# Where can I find file latex.‎tex?

Where can I find file latex.‎tex?‎ I don't have it in my tex ‎distribution‎. I‎ ‎have ‎only ‎file ‎latex.ltx ‎on ‎my ‎system.
By the way, I'm using Texlive 2010.

Why do you think a latex.tex should exist? latex.ltx is the right file which contains the latex code. –  Ulrike Fischer Apr 5 '11 at 14:05
Why do you need to find such a file? –  ℝaphink Apr 5 '11 at 14:05
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. –  Martin Scharrer Apr 5 '11 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. –  Andrey Vihrov Apr 5 '11 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. –  Mike Renfro Apr 6 '11 at 0:26

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:

mirrors.ctan.org/macros/latex/unpacked/latex.ltx

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

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.
