What Others Think

It might be better to have sed -n '5{p;q}' file so you do not read the rest of a possibly long file.

I suggest following - awk 'NR == 3' This will also do the same job :-). But its shorter...

I searched for "print a line number" and didn't find this. But it did show up when I was writing the command.
