A Git alias to copy a file or directory

.gitconfig

# Usage: git cp [OPTION...] SOURCE DESTINATION
#
# Options:
#
#   In theory, the command accepts all command line options supported by
#   the /bin/cp command.  In reality,  however,  only  few  options  are
#   useful. This includes:
#
#     -R, -r, --recursive
#         Recursively copies a directory.
#
#     -f, --force
#         Removes  an existing destination file  first  if it  cannot be
#         overwritten.
#
#     -i, --interactive
#         Prompts before overwriting existing files or directories.
#
#     -n, --no-clobber
#         Avoids overwriting existing files.
#
#     -v, --verbose
#         Informs the user about what is being done.
#
# Examples:
#
#   git cp en_GB/man1/w2do.1 en_AU/man1/w2do.1
#       Copies the "en_GB/man1/w2do.1" file to "en_AU/man1/w2do.1".
#
#   git cp -R en_GB en_AU
#       Copies all files  and  directories  in  the "en_GB" directory to
#       "en_AU".
