(Bash) How to set a variable with text from a file? [SOLVED]

I'm having a little problem.
I have textfile with a single line of text. What I want to do is set a variable with that line of text. How do I go about doing that?

A simple var="text" wont work in this case, since the text in the file changes with another script of mine.

Thanks in advance.

Or var=$( cat file ), if you like.

if you have a file with more than one line but you only want the first line you could use 'head'

VAR=`head -n 1 file`
