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;
}
?>

/ 8. januar, 2010Why 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.

#!/bin/bash
quotefile=»${0%/*}/Quotes»
funny=1
if [ "$1" == "gimmemore" ]; then
ping -c 1 bash.org &> /dev/null
[ $? == "0" ] && elinks -dump http://bash.org/?random$funny | sed -n ‘/^.*ModApp.*_____$/,/^.*Home.*Latest.*$/{/^.*ModApp.*_____$/d;p;}’>$quotefile
exit 0
fi
quote=$[$RANDOM%$[$(sed -n '/^.*]#.*$/p’ «$quotefile» | wc -l)-2]+1]
quote=$(bash -c «cat -n «$quotefile» | sed -n ‘/^.*]#.*$/p’ | sed -n «${quote}p» | sed ‘s/^ *([0-9]+).*$/1/g’»)
sed -n «$quote,/^.*]#.*$/{$quoted;/^.*]#.*$/d;p}» $quotefile

/ 26. mars, 2010Haha, that’s awesome! :)
oc
/ 5. april, 2010Or even;
#!/bin/bash
curl «http://bash.org/?random1″ 2>/dev/null | ack -1o ‘(.*)’ –output=’$1′ | sed «s/>/>/g» | sed «s/</</g"
requires curl (curl.haxx.se) and ack (betterthangrep.com) — two excellent commandline tools :)
oc
/ 5. april, 2010Umm. The two last sed’s should be & gt ; and & lt ; (w/o spaces – got escaped).

/ 21. april, 2010No, thanks, I prefer my programs readable and maintable. :p I’m sure you could do it in Brainfuck too if you wanted to. ;)
