Unix / Linux Print Environment Variables Command

Best/Tutorial

In Unix/Linux, you can print the values of environment variables using the echo command and the syntax $ . Here’s an example to print the value of the PATH environment variable:

echo $PATH

To print the values of all environment variables, you can use the printenv or env command:

printenv

or

env

This will print the values of all environment variables, one per line. You can use the output of this command to see the current values of the environment variables and use that information to make decisions in your shell scripts.
