Grasping the basics of Bash
Just the Beginning
Naturally, there is more to Bash than detailed here. Bash is such a large subject that it takes years to learn its intricacies. In fact, it is so large that few people can claim to know it completely.
However, the points I mention here should serve as a general orientation. If nothing else, they should be enough to show that Bash is a flexible program with countless ways to save you effort – if only you take the time to learn. If you familiarize yourself with these basics, you should know enough to really take advantage of the usefulness of Bash.
