Hi all,

I am just a beginner using Perl. I am doing one program, which is rather long so I think I should not post all of it here. The problem I have now is the first command in the program: #! /usr/bin/perl -w

I almost finished the program, and I tried it on Cigwin or Perl for Window. It runs fine. But when I try to run it in a "real" Linux, if the first line is "#! /usr/bin/perl -w" it runs well (with a lot of warnings, of course), but if the first line is "#! /usr/bin/perl", it always warns the ": bad interpreter: No such file or directory". I don't understand the problem. In order to temporarily solve, I try "#! /usr/bin/perl -w" with the command "no warnings;" in side the program.

So anybody has met the same situation or has any suggestion to me? In Linux, I am using Perl 5.6.1 built for i686-Linux. In Cygwin I am using Perl 5.8.2, and in Window, Perl 5.8.4.

Thank you.

If the program is not too big could you post it here. Either put it in between the Code tags or upload it as a text file.

Hi LwdSquashman,

Yes, sure. I uploaded the program (s.pl) in txt file (s.txt) and the input file is a.txt. Thank you in advance.

When you say "real linux", are you moving the program from one machine to another? It's possible that the "real linux" machine has perl installed somewhere else other than in /usr/bin/perl, but I don't know why it would work with a -w in that case...

Yes, it is. But it is not a big deal. The path /usr/bin/perl should be /usr/local/bin/perl. I tried it, but it still has the same problem. Besides, I tried many other programs with the path /usr/bin/perl or /usr/local/bin/perl without -w, they work fine! Thanks anyway.
