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

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

cp

CP(1)							      General Commands Manual							     CP(1)

NAME

       cp, cpdir - file copy

SYNOPSIS

       cp [-pifsmrRvx] file1 file2
       cp [-pifsrRvx] file ... directory
       cpdir [-ifvx] file1 file2

OPTIONS

       -p     Preserve full mode, uid, gid and times

       -i     Ask before removing existing file

       -f     Forced remove existing file

       -s     Make similar, copy some attributes

       -m     Merge trees, disable the into-a-directory trick

       -r     Copy directory trees with link structure, etc. intact

       -R     Copy directory trees and treat special files as ordinary

       -v     Display what cp is doing

       -x     Do not cross device boundaries

EXAMPLES

       cp oldfile newfile  # Copy oldfile to newfile

       cp -R dir1 dir2	   # Copy a directory tree

DESCRIPTION

       Cp  copies one file to another, or copies one or more files to a directory.  Special files are normally opened and read, unless -r is used.
       -r also copies the link structure, something -R doesn't care about.  The -s option differs from -p that it only copies  the  times  if  the
       target file already exists.  A normal copy only copies the mode of the file, with the file creation mask applied.  Set-uid bits are cleared
       if the owner cannot be set.  (The -s flag does not patronize you by clearing bits.  Alas -s and -r are nonstandard.)

       Cpdir is a convenient synonym for cp -psmr to make a precise copy of a directory tree.
