It looks as if you might have managed to save the link's html element from the wiki page instead of saving the shell script that the link points to. Here's how the first few lines of the script should read:
#!/bin/bash

Here's what the link looks like if you inspect the html element:
<!DOCTYPE html>
<html lang="en" dir="ltr" class="client-js">
<head>
<body class="mediawiki ltr sitedir-ltr ns-0 ns-subject page-Scripted_Compilation_on_Linux_Debian_Ubuntu action-view skin-vector">
<div id="mw-page-base" class="noprint"/>
<div id="mw-head-base" class="noprint"/>
<!-- content -->
<div id="content">
<a id="top"/>
<div id="mw-js-message" style="display:none;" class="js-messagebox"/>
<!-- firstHeading -->
<h1 id="firstHeading" class="firstHeading">
<!-- /firstHeading -->
<!-- bodyContent -->
<div id="bodyContent">
Is it possible ?
