To "disable all lines" you would simple comment out the lines (or blank them)
To blank the file, simple:
To comment out all lines:
sed -e 's/^/#/g' file > tmp && mv tmp file
To add your own text to something you most likely want "echo" along with "read":
echo -n "What is your hostname? "
echo "Hostname: $ANSWER" >> file
That's the very basics. For anything more complicated you'll need to give more context to work with.
