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.

Hi as part of an assessment I have been asked to create a bash shell script but im RUBBISH at scripting!
I need to create a script that will kill processes of a given name using the commands (among others possibly) pidof, ps -ef and awk. Any help would be greatly appreciated!
Similar questions are asked here often. The standard answer is "We are not going to write your script for you, but will be glad to HELP. Post what you've written so far".
If you want hints, read the man pages on the commands you listed, along with the kill and killall commands. There are also THOUSANDS of bash scripting tutorials you can easily find with Google...have you looked at any of them?
Ok...so your goal is to KILL the process(s), right?? Wouldn't it make sense then to actually put a "kill" statement in there? Right now, all you're doing is printing out the first field. Which isn't the PID. Think about what you're trying to do, and walk through it one step at a time:
Get the process name from the user in the $1. You're doing that now (I'd suggest an exit if the user doesn't provide a process name)
Look through the running processes to see what matches (hint: look at the "-i" option in grep)
Get the PID number for them. It's NOT the first field.
You may have multiple processes that match a name, so you'll need to loop through (hint: look at a "for" loop) and kill them all
