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.

Great - what have you tried so far and what problems are you having? No one on this forum is going to do your homework for you, but we may be able to help if you give it an honest effort and run into trouble. One thing to note, the *nix path separator is a forward slash, not a backslash as in DOS, so it's not \bin and \sbin but rather /bin and /sbin.
i am completely new to linux C programming and i m searching how can i start , just found this forum and registered here . maybe someone will help me getting starts . and sorry for the slash as you guys can understand how it feels when you dont have a clue about the thing you will have to work with .
Have you read through the rules for the forums? This is one of the points:
Do not post homework assignments verbatim. We're happy to assist if you have specific questions or have hit a stumbling point, however. Let us know what you've already tried and what references you have used (including class notes, books, and searches) and we'll do our best to help. Keep in mind that your instructor might also be an LQ member.
Usually a "real" Unix shell like bash would use stat(2) or one of its variants to check and see if a file exists somewhere in its $PATH.
To the OP - if this is homework you must be taking a class. Did your lectures not cover what you need to know to complete the assignment? If not, maybe you should seek clarification from your professor...
