I have a directory, let's say, "work": ~/work/
This directory has some sub-folders (d1, d2...) in it and files in these sub-folders. I want to make a backup copy in the same folder, so it would be like: ~/backup/work/
However, when I use
cp -r ./work ./backup
the folder "work" is not copied, only its subfoders (so now it's ~/backup/d1 ~/backup/d2...)
Any idea how to make it work? I'm quite new to shell, so I'm missing something :)
