    en.wikipedia.org/wiki/Filename_extension

    The use of a filename extension in a command name appears occasionally, usually as a side effect of the command having been implemented as a script, e.g., for the Bourne shell or for Python, and the interpreter name being suffixed to the command name, a practice common on systems that rely on associations between filename extension and ...

    A delimited text file is a text file used to store data, in which each line represents a single book, company, or other thing, and each line has fields separated by the delimiter.
