Bang Executing Perl Scripts

Bang Executing Perl Scripts

[zzapper]

Hi
Until now I've been writing zsh wrappers for my perl scripts:-

I've got
alias -s pl=perl
So I can execute a script just by typing its name

> /usr/local/bin/info.pl

But I want to execute it from anywhere , but it doesn't seem to notice perl 
scripts even if they are in my $path or $fpath

I can however do:-

>=info.pl

Is there a better way

And finally I'd really like to execute it just with

>info

Hi,
Why not putting #!/usr/bin/perl as the first line of your perl scripts?

It is already.

BTW I've found that I can do

>=info

Which is pretty much good enough for me!

( and also my script isn't actually named info I just chose that as an 
example, a bad example as of course info already exists as a man reader )

This is not portable.
BeOS and Haiku do not have /usr for ex, so perl is elsewhere.
(and so is env, so using #!/usr/bin/env perl is just moving the problem around)

Perhaps a better solution is to leave the shebang (#!/usr/bin/perl) out 
of your Perl scripts; ensure that perl appears in your path and run your 
scripts via:

% perl myscript.pl

Be sure to add execute privs to each Perl script.

Further, you could create a zsh function to prepend each Perl script 
with "perl " so that you only need type:

% myscript.pl
