#!/bin/sh
perl -I /some/special/libpath:/another/special/libpath "$@"
Drop in an exec to get rid of a needless /bin/sh instance:
#!/bin/sh
exec perl -I /some/special/libpath:/another/special/libpath "$@"
And if you have more than one perl, specify which one you want to start. Also do this if you are not sure what $ENV{'PATH'} may contain.
#!/bin/sh
exec /usr/local/perl-5.42.99/bin/perl -I /some/special/libpath:/anothe
+r/special/libpath "$@"
But then again, cbeckley++ is right, perl can do fine without a shell:
#!/usr/local/perl-5.42.99/bin/perl
use lib '/some/special/libpath','/another/special/libpath';
# rest of the script here, unmodified
Perl does not even mind if you prefix those two lines to an existing script, the shebang (#!) line of the existing script will be parsed as a comment.
If you don't want to modify scripts, you can also use a perl script as a wrapper:
#!/usr/local/perl-5.42.99/bin/perl
use lib '/some/special/libpath','/another/special/libpath';
require '/path/to/real/script.pl';
(untested)
This simple one assumes that script.pl returns a true value. Alternatively, use do $filename, but that needs more code for error handling:
#!/usr/local/perl-5.42.99/bin/perl
use lib '/some/special/libpath','/another/special/libpath';
unless (defined(do '/path/to/real/script.pl')) {
die "Could not parse script: $@" if $@;
die "Could not read script: $!";
}
(untested)
Generally, if you run a script as root or setuid root, consider adding -T to the shebang line to enable taint mode (see perlsec).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
