The question does not have to be directly related to Linux and any language is fair game.

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.

Using Shell Script, how can i check whether apache is installed in my system, if yes how could i retrive the version no., httpd.conf file path, apachectl file path and httpd file path.
httpd should be on the filepath, so "httpd --version" will return the version number, and the exit status of that command (echo $?) should be 0 if it is installed, > 0 otherwise.
I would rather use a list of usual path for httpd and if the user installed it in an unusual directory, the
script may pause after the search fails and ask the user where httpd is eg :
Code:
#!/bin/bash
KNOWN_PATH="/usr/sbin /sbin /opt/apache2/bin /usr/local/sbin"
HTTPD_DIR=
for path in $KNOWN_PATH; do
echo "trying $path/httpd..."
if `ls $path/httpd > /dev/null 2>&1`; then
HTTPD_DIR=$path
break
fi
done
if [ -z $HTTPD_DIR ]; then
echo "httpd path not found, please enter the path to directory where httpd is"
echo -n "httpd path : "
read HTTPD_DIR
fi
HTTPD="$HTTPD_DIR/httpd"
if [ ! -x $HTTPD ]; then
echo "httpd could not be found, exiting..."
exit 1
fi
$HTTPD -V
