Hi,

I need to know what is the rationale behind this behavior ?

> cp aa bb
aa does not exist and neither does bb. No warning is thrown on performing
this operation.

However,
if I do

> cp dd cc
where cc is a non empty file, then a warning is thrown about the source file
being empty| invalid.
This is the warning thrown.

cp: cannot stat `dd': No such file or directory


Can I please know the rationale behind this behavior?



Thanks
