Which command would you use to display the contents of a text file in the terminal?

• A. cat
• B. echo
• C. print
• D. show

Answer: (A)

Using the command `cat` is the most straightforward way to display the contents of a text file directly in the terminal. The `cat` command, short for "concatenate," reads the specified file(s) and outputs their contents to the standard output, which is typically your terminal. This command is particularly useful for quickly viewing the content of files without any additional formatting. In contrast, the other options do not serve this primary function effectively. For instance, `echo` is designed to display a line of text or variables provided to it, but it's not used to read the contents of a file. The command `print` does not exist in standard Linux command-line interface as a command to read files, and similarly, `show` is not a recognition command for this purpose in Linux. Thus, `cat` emerges as the appropriate choice for displaying file contents.
