Deleting/Removing sentence from .txt
Hi,

now i need to remove the entires i inserted into my .txt file.

Code:
    echo -n "Title: "
    read Title
    echo -n "Author: "
    read Author
    if grep -q "$Title: $Author" "BookDB.txt"; then
	sed '$Title: $Author' BookDB.txt
	echo "Book Title '$Title' removed successfully!"		
    else
	echo "Error! Book does not exists!"
    fi

my sed command doesnt seems to work. my BookDB.txt contains the Title, Author and price of the book. Required to delete the whole sentence just by the input of Title and Author.

For E.g

ABC:John:5

where ABC = Title, John = Author, 5 = Price.

Much help would be appreciated =)
