You are probably typing it as:

echo "HI!" >> test.txt

! is a special character in bash (Linux) and needs to be escaped like so:

echo "HI\!" >> test.txt

Hope this helps.

This is not what he is typing. There is no ! in his command. – ianaya89 Jan 03 '15 at 05:21
the command typed in this question might not be the whole code. Sometimes we suspect code in some other location when it actually happens else where. – Ganesh Kamath - 'Code Frenzy' Jan 03 '15 at 05:22
You are right, but in this case you are assuming that his entering "HI!" and clearly this is not what he is typing. – ianaya89 Jan 03 '15 at 05:24
he might update his question any time soon, lets wait and watch :) – Ganesh Kamath - 'Code Frenzy' Jan 03 '15 at 05:25

You have a syntax error in your command, You need to add the '>>' between your text and your name file and also try removing the quotes:

echo HI >> test.txt
