You can always use sed to remove all blanks and all leading, trailing whitespace and tabs:
Code:
cat filename | sed '/^$/d;s/^[ \t]*//;s/[ \t]*$//'
cat filename | sed '/^$/d;s/^[ \t]*//;s/[ \t]*$//' > new.filename.txt
Here is your output for php:
PHP Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Upgrading to Pivot 1.40: checking for changes..</title>
</head>
<body>
<h1>Upgrading to blabla for changes..</h1>
<p><em>Version 1.6</em></p>
<p>From blabla other things. </p>
<p>This simple script checks if you've made the required change backup it first. You never know when you might need it. </p>
<p><strong>Note:</strong> Make sure this file is in your <tt>pivot/</tt> folder. Otherwise it'll give incorrect results!</p>
<?php
if (!file_exists(dirname(__FILE__)."/pv_core.php")) {
die("<strong>This script should be placed in your Pivot directory.</strong>");
}
include_once("pvlib.php");
load_all_templates();
echo "<h2>Getting rid of miscellaneous old unused files/directories</h2>";
$filestocheck = array(
"./includes/calendar.php"
);
foreach ($filestocheck as $filetocheck) {
if (filepresent($filetocheck)) {
warn("The file <tt>$filetocheck</tt> is still present. You should remove it.");
} else {
pass("The file <tt>$filetocheck</tt> is not present.");
}
}
