Which Linux command is used to view the contents of a file?

• A. cat
• B. view
• C. show
• D. open

Answer: (A)

The command used to view the contents of a file in Linux is "cat." This command is designed to concatenate and display the content of files sequentially. When you enter "cat" followed by the filename, it reads the file and outputs its contents to the terminal. This makes it a straightforward and efficient way to quickly inspect the content of a file, especially for small text files. In contrast, while "view" is often used in conjunction with text editors like "vi" to view the contents of a file, it is not a standalone command for simply displaying file content in the same manner as "cat." The commands "show" and "open" do not correspond to standard Linux commands for viewing files. "show" is more often associated with network configuration commands and "open" is commonly found in other operating systems like macOS to open files or applications, but not in the context of Linux for viewing file contents directly.
