Is there a particular reason you are trying to create and edit a file
without using and editor?
If you have a typo, or if there is something in the that your new entry
might conflict with you may not know.
Doing this as a super user (root / sudo) seems to me to be asking for
trouble.
Of course it depends on what you are trying to do.
If you are modifying configuration files in particular I see possibility
of unrecoverable excitement.
The apache configuration file has a lot of the settings already in there
and often you just need to uncomment them to activate the option. Of
course you would be working on it only after making a backup copy of the
file.
When you have finished creating a file from the command line you would
use Control D to end the edit mode.
Typing eof will just put the characters eof into the file.

eof
would the single line appendages just need the blank line?

Okay now, I learned just today how >> works and I want to update
all of my reinstall scripts so all I need to do is copy-n-paste
into a terminal and everything will be done. Learned when I was
doing Linux from scratch that to create a file of multiple lines
without starting an editor you do:
*cat > filename << "EOF"
*contents
*of*
*file*
*EOF*
Oh.... I think I get it. just turn the '>' into '>>'
am I correct?
