CP(1) General Commands Manual CP(1)
cp - copy
cp file1 file2
cp file ... directory
File1 is copied onto file2. The mode and owner of file2 are preserved
if it already existed; the mode of the source file is used otherwise.
In the second form, one or more files are copied into the directory
with their original file-names.
Cp refuses to copy a file onto itself.
