You forgot to make your script executable, as this demo shows:
$ ls -l /usr/bin/perl
-rwxr-xr-x 2 root root 2478418 Jan 16 2004 /usr/bin/perl
$ rm -f print.pl
$ echo '#!/usr/bin/perl' > print.pl
$ echo 'print "Hello, world\n"' >> print.pl
$ ls -l print.pl
-rw------- 1 anonymous monk 39 Oct 20 11:33 print.pl
$ ./print.pl
bash: ./print.pl: /usr/bin/perl: bad interpreter: Permission denied
$ chmod +x print.pl
$ ls -l print.pl
-rwx------ 1 anonymous monk 39 Oct 20 11:33 print.pl
$ ./print.pl
Hello, world
It's not that your she bang line is wrong as a previous poster suggested. If that was the case, you would get the message:
$ bash: ./print.pl: /usr/bin/perl: bad interpreter: No such file o
+r directory
which you would also get if there were "unreadable" characters after 'perl' as the other posted suggested.
