// From the top to the bottom:
//
// - A shell line is composed of multiple command lines, first separated by ";" and then chained by "&&" / "||"
// - A command line is composed of multiple commands chained by "|" / "|&"
// - A command is composed of multiple arguments separated by spaces
// - An argument can be a value argument (sent to the underlying program), or a redirection
// - A value argument is a combination of argument segments
