Linux Shell Scripting Cookbook - Third Edition

How to do it...

Examine the sequence of interactive inputs. From the previous code, we can formulate the steps of the sequence like this:

notes[Return]docx[Return] 

In addition to the preceding steps, type notes, press Return, type docx, and finally press Return to convert into a single string like this:

    "notes\ndocx\n"

The \n character is sent when we press Return. By appending the return (\n) characters, we get the string that is passed to stdin (standard input).

By sending the equivalent string for the characters typed by the user, we can automate passing input to the interactive processes.
