The command used to copy files in Linux is "cp." This command allows users to create duplicates of files or directories, which can be specified by providing the source file and the destination where the copy will be placed. The syntax is straightforward, with the basic form being `cp [source] [destination]`. Additionally, the "cp" command supports various options to modify its behavior, such as `-r` for copying directories recursively or `-i` for prompting before overwriting an existing file.

In contrast, "copy" is a command commonly used in DOS/Windows environments, while "xcopy" is a more advanced copying command available in the Windows ecosystem, enhancing functionality beyond the basic "copy" command. The "mv" command, on the other hand, is utilized for moving files or renaming them, rather than creating copies.
