Note: cp – copy files and directories
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.
Cp has three principal modes of operation. These modes are inferred from the type and count of arguments
presented to the program upon invocation.
* When the program has two arguments of path names to files, the program copies the contents of the first file
to the second file, creating the second file if necessary.
* When the program has one or more arguments of path names of files and following those an argument of a
path to a directory, then the program copies each source file to the destination directory, creating any files not
already existing.
* When the program’s arguments are the path names to two directories, cp copies all files in the source
directory to the destination directory, creating any files or directories needed. This mode of operation requires
an additional option flag, typically r, to indicate the recursive copying of directories. If the destination directory
already exists, the source is copied into the destination, while a new directory is created if the destination does
not exist.
