jsons has asked for the wisdom of the Perl Monks concerning the following question:

Dear PerlMonks,

How can I perform a search on a directory by using only the first part of the directory name?

I am trying to learn this language with a course through a 'toss him into the fire and let him swim' mentality.
I have some experience in VB programming, and have been tasked with updating an existing perl program. I am having a hard time getting around the learning curve.

In my first posting for help it was suggested that I try using globbing to use wildcards. I tried to implement the following:


use File::Glob qw(:globally :nocase);

for ($input{"searchtype"} {
    if (/bid/ | /quot/ | /ezd/) {
        @dir = bsd_glob("$dir*");
    }
    else {
    @dir = $dir
    }

without success... I get the following errors in the error log:

(2)No such file or directory: exec of /var/apache/cgi-bin/cadsearch.cgi failed

client xx.xx.xxx.xx Premature end of script headers: /var/apache/cgi-bin/cadsearch.cgi

More details and code follow.

Any guidance with examples are greatly appreciated.

I need to update a perl program that prints a hyperlink to an autocad drawing. The link will be based on a truck number that the user enters into an html page. That page then posts their entries to this perl script.

This page (cadsearch.cgi) uses another perl page (find_dir_all.pl) that returns a directory to search based on the truck number.

The issue that I am having is that I know only the first part of the directory to search due to inconsistent file naming habits. The first part of the directory will be returned to this program. I need to be able to search for a directory that matches the first part of the directory name.
Example: Joe User searches for truck number 12345. I know that the directory will be something like: BID.12345 Wanna B. Company or Quote.12345 Gonna Geta Truck I know everything up to the end of the number and it will be a unique directory, but I will not know what the customer name added to the end will be. Below is the code that I must update, trimmed down for this posting:
Here is the code that I need to update: 

#!/usr/bin/perl
##!/opt/gnu/bin/perl
#/usr/local/bin/apache/cgi-bin/cadsearch.cgi
#push(@INC,"/cgi-bin");

require "cgi-lib.pl";
use File::Find;
use CGI qw(:standard);
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use Socket;
&ReadParse(*input);


$truck=$input{"truckno"}; #ex: 12345
$searchtype=$input{"searchtype"}; #ex: bid
$dir=`/filesystem/scripts/find_dir_all.pl  $truck $searchtype`;
@dir=("$dir/$truck");
$file=$input{"filename"};
#set variable for new dwg convert web app
$dwgpdf="http://webserver/dwgbpdf/";
#variable for hyperlink
$hlink

# finddepth function to locate directory
for ($i=0;$i<=$#dir;$i++){
    finddepth(\&dwgWanted,$dir[$i]);
}

# wanted sub to locate files
sub dwgWanted{
    $hlink="$File::Find::name" if (/^$file.*$ext2.*/ );
    print $hlink
}

This is the change that I made: 
#Set the default values to be changed by proe/excel/etc
$ext=dwg;
$ext2=DWG;
$truck=$input{"truckno"};
$searchtype=$input{"searchtype"};
$dir=`/depot/systems/scripts/find_dir_all.pl  $truck $searchtype`;

# use globbing to locate directory based on searchtype and truck numbe
+r
for ($input{"searchtype"} {
    if (/bid/ | /quot/ | /ezd/) {
        @dir = bsd_glob("$dir*");
    }
    else {
    @dir = $dir
    }
}

This is the perl script called to get the root directory (find_dir_all.pl): 
#!/opt/gnu/bin/perl
##!/usr/bin/perl
package FindDrw;
use Cwd;

#This program finds the correct subdirectory for a truck number

$truck=$ARGV[0];
$searchtype=$ARGV[1];

#search for sales orders
if ($searchtype='so'){
    if ($truck >= 900000 ) {
        $dir = '/directory_tree/so/900000';
    }
    elseif (300000 <= $truck & $truck < 400000) {
        $dir = '/directory_tree/so/300000/$truck';
    }
    elseif ...
}
#search for bids
elseif ($searchtype='bid'){
    if ($truck < 01000){
        $dir = '/directory_tree/bids/bid.00900/bid.$truck';
    }
    elseif (01000 <= $truck & $truck < 02000) {
        $dir = '/directory_tree/bids/bid.01000/bid.$truck';
    }
    elseif ...
}
#search for quotes
elseif ($searchtype='qot'){
    if (3000 <= $truck & $truck < 4000) {
        $dir = '/directory_tree/quotes/quote.3000/Quote.$truck';
    }
    elseif (4000 <= $truck & $truck < 5000) {
        $dir = '/directory_tree/quotes/quote.4000/Quote.$truck';
    }
    elseif ...
}    

print "$dir";

Re: Searching for directory with partial name

    First, I am not sure how the code you supplied runs at all.

    That said, you could probably find the directory you want sorta like this: 

    
my $n = 12345;

my $qdir;
for (glob "/some/dir/Quote.${n}*") {
    if (-d $_) { $qdir = $_; last; }  # check that it's a directory
}
die "Can't find quote directory" unless $qdir;

      How it runs is a mystery to me, too. I will try the example you gave. Thank you very much.
