If you just want to quickly copy the text of a file to the clipboard while in terminal you can just use:

cat [filename]

That will display the full text of the file to the terminal and you can just highlight the text and copy.

One case where this can be useful is as a quick and simple way to copy text to the clipboard of your laptop when you ssh into a remote server. If contents of the file are larger than a screen it can be difficult to scroll and copy the text you want to copy without using the cat command.
