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

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

Answer: (B)

The command that is commonly used to view the contents of a file in Linux is "cat." This command reads the file specified as an argument and outputs its content to the standard output, typically the terminal. It is particularly useful for displaying short files directly in the terminal. While there are other commands that can be used to view files, "cat" is widely recognized for its simplicity and directness. It does not require any additional options for basic file display tasks, making it a fundamental command for file handling in Linux. The output can also be piped or redirected to other commands or files, offering flexibility in how the file content can be used. Other commands like "view" or similar might serve to open files in paged formats or other specific contexts, but "cat" is the foundational tool for merely displaying file content. Therefore, understanding "cat" is key to interacting with files in a Linux environment.
