You sux, sed solution is faster and shorter: sed -n ${num}p filename

Hi drizzt! :) The following solution is even more efficient, because it stops reading the file as soon as the desired line is found: sed -n '${num}p;${num}q' filename or: sed -n '${num}{p\nq\n}' filename (where \n are literal newlines) Without the additional q command, sed would always read through the entire file.

@drizzzz...: you are right, the sed version is slightly faster, but how come its shorter? :-P
