Bash Magic

Loop to perform a command multiple times

for i in {1..20}; do php artisan test --filter ReflectionMethodHelperTest; done;

Command to read values from .env file into memory as key-value pairs to reference in a later command

export $(grep -v '^#' .env | xargs)

Use these values in an example command (for connecting to MySQL here)

mysql -h "$DB_HOST" -P "$DB_PORT" -u "$DB_USERNAME" -p"$DB_PASSWORD" -D "$DB_DATABASE" -p

Combined commands into a one-liner

export $(grep -v '^#' .env | xargs) && mysql -h "$DB_HOST" -P "$DB_PORT" -u "$DB_USERNAME" -p"$DB_PASSWORD" -D "$DB_DATABASE" -p
