Making a perl script executable

Shell Programming and Scripting
1

Hello,

I have a perl program called snp_hwe.pl

I have another program called hwe_test.run which contains the following:

for file in *.inp
 do
 cp $file genotype_counts_c.txt
 ./snp_hwe.exe > $file'.res'
 done

I want to change my perl program to an executable program while changing its extension to .exe so the program hwe_test.run can detect it.

Thank you very much

Changing the extension won't help (that's largely a Windows phenomenon). So, unless you are using Cygwin, ...

Run it explicitly with perl or chmod the file so it is executable.

Yes, I have already done that but when I want to run it with hwe_test.run it doesn't detect the file.

Then, perhaps you forgot the "shebang" inside the script?

#!/usr/bin/env perl

or

#!/usr/bin/perl

(or wherever your Perl binaries live)

It would help if you said which OS you are using, and what the error was exactly.
