This is the power of Linux and UNIX command lines. There is much more to learn, as there are different shells, and different shell syntaxes available. Also, regular expressions are useful, and there are plenty more utilities available, and if a liking towards the shell is taken, shell scripts can be written to perform a lot of tasks, including backing up directories and more!
