Hallo, this script is thought to be a first step of building a file importing routine. But it is not (entirely) working. I have a list of IDs written into a text file. The script should scan a directory and search for alle the filenames, which contain the ID, listed in the text file. It works, if I define the array with the listed IDs directly into the script, but not, if I open and read the text file. I'm working with cygwin on WinXP

! /usr/local/bin/perl   -w

#Skript searches for filenames in a spec. directory
#referring to a text file which contains a list of Ids

$dir = $ARGV[0]; 

#Scan a directory and write filenames into an array
opendir (SOURCE, $dir)or die "Cannot open dir: $!\n";
         foreach $file (readdir SOURCE) {
         push (@dirFile, $file);     #more than 6000 filenames
         }
closedir SOURCE;

#Open a filehandle and read a list from a text file
$ref = "indexDS.txt";
open(FH, $ref) or die "Cannot open file: \n$!";
@ds = <FH>;
close (FH);

chomp @dirFile;
chomp @ds;        
        
#Test: it works if array is defined like this:
#@ds = ("I C 7702", "I C 7710", "I C 7713");    

#Search for element of @ds as regex in @dirFile
foreach $line (@ds) {
        @result = grep (/$line/, @dirFile); 
        foreach (@result) {
        print "$_\n";
        }
}
