🎯 Goal: Learn how to use single quotes in bash scripts to create literal strings that do not interpret special characters.

📋 What You'll Learn

Create a variable with a literal string using single quotes

Create a second variable with a string that includes special characters

Use echo to display the exact content of the variables

💡 Why This Matters

🌍 Real World

Scripts often need to handle file paths or messages with special characters exactly as typed, such as configuration files or user prompts.

💼 Career

Understanding how to use single quotes for literal strings is essential for writing reliable bash scripts in system administration and automation tasks.

1

Create a variable with a literal string using single quotes

Create a variable called message and assign it the exact string 'Hello, $USER!' using single quotes.

Bash Scripting

# Create the variable message with the literal string 'Hello, $USER!'
# Your code here

Need a hint?

Use single quotes around the string to keep it literal.

2

Create a second variable with special characters

Create a variable called path and assign it the exact string 'C:\\Program Files\\MyApp' using single quotes.

Bash Scripting

message='Hello, $USER!'
# Create the variable path with the literal string 'C:\\Program Files\\MyApp'
# Your code here

Need a hint?

Remember to double the backslashes inside single quotes to keep them literal.

3

Display the variables using echo

Use echo to print the variables message and path on separate lines.

Bash Scripting

message='Hello, $USER!'
path='C:\\Program Files\\MyApp'
# Use echo to print message and path on separate lines
# Your code here

Need a hint?

Use double quotes around the variable names in echo to preserve spaces.

4

Run the script and check the output

Run the script and ensure the output exactly matches these two lines:
Hello, $USER!
C:\Program Files\MyApp

Bash Scripting

message='Hello, $USER!'
path='C:\\Program Files\\MyApp'
echo "$message"
echo "$path"
# Run the script and check output

Need a hint?

The output should show the dollar sign and backslashes exactly as typed.
