Earlier when we covered the shell (bash), we said it had a
programming language built in. In fact, you can write programs, or
shell scripts, to accomplish tasks that a single
command cannot. Like any good programming language, the shell has
variables, conditionals (if-then-else), loops, input and output, and
more. Entire books have been written on shell scripting, so we’ll be
covering the bare minimum to get you started. For full documentation,
run info bash, search the Web, or
pick up a more in-depth O’Reilly book.
