Combining (concatenating) multiple files into a single file
If multiple source files are specified before the path to an existing directory, then files are copied to the directory
Support for text vs. binary data; for text, the command stops when it reaches an end-of-file (EOF) character; for binary, files are copied in their entirety, ignoring EOF

Some shells provide a copy command with a different name. In Unix-based systems, the copy command is cp. In CP/M, the command is PIP. in OpenVOS, the command is copy_file.[25]
