        -R,-r   Copies directories recursively

# cp nonexistent foo
cp: nonexistent: No such file or directory
# echo $?
1                          # Correct.
# cp verybigfile foo
cp: Write Error: No space left on device
# echo $?
0                          # Bug. Should be non-zero according to POSIX.
