Load a .env file into your current shell. Handy when you need to skirt Foreman.

loadenv.sh

function loadenv() {
  env=${1:-.env}
  echo Loading $env
  file=`mktemp -t tmp`
  if [ -f $env ]; then
    cat $env | while read line; do
      echo export $line >> $file
    done
    source $file
  else
    echo No file $env
  fi
}

You could probably do this without a tmpfile, like so:

if [[ -s "$env" ]]; then
  while read line; do
    eval export "$line"
  done < "$env"
fi

The -s test also makes sure it's readable. I've also really enjoyed direnv for this sort of thing.
