Input and output handling is to ensure that data passed between computing systems do not yield unexpected behaviour on the systems, i.e. There a few methods which can make data safe for handling, with different level of security and applicability: Validating data is to ensure that data is safe prior to use.

The most secure way from a usability point of view.

read var1 Let's look at a simple example: You are able to alter the behaviour of read with a variety of command line options.

(See the man page for read to see all of them.) Two commonly used options however are -p which allows you to specify a prompt and -s which makes the input silent.

In this example there are 3 specific files (each color block is a file with 6 lines), but the next time there may only be two.

If each line in the file is a match to description then the file is verified/good, but if it does not then the file is not.

There are a number of examples that you should examine for detailed usage.

Getting started with Note that, while this structure is similar to that used by prompt 0.1.x, that the object properties use the same names as in JSON-Schema.
