Exports a list of env vars to the environment, supporting spaces, newline chars and quotes in the value

export_env_vars.sh

#!/bin/sh

# wraps the env var values in quotes and handles newlines
# It's a more sohisticated version from just doing export $($ENV_VARS)
# and it doesn't break with newline characters, quotes or spaces in the values (note the encoding with sed)

eval "$(
  printf '%s\n' "$ENV_VARS" | while IFS='' read -r line; do
    key=$(printf '%s\n' "$line"| sed 's/"/\\"/g' | cut -d '=' -f 1)
    value=$(printf '%s\n' "$line" | cut -d '=' -f 2- | sed 's/"/\\\"/g')
    printf '%s\n' "export $key=\"$value\""
  done
