The canonical way is to use "tail -n 1". Joachim -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Joachim Schrod Email: jschrod@acm.org Roedermark, Germany -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That was mentioned. Plus the actual symptom came from there not being an end-of-line / newline on the final line of the file and the way that lack interacts with BASH's read built-in, not actually the absence of a blank last line. Thus the use of tail, which does not add an final newline when one is missing, would not itself fix the original script misbehavior.
