Load environment variables from dotenv / .env file in Bash

load_dotenv.sh

# The initial version
if [ ! -f .env ]
then
  export $(cat .env | xargs)
fi

# My favorite from the comments. Thanks @richarddewit & others!
set -a && source .env && set +a

@borisdiakur Great but if the .env has comments MY_VAR=some value with spaces # bad

just use

@nikelborm sometimes, you just go to work with what there is..

there's a simple trick for bash users:

readarray -t env < <(grep -v '^#' .env)
export "${env[@]}"

if having the env only in a child process is alright:

grep -v '^#' .env | xargs -od '\n' sh
