Here is what I found. I can not run
Permisions are set.
>>root@ttyp0[sdb1]# ll
>>-rwxrwxr-x 1 knoppix knoppix 45 Feb 12 08:23 >>

Listing of
>>root@ttyp0[sdb1]# cat
>>print "Hello World! \n";

Try to run it, results are bad.
>>root@ttyp0[sdb1]# ./
>>: bad interpreter: No such file or directory

Test the script via Perl, works.
>>root@ttyp0[sdb1]# perl
>>Hello World!

Script is pointing to correct Perl
>>root@ttyp0[sdb1]# which perl

Any ideas?
