    Which command is true to create a file?

    • Cat >> file name

    • Cat < file name

    • Cat < file name

    • Cat > file name

    Correct Answer
    A. Cat > file name
    Explanation
    The correct answer is "cat > file name". This command is used to create a file in Unix-like operating systems. The ">" symbol redirects the output of the "cat" command to a file with the specified name. This means that if the file already exists, it will be overwritten, and if it doesn't exist, a new file will be created.

    • Tail 15 dog cat horse

    • Tail -15 /dog cat horse

    • Tail -15 dog cat horse

    • Tail -15 dog, cat, horse

    Correct Answer
    A. Tail -15 dog cat horse
    Explanation
    The correct answer is "tail -15 dog cat horse". The "tail" command is used to display the last part of a file. The "-15" flag specifies that we want to see the last 15 lines. By listing the file names "dog", "cat", and "horse" after the command, we are telling the command to display the last 15 lines of each of these files.

    • The contents of the file dog and any error messages.

    • Nothing as all output is saved to the file cat.

    Correct Answer
    A. Nothing as all output is saved to the file cat.
    Explanation
    When the command "cat dog & > cat" is executed, it redirects the output of the command "cat dog" to a file named "cat" using the ">" symbol. The "&" symbol is used to run the command in the background. As a result, no output will be displayed on the screen, and all the output will be saved to the file named "cat". Therefore, the correct answer is "Nothing as all output is saved to the file cat."
