Environment Variables

For environment variables, when you don’t use them often, it’s not always easy to remember the commands.

To display your PATH:

1

echo $PATH

To display all environment variables:

1

env

To add something to your PATH:

1

PATH=$PATH:/path/to/add

To add a new environment variable:

1
2

MYVAR=/toto
export $MYVAR

Check with the env command and it works! :-)
