Question: 1 / 400

What command would you use to display the contents of a text file?

cat

The command used to display the contents of a text file is "cat." This command stands for "concatenate" and is commonly used in Unix/Linux environments to read the contents of one or more files and display them to the standard output (usually the terminal).

When you use "cat filename," it reads the specified file and outputs its contents directly in the terminal window. This makes it a simple and effective way to view text file contents quickly. The beauty of "cat" is its ability to handle multiple files in a single command too, which is useful when you want to see the combined contents of several files at once.

The other choices do not represent standard commands in Unix/Linux for displaying file contents. "show" and "list" do not exist as commands in this context, and "read" is typically associated with command shells or scripts for reading input but does not display file contents directly.
