Run a job every first Sun of a month
I came across an interesting cron issue recently. The requirement was to run a job every _first_ Sunday at 12:00PM of each month.
After searching across various sites, skimming through cron manpages, I finally found the following one-liner
0 0 1-7 * 0 <user> <job>Can you believe this simple solution? The reasoning is that Sun will be between 1 to 7th of each month. Once a Sun comes, the job will execute between 1st and 7th just once. After that any further Sundays will have a date greater than 7, and thus never execute!
Sometimes, the simplest solution is the most elegant. BTW, I had read about many other complicated solutions, such as having your own logic to determine the day, apple script, bash script solutions. I was about to give up, when I hit the jackpot! 😀

Using Apache’s mod_rewrite on Windows
I recently happened to experiment with Apache’s mod_rewrite, an excellent library to change your machine friendly (or perhaps program friendly?) web urls into user friendly urls.
The steps to make mod_rewrite to work on Windows is-
– Edit httpd.conf for Apache, and uncomment the following line
# LoadModule rewrite_module modules/mod_rewrite.so
-to-
LoadModule rewrite_module modules/mod_rewrite.so– Next, under <Directory “{Your document root}“> change
AllowOverride None
-to-
AllowOverride All– Restart Apache
– Create a sample folder “rewrite” under {Your document root}, with the following files
{Your document root}
rewrite
.htaccess
details.php– What we will attempt now is to have a url like http://localhost/rewrite/details/shantibhushan to be automatically executed as http://localhost/rewrite/details.php?user=shantibhushan
– Edit your .htaccess file as follows
<IfModule rewrite_module>
RewriteEngine on
RewriteBase /rewrite/
RewriteRule ^details/(.+)$ details.php?user=$1 [L]
</IfModule>– The RewriteRule is the actual line where we specify what url is to be mapped to which actual url. ^details/(.+)$ takes a user friendly url /details/shantibhushan and extracts “shantibhushan” as $1. It then replaces $1 into details.php?user=$1 resulting in details.php?user=shantibhushan as the actual url.
– Edit details.php as follows
<?php
$user= $_REQUEST[‘user’];
print(“<h1>$user</h1>”);
?>
– The above sample simply takes “user” from details.php?user={user} and shows it back.– Done! Try accessing http://localhost/rewrite/details/shantibhushan and you should see details.php getting called with parameter as “shantibhushan”
TODO
– Simply accessing details/ results in error, and rewrite rule doesn’t assume such a case. It can be handled by RewriteCond
– First I wanted to have details:shantibhushan as the url, but this has a bug on Windows not allows : in path. It seems to work fine on non-Windows.
– The example assumes Apache is running on port 80 on your machine.
