Write a script ten_dirs.sh that does these tasks: - make a directory ten - make ten subdirectories ten/dir01, ten/dir02,... through ten/dir10. Note the formatting dir01, dir02, etc., rather than dir1, dir2, etc. - in each subdirectory, make four files, file1.txt through file4.txt, such that file1.txt has one line consisting of the digit 1, file2.txt has two lines, each consisting of the digit 2, file3.txt has two lines, each containing the digit 3, and file4.txt has four lines, each containing the digit 4. Note that hard-coded solutions (e.g., writing mkdir dir01; mkdir dir02; ...), will not receive full credit. You should use a loop of some kind or another. Hint: A convenient way to remove the ten directory and all its files is rm -r ten (search the rm manual page for -r to see what it does), so a convenient way to rerun the scrip several times as you develop it is rm -r ten; ten_dirs.sh
