for starters you might want to look at the <> operator:
while( <> ) {
}
Will read each file on the command line in sequence, saves you thinking
about it.
If it is Unix it is case sensitive, is this your problem?
Are you actually in the directory? `bin/myscript.pl bin/ABC.txt`
Re: No such file or directory
I am on Windows so it should not be case-sensitive. The script and all
required files in one folder. I pass 2 arguments to the script and can I can
open open the file in the $ARGV[0].
my $ad_clients = shift @ARGV;
open (ADFILE, "<", $ad_clients) or die "Could not open $ad_clients for
reading: $! \n"; # This works fine!
my @ad_clients = ;
close ADFILE;
my %inputclient;
foreach my $supplied (@ARGV){
open (INPUTFILE, "<", $supplied) or die "Could not open $supplied for
reading: $!\n # This does not works! Error: No such file or directory

How do you pass the files to the script?
Using opendir to do it is better I may suggest.

Re: No such file or directory
Still cannot see why Perl complains that Could not open file for reading.
File or directory does exist.
I have modified my script and now using Getopt::Long module instead of the
@ARGV variable. Can someone take a look?
The script is now run with command line options like this:
myscript --master --compare file_name --compare another_file
Here is a section of the script
use strict;
use warnings;
#use diagnostics;
use Getopt::Long;
use constant DEFAULT_REPORTDIR => ".\\compare_report";
my $master_list = "";
my @compare_lists = "";
my $help = "";
Getopt::Long::Configure ("ignorecase");
GetOptions(
"master=s" => \$master_list,
"compare:s" => [EMAIL PROTECTED],
"help|?!" => \$help,
);
usage() if $help;
@compare_lists = split(' ',join(' ',@compare_lists));
foreach (@compare_lists){
die "File $_ does not exist or it's empty. Please check the file try
again.\n" unless -s $_;
}
#foreach (@compare_lists){print "$_\n";} # This prints the CLI arguments
correctly.
#
my $outputdir = DEFAULT_REPORTDIR;
unless (-d $outputdir){
mkdir ($outputdir) or die "could not create dir for $outputdir: $!\n";
}
# Read the master list and populate our array.
open (MASTERFILE, "<", $master_list) or die "Could not open $master_list for
reading: $!\n";
my @master_clients = ;
close MASTERFILE;
##
#print "master list starts below:\n";
#foreach (@master_clients){print "$_\n";}exit;
##
my (%inputclient,$list);
# Read the other files and compare the content to the master client list.
foreach $list (@compare_lists){
# Output file name set of element curerently processed.
# Open file to read from.
open(INPUTFH, "<", $list) or die "Could not open $list for reading:
$!\n"; # Could
not open file for reading. File or directory does exist.
while (){
chomp;
$inputclient{"s_"} = $_;
}
close INPUTFH;
#$outputfile = "NOT_IN" . "$outputfile";
my $outputfile = $list;
my (@missing_clients, %outputclient);
open (OUTPUTFILE, ">", $outputfile) || die "Could not open $outputfile:
$!\n";
foreach my $aditem (@master_clients){
push (@missing_clients, $aditem) unless exists $inputclient{"$aditem"};
}

Re: No such file or directory exists
I run my scripts on both linux and windows and never got this problem.. Always edited with notepad or wordpad. I run them from the command line or by choosing "open with -> perl" directly on the file with my win2k. I really don't know what was causing the problem... but IMO the "no such file exists" means that it's not found.. if it was the ^M that would mean the file was found, and then an error would maybe occur when reading it..
