I want to delete directory 982899. It is located under directory big.
When I first try to delete 982899, it shows many lines of messages like this:
rm: cannot remove `982899/.../...v': Permission denied
So I use chmod 777 . to make directory big be able to change everything.
However, after it, rm -rf 982899 still shows the same messages:
rm: cannot remove `982899/.../...v': Permission denied
I even executed chmod 777 982899, but nothing changed!
Why ? What should I do to delete directory 982899?
