You are required to build a shell scr ipt that does text file processing. The requirements

of the text file processing are:



A. Make sure there is ONLY one single blank space after a full stop (.) and the character

that comes right after it.

B. Same behavior as in [A] for commas (,), semicolons ( ), an exclamation mark (!) and

question marks (?).

C. Remove extra blank spaces between words.

D. Capitalize every word that comes right after a full stop, an exclamation mark, a

question mark or a semicolon. Capitalize means make the first character of a word

capital letter.

E. Make lower case all the remaining letters that do not satisfy condition [D].

F. Insert a blank line between paragraphs.

G. Insert a dot at the end of each paragraph if there are no dots.
