Can echo display variable values?

Yes, the echo command can display variable values in Linux. You can use it to print the value of a variable by prefixing the variable name with a dollar sign ($).

Example:

MY_VARIABLE="Hello LabEx"
echo $MY_VARIABLE

When you run this, it will output:

Hello LabEx

This is useful for displaying the contents of variables in scripts or during command-line operations. If you have more questions or need further clarification, feel free to ask!
