The first program (rdr) reads the input data and pipes it to the next
program (sqh) unchanged except that a space character has replaced the
new line character at the end of each line. The sqh program pipes the
data to the third program (ptr) unchanged except that
all double asterisks are replaced by the ^ character. The ptr
program takes the characters and prints them as 10 character lines,
that is, 10 characters plus the new line character.
