Which syntax redirects both standard output and standard error to a file, leaving no output on screen?

• A. Command > File
• B. Command 2> File
• C. Command &> File
• D. Command > File 2>&1

Answer: (C)

In Bash, both standard output (1) and standard error (2) can be sent to the same file with a single redirection operator: &> File. This makes sure nothing is shown on the screen because both streams are redirected to that file. The reason this is the best choice here is that it’s a concise, unambiguous way to combine both outputs at once, without worrying about the order of multiple redirections. Other forms either redirect only one stream (stdout or stderr) or require a two-step sequence like > File 2>&1, which works but is more verbose and depends on the correct ordering. Note that &> is a Bash-specific shorthand and isn’t portable to every shell, but in Bash it cleanly achieves the goal.
