Which command is used to display the contents of a text file in the terminal?

The command that is used to display the contents of a text file in the terminal is "cat." This command is widely utilized in Unix-like operating systems and stands for "concatenate." Its primary function is to read files sequentially and output their contents to standard output, which is usually the terminal screen.

When you execute the command followed by the filename, it reads the entire file and displays its content line by line until the end of the file is reached. One of the advantages of using "cat" is its ability to quickly show the contents of small files. Additionally, "cat" can be used for other purposes, such as combining multiple files into one by listing more than one filename, or even creating new files with the output redirection.

The other options serve different purposes: "echo" is used to display a line of text or a variable's value to the terminal, "show" is not a standard command for displaying file contents, and "more" is used for paging through the content of the file one screen at a time. While "more" can display the contents of a file as well, it doesn't do so in the same straightforward manner as "cat" and is designed primarily to manage larger files that don't fit on
