Which command is used to copy files in Linux?

The command used to copy files in Linux is "cp." This command is specifically designed for this purpose and has various options that allow users to customize how files are copied. For instance, the cp command can copy files to a new location, preserve file attributes, and even copy directories recursively.

In contrast, other terms like "move," "copy," and "duplicate" do not represent valid commands for copying files in Linux. The "move" command is used for moving files from one location to another and not for copying. The terms "copy" and "duplicate" may be familiar in other operating systems or contexts, but they are not commands recognized by Linux systems. Thus, "cp" is the precise command that fulfills the requirement of copying files efficiently.
