I don't know how to copy a directory.
In exercise 5 cp Ⅰ, it is said that I can use the
cp command to copy files or directory, but i cannot see any advice on copying a directory. So i try to copy a directory in my own computer.
There is a directory called dir_0 in my root directory and i wanted to make a copy of it. so i typed this command
cp dir_0 dir_1 in my terminal. As a result, i encountered an information saying cp: omitting directory 'dir_0', as shown in the following snapshot. What's wrong? Any suggestion? Thank you
