output is :

zut
echo test
VBB:~ me$

and not

zut
echo test zut
VBB:~ me$

Because echo $test > test2 writes the output to a file named test2.

this set of commands is does what you would expect:

test="zut"; echo $test; test2=$test; echo "echo test " $test2

Addition to first answer you can assign the value in the file a variable.

echo "$var" ; var= more test2

So you can get string after you wrote to file test2
