Read from text file misses first line

Hi!

I need to read in the first line from a text file (which will only ever have one line in it), so I tried this....

while read line
do
echo $line
done < $file

But this wasn't returning anything. So I tired a different file, which had multiple lines of text in it, and it returned each line apart from the first! Smilie

How do I just read out the first line?

Thanks in advance...
