This might be helpful:
export $(cat .env | xargs) && rails c
Reason why I use this is if I want to test .env stuff in my rails console.
gabrielf came up with a good way to keep the variables local. This solves the potential problem when going from project to project.
env $(cat .env | xargs) rails
I've tested this with bash 3.2.51(1)-release
Update:
To ignore lines that start with #, use this (thanks to Pete's comment):
export $(grep -v '^#' .env | xargs)
And if you want to unset all of the variables defined in the file, use this:
unset $(grep -v '^#' .env | sed -E 's/(.*)=.*/\1/' | xargs)
Update:
To also handle values with spaces, use:
export $(grep -v '^#' .env | xargs -d '\n')
on GNU systems -- or:
export $(grep -v '^#' .env | xargs -0)
on BSD systems.
