Perhaps file or directory permissions related to the file being checked
based on the user running the perl script?

Hi Renato,
Welcome to Perl and to the list!
I took a quick run through your code, and it's working fine for me.
Are you calling it with "perl script.pl <filename>"? The behavior you
describe almost sounds like you are not providing the argument when you
call the script.
Hope this was helpful!

Hi, all.
I am a very begginer in PERL starting today in this mailing list! :-)
I will try to work especially with Bioinformatics.
I am trying to verify the existence of a file in PERL; however, is
seems not to work. It always returns "The file $file_seqs does not
exist!!!".
Do you know where I am making a mistake?
<code>
#!/usr/bin/perl
use strict;
my $file_seqs;
$file_seqs = $ARGV[0];
if (!-e $file_seqs) {
print "The file $file_seqs does not exist!!! \n";
exit(0);
}
else {
print "The file $file_seqs exist!!! \n";
}
