Variable assignment (no spaces around =) in Bash Scripting - Mini Project: Build & Apply

Variable assignment (no spaces around =)

📖 Scenario: You are writing a simple bash script to store and display your favorite fruit.

🎯 Goal: Create a variable to hold the name of your favorite fruit and then print it.

📋 What You'll Learn

Create a variable called fruit with the value Apple using no spaces around the = sign.

Create a variable called count with the value 3 using no spaces around the = sign.

Use a variable called total to store the sum of count and 2.

Print the value of fruit and total.

💡 Why This Matters

🌍 Real World

Bash scripts often use variables to store data like file names, counts, or user input. Correct variable assignment is essential for scripts to work.

💼 Career

Many IT and DevOps jobs require writing bash scripts for automation. Knowing how to assign and use variables correctly is a basic but crucial skill.

1

Create the fruit variable

Create a variable called fruit and assign it the value Apple with no spaces around the = sign.

Bash Scripting

# Create the variable fruit with value Apple
# Your code here

Need a hint?

Remember, in bash, do not put spaces around the = sign when assigning variables.

2

Create the count variable

Create a variable called count and assign it the value 3 with no spaces around the = sign.

Bash Scripting

fruit=Apple
# Create the variable count with value 3
# Your code here

Need a hint?

Use the same style as the fruit variable assignment.

3

Calculate the total variable

Create a variable called total that stores the sum of count and 2. Use $(( )) for arithmetic and no spaces around the = sign.

Bash Scripting

fruit=Apple
count=3
# Calculate total as count plus 2
# Your code here

Need a hint?

Use total=$((count + 2)) to do arithmetic in bash.

4

Print the variables

Print the value of fruit and total using echo. Use $fruit and $total to access the variables.

Bash Scripting

fruit=Apple
count=3
total=$((count + 2))
# Print fruit and total
# Your code here

Need a hint?

Use echo $fruit and echo $total to print the values.
