Using the very simple LaTeX document below, named test.tex:






When running latex test.tex, I am getting the error reported as follows in the log file:

Welcome to TeX.sx! What should $ cat test.tex be? Commenting that line out, it works. But it seems your distribution hasn't been updated in a long time. – Qrrbrbirlbel Oct 21 '12 at 19:33
Seems like you are using an outdated LaTeX system, Update your system and your code will work (commenting out the $ cat test.tex line) – Gonzalo Medina Oct 21 '12 at 19:35
The $ cat test.tex is just the UNIX command line for printing the file to the screen. My system is running Fedora 16 and is completely up-to-date. I'll look into finding more up-to-date LaTeX packages. – Quincy Bowers Oct 21 '12 at 19:48
@QuincyBowers I've removed the shell commands that, as you see, can be confusing for people not acquainted with the shell; who knows about the shell is sometimes surprised that other people have never heard about it. By the way, Qrrbrbirlbel was surely referring to the TeX distribution rather than the operating system. From the log file it can be seen that scrartcl is from 2006, while in the most recent TeX distributions it is dated 29 July 2012. – egreg Oct 21 '12 at 19:56
I just assumed that if Fedora said I was up to date than I should be reasonably up-to-date. Apparently Fedora has an embarrassingly old version of LaTeX though. I am updating it now. – Quincy Bowers Oct 21 '12 at 20:03
