[Pkg-ace-devel] Magic Perl again

[Thomas Girard]

[sorry, content corrected]

Hello all,

I've just realized that the add-magic-perl.sh script prevents mwc.pl and
mpc.pl from working... Attempting to run them here gives me a :
> tgg@aspire:~$ mwc.pl
> /bin/sh: -S: invalid option
> Usage:  /bin/sh [GNU long option] [option] ...
>         /bin/sh [GNU long option] [option] script-file ...
> GNU long options:
>         --debug
>         --dump-po-strings
>         --dump-strings
>         --help
>         --init-file
>         --login
>         --noediting
>         --noprofile
>         --norc
>         --posix
>         --rcfile
>         --restricted
>         --verbose
>         --version
>         --wordexp
> Shell options:
>         -irsD or -c command or -O shopt_option          (invocation only)
>         -abefhkmnptuvxBCHP or -o option

And:
> tgg@aspire:~$ sh -x mwc.pl
> + eval '(exit $?0)'
> ++ exit 00
> + eval 'exec perl -S $0 ${1+"$@"}'
> ++ exec perl -S mwc.pl
> /bin/sh: -S: invalid option
> Usage:  /bin/sh [GNU long option] [option] ...
[...] then like above.

Can someone please confirm this ? (Yes, I also have forgotten the `-w'
flag, but this doesn't change anything to the problem I'm depicting here).

I don't understand why *sh* is complaining about the `-S' flag while it
should have exec'd perl... perlrun(1) didn't help either.

Googling a bit gave me
http://www.inf.bme.hu/~pts/Magic.Perl.Header/magicc.txt, but all I get
from this is an big headache...

The Perl policy here
http://www.debian.org/doc/packaging-manuals/perl-policy/ch-programs.html#s-hash_bang 

recommends using #!/usr/bin/perl, so what is the right thing to do ?

Thanks,

Thomas
