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:

  echo $PATH
  

To display all environment variables:

  env
  

To add something to your PATH:

  PATH=$PATH:/path/to/add
  

To add a new environment variable:

  MYVAR=/toto
export $MYVAR
  

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