Mastering Linux Shell Scripting - Second Edition

Hello Dolly!

It is possible that we might need a little more substance in the script than a simple fixed message. Static message content does have its place, but we can make this script much more useful by building in some flexibility.

In this chapter, we will look at the positional parameters or arguments that we can supply to the script and in the next chapter, we will see how we can make the script interactive and also prompt the user for input at runtime.
