Shell Scripting Logic and Calculation Quiz

Shell Scripting Basics

• The echo command is used to output text to the screen.
• The read command is used to get user input, and the input is stored in a variable.

Calculating Circumference

• The formula for calculating the circumference of a circle is 2 * 3.14 * $r, where $r is the radius of the circle.
• The unit of measurement for the circumference is not specified, but it is likely to be in meters or centimeters.

Conditional Statements in Shell Scripting

• A conditional statement is used to generate a true or false value based on a particular condition.
• The conditional statement has two blocks: the first block displays the true value, and the second block displays the false value.
• The if keyword is used to start a conditional statement, and the fi keyword is used to close it.
• The else keyword is used to specify the alternative action if the condition is false.
• The syntax for a conditional statement is: if [condition] then statement else statement fi
• The fi keyword is compulsory to close a conditional statement.

Example of Conditional Statement

• The example given is: if [condition] then statement else statement fi
• This syntax is divided into two blocks: then and else
• The then block is executed if the condition is true, and the else block is executed if the condition is false.
