What command allows you to view the contents of multiple files at once?

The command that allows you to view the contents of multiple files at once is indeed "cat" followed by the names of the files you want to display. The "cat" command stands for "concatenate" and is commonly used in Linux to read and output the contents of files to the standard output, typically the terminal screen. When you provide multiple file names as arguments, "cat" will sequentially read each file and display their contents in the order they are listed. This makes it very effective for quickly viewing the contents of several text files together in one continuous stream.

For example, using "cat file1 file2" will show the contents of "file1" followed by the contents of "file2" all in one output, without needing to open each file individually.

Other commands listed have different functions and do not specifically serve the purpose of viewing multiple files at once. For instance, "view" is a command used to open files in a read-only mode based on the vi text editor, and while it allows you to view a file, it does not handle multiple files in the same manner as "cat". "show" is not a standard command in Linux for viewing files, and "ls" is used to list directory contents
