append with eof

[koder]

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.
