if doesn't exist
r = read open for reading, fail if doesn't exist
u = open open for reading & writing, fail if doesn't exist
c = create open for reading & writing, fail if it already exists
o = overwrite open for reading & writing, overwrite if it already exists
Additionally, all modes fail if the file can't be opened. On systems
that support flock, 'r' fails if a shared lock can not be obtained; the
other modes fail if an exclusive lock can't be obtained.
