On my CentOS machine, I need to create a main directory inside which I will have a few sub directories and, inside them, some subsubdirectories.
Something like:
main_directory->sub1,sub2,sb3.. sub1->subsub1,subsub2,subsub3.. sub2->subsub1,subsub2,subsub3.. sub3->subsub1,subsub2,subsub3..
I want to create this kind of directory structure using a loop and using mkdir inside the loop. Also, I want the user to input all these directories and sub directories and sub sub directory names. How can I do this?

It is not limited to a fixed number of dirs, so if you want to create 2, 3 or pass your entire life creating directories and sub-directories, until causing a explosion, here is the script:
#!/bin/bash
enter_recursive(){
while true; do
echo "Please enter the name of the directory you want to create inside $PWD or type _up to exit the directory"
read dir
[ "$dir" = "_up" ] && return
mkdir "$dir"
echo -n "Do you want to create subdirectories in $PWD/${dir}? (y/n)"
read -n1 yn
echo
if [ "$yn" == "y" ]; then
cd "$dir"
enter_recursive
cd ..
fi
done
}
enter_recursive
