What is Linux Shell?

The shell is the interface between the user and Linux; every command you type at the prompt is interpreted by the shell and passed to the Linux kernel .

The shell is a command-language interpreter with its own built-in shell command collection . In addition, the shell can be called by any other valid Linux utilities and application programs in the system .

Whenever you type a command, it is interpreted by the Linux shell .

For example:

The command of printing current working directory (PWD) is contained within Linux bash .

The copy commands (cp) and the move commands (rm) are two single programs that exist in a directory on the file system .

The shell first checks to see if the command is an internal command, and then checks to see if it is an application, either of Linux's own utilities, such as ls and rm, or of a purchased commercial program, such as xv and ghostview .

Another important feature of the shell is that it is an interpreted programming language that supports most data structures, such as loops, functions, variables, and arrays .

Shell Scripting

A Shell script is a scripting program written for the Shell .

Shell Working Environment

Shell scripting, like Java, C++ programming, requires only a text editor to write code and a script interpreter to interpret execution

Various Linux Shell

Linux has different types of shells, such as:

• Bourne Shel l /bin/s h
• Bourne Again Shel l /bin/bas h
• C Shel l /usr/bin/cs h
• K Shel l /usr/bin/ks h
• Shell for Roo t /sbin/s h

This book talks about Bash (Bourne Again Sell) . Bash is the default Shell on most Linux systems .

The First Shell Scripting

Example 1.1

1. Open the Vi text editor with a vi command .

1. Press i key, enter the Insert Mode .
2. Type the following code in the Vi editor:

# ! /bin/bash echo "Hello World ! "

1. Press the Esc key to quit the Insert Mode .
2. Type :wq study.sh to save the file . The file name is study . sh, the extension name is . sh .
3. Run this Shell program with the following commands:

bash study.sh

Output:

Hello World !

Explanation:

vi is a command to open the Vi editor .

i key is used to enter the Insert Mode in Vi editor .

Insert Mode can be used for writing and editing Shell Scripts .

# ! /bin/bash let Shell system know that using Bash to interpret the scripting .

echo "Hello World ! " shows the content Hello World !

Esc key is used to quit the Insert Mode in Vi editor .

: wq file_name saves the Shell file, and quit from Vi .

bash study . sh executes the Shell file study . sh .

bash myFile.sh executes the Shell file myFile.sh.

Shell Comment

#

# symbol is used for the Shell comments .

Shell interpreter always ignores the Shell comments

Example 1.2

# ! /bin/bash

echo "Hello World ! " # output Hello World!

echo "Hi, Friends ! " # output Hi, Friends!

Output:

Hello World !

Hi, Friends !

Explanation:

# output Hello World ! is a comment of Shell scripting .

# output Hi, Friends ! is a comment of Shell scripting .

Multi-Line Comments

: < comment 1 comment 2 comment 3 ... EOF

: < .

Example 1.3

# ! /bin/bash

echo "Hello World ! "

:<

This is a "Hello World" program .

This is a Shell scripting .

This is a sample of multi-line comment .

......

EOF

echo "This is a sample of multi-line comment . "

Output:

Hello World !

This is a sample of multi-line comment .

Explanation:

:< is used for multi-line comments .

Shell Variables

1. The syntax to define a variable is as follows:

var=value

Note: There must be no Spaces before and after the equal sign !
