Getting Started
 Introduction to Kernel.
 Linux Shell & Types & Usage.
 What is Shell Script.
 Uses of Shell Scripting
 Getting help in Linux

Introduction to Kernel
 Kernel is heart of Linux O/S.
 It manages resources of Linux O/S.
o I/O management
o Process management
o Device management
o File management
o Memory management

Linux Shell
Computer understand the language of 0's and 1's called binary language.
Shell accepts your instruction or commands in English and translates it into
computers native binary language.

5. kerneltraining.com/shell-scripting
Types of Linux Shells
 Shell is not part of system kernel, but uses the system kernel to execute
programs, create files etc.
 Several shell available with Linux.
o BASH – Bourne-Again Shell.
o CSH – C Shell.
o KSH – Korn Shell.
o TCSH – Advanced Version of C Shell.

Shell Script
 Shell Script is series of command written in plain text file.
 An advanced shell script will be mentioned with She-Bang to load the type of
interpreter to execute the script.
 If no interpreter is mentioned then the current shell will be used by default.

7. kerneltraining.com/shell-scripting
Uses of Shell Script
Combine lengthy and repetitive sequences of commands into a single, simple
command.
Generalize a sequence of operations on one set of data, into a procedure that
can be applied to any similar set of data.
Create new commands using combinations of utilities in ways the original
authors never thought of.
Simple shell scripts might be written as shell aliases, but the script can be
made available to all users and all processes. Shell aliases apply only to the
current shell.
Create customized datasets on the fly, and call applications.

Getting Help in UNIX
To get the help in Linux Command line you can use the following commands
followed by the command name to get displayed the information of the
command in detail.
 Help
 Man
 Info
