Sometimes you have a set of environment variables in a
.env file. And sometimes you would like to consume them in a shell script. You can do that like this:
export $(cat .env | xargs)
In some special cases you might have the .env file somewhere on the net and would like to include it. Here curl comes in handy:
export $(curl -SsL https://my.coolserver.com/.env | xargs)
This URL also can be a link to some raw file on GitHub or GitLab.
But be careful about what you include from somewhere on the net!
