mkdir: cannot create directory `/foo/dir2': No such file or directory
touch: cannot touch `/foo/dir2/file1': No such file or directory

When I ran it with the -p I received:

mkdir: cannot create directory `/boo': Permission denied
touch: cannot touch `/boo/dir1/file1': No such file or directory
mkdir: cannot create directory `/boo': Permission denied
touch: cannot touch `/boo/dir2/file1': No such file or directory

touch: cannot touch `/doo/doo_file': No such file or directory
mkdir: cannot create directory `/foo': Permission denied
touch: cannot touch `/foo/dir1/file1': No such file or directory
mkdir: cannot create directory `/foo': Permission denied
touch: cannot touch `/foo/dir2/file1': No such file or directory
touch: cannot touch `/foo/foo_file': No such file or directory

Thanks again.

It fails because you are trying to create those in `/' and you are not root.
Remove the `/' in front of directories in the script
