How can we view the value of a variable in Linux?

To view the value of a variable in Linux, you can use the echo command with a $ prefix before the variable name. Here’s how you can do it:

1. First, create a variable (if you haven't already):

   my_var="Hello, Linux"
   

2. Then, use the echo command to display the value of the variable:

   echo $my_var
   

This will output:

Hello, Linux

Alternatively, you can also use the printenv command if the variable is an environment variable:

printenv VARIABLE_NAME

Replace VARIABLE_NAME with the name of the environment variable you want to check.
