Cron is a system daemon used to execute desired tasks (in the background) at designated times. I am demonstrating most simple form of cronjob in ubuntu.

1. Open terminal and enter the following command:crontab -e
2. Enter following line of code: 34 09 * * * env DISPLAY=:0 gedit
3. Save this settings

Description: Here 34 represents minute, 09 represents hour and *,* and * are for every day, month and weekdays and * represents always. This will open text editor on 9 am and 34 minutes everyday, every month and every weekdays. Change 34 and 09 to your nearest upcomming time. For eg if your current time is 10:20 AM then change 34 to 24. So that you can see result within few minutes. So your modified command will look like this 24 10 * * * env DISPLAY=:0 gedit. Command env DISPLAY=:0 is for displaying gui programs like gedit. You can replace gedit with skype or any programs you like. crontab -e command is for editing the existing cron jobs. To check your existing cron job hit crontab -l in the terminal.

Some times while we wish to run any project on xamp or wamp or lampp we might this error message as:

Access forbidden!

If you think this is a server error, please contact the webmaster.
Error 403
localhost
Mon 24 Oct 2011 07:45:12 PM NPT
Apache/2.2.17 (Unix) DAV/2 mod_ssl/2.2.17 OpenSSL/1.0.0c PHP/5.3.5 mod_apreq2-20090110/2.7.1 mod_perl/2.0.4 Perl/v5.10.1

This is due to the permission problem. By default we don't have permission to access files so we need to change its permission. I have installed my xampp on /opt/lampp/ folder and my project folder name is testproject. To avoid this error i have granted permission as:

sudo chmod -R 0777 /opt/lampp/htdocs/testproject

After running this code on terminal. It works fine.
