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.

do you think this would have the desired effect?

sudo cat >> /etc/apt/apt.conf << eof

Acquire::Queue-Mode "host";

eof

sudo cat >> /etc/sysctl.conf << eof

# Reduce the swap tendency

vm.swappiness = 10

eof

sudo cat >> /etc/apache2/apache2.conf << eof

Include /etc/phpmyadmin/apache.conf

eof

sudo cat >> /etc/fstab << eof

/media/bmike1/entertainment/Pictures /home/bmike1/Pictures none bind 0 0

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?
