A file can contain any type of data. For example, it could be plain text, a picture, a video or many more. The file command tries to guess what type of data is in the file. It’s not perfect because it’s not always possible to tell (e.g. when a file called picture.jpg is empty). Plain text files can be viewed on the command line with cat and less.
