What is the disadvantage of using the cat command to display a very large text file? How can you get around this problem?
What will be an ideal response?
Although some text files can be displayed completely on the terminal screen, you might encounter text files that are too large to be displayed. In this case, the cat command displays the entire file contents in order to the terminal screen and the top of the file is not displayed because there is not enough screen area to do so. Thus, it is useful to display text files in a page-by-page fashion by using either the more or less commands.
