Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I want run a script every 10 minutes I created a file names dyndns em: /etc/cron.d
An I put that line: 0, 10, 20, 30, 40, 50 * * * * root /etc/ppp/ip-up.d/dyndns_update.sh >/dev/null 2>&1 But the script don't run. Why?
If you're sure that the syntax is already correct, first you must at least know if the script runs but just immediately bails out. Add a line similar to this in the beginning of the script. Check if a file is created.
cat /dev/null > /tmp/file
If a file is created, it should be a problem with the script. You can post the script here so that others can also see it if you like.
The cron.d is running the script is running to because when I execute the script in terminal there's no problem. The only problem can be this line 0, 10, 20, 30, 40, 50 * * * * root /etc/ppp/ip-up.d/dyndns_update.sh >/dev/null 2>&1
