I wanted a script to show a random quote from bash.org in every new terminal session. PHP is my language of choice. :) Save as “bashquote” and chmod 755 (rwxr-xr-x) to use (make sure the regexp looks exactly as below in preg_match_all()). The script only works in a Unix/Linux environment.
#!/usr/bin/php
<?php
// Use http_proxy environment variable
stream_context_get_default(array('http' => array(
'proxy' => str_replace("http://", "tcp://", getenv('http_proxy')),
'request_fulluri' => true
)));
// Quote cache location
$quotefile = getenv('HOME')."/.bashqdb";
// Only one instance accessing the cache at a time
$fp = fopen("/tmp/bashqdblock.".getenv('USER'),"wb");
if (!flock($fp, LOCK_EX))
die("Couldn't obtain quote file lock!");
// Read cache
$quotes = @file($quotefile, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES | FILE_TEXT);
// If empty (or non-existing), fetch batch of quotes
if (!$quotes)
$quotes = fetchQuotes();
// Select the first quote for display and remove it from array
$quote = $quotes[0];
unset($quotes[0]);
// Massage the text for display
$quote = html_entity_decode($quote);
$quote = str_replace("<br />","\n",$quote);
// Output
echo $quote."\n";
// If that was our last, fetch a new batch
if (count($quotes) == 0)
$quotes = fetchQuotes();
// Write the cache back
file_put_contents($quotefile, implode("\n", $quotes));
// Function for fetching a batch of suitable quotes, returns an array
function fetchQuotes() {
$matches = array();
$source = file_get_contents("http://bash.org/?random1");
preg_match_all("/<p class=\"qt\">(.+?)<\/p>/si", $source, $matches);
$quotes = array();
foreach ($matches[1] as $match) {
$quotes[] = str_replace("\n","",$match);
}
return $quotes;
}
?>

Why did you write it in php?
Not sure this qualifies as a bash script as long as the whole thing is put in a .
You can easily just rename the file and run in on a webpage.
Should try doing it in actual bash, and not use another language hidden in a .sh script.
omg. nevermind.
lol : D
