    Why do you think a latex.tex should exist? latex.ltx is the right file which contains the latex code. Commented Apr 5, 2011 at 14:05

    Why do you need to find such a file?

  • I think latex.ltx was once called latex.tex; in LaTeX2 or maybe even earlier. I remember to have read at least one mentioning of it. Commented Apr 5, 2011 at 15:19

    @araz: \chapter* is not a command. It's a \chapter with a * afterwards. The definition of \chapter checks (using \secdef) if a * follows and calls \@chapter or \@schapter depending on the result. This is an example of the \@ifstar mechanism that allows star versions of commands. Commented Apr 5, 2011 at 22:02

    @araz: you probably don't really want to redefine \chapter or any of the related commands. Most of the time, people just want to redefine how a chapter heading is formatted or similar. You may want to post a more specific question if that sort of thing is your ultimate goal. Commented Apr 6, 2011 at 0:26

It doesn't exist on standard distributions. Try asking kpsewhich latex.ltx at the command prompt; the directory that file is in contains the files that make up the heart of Latex.


If you just want to look at latex.ltx and don't want to worry about messing up your system, you can look at the version here:


I assume this should be good enough if your system is reasonably up to date.
