Input files whose names are dates

Question

I have a lot of files named by date, e.g., 20151118.tex, 20151117.tex, 20151116.tex, etc. These in a directory separated by month and year (2015/11/20151118.tex).

I would like to input these files without having to have to have the following in my main file:

.
.
\input{2015/11/20151117}
\input{2015/11/20151118}

Is there a way to do this with LaTeX. I would like a clean way to do this, if at all possible.

Answer 1

If you want to incorporate my suggestion above into a single file, this is one approach. The shell commands would need to be different on Windows:

\documentclass{article}

\immediate\write18{ls -R -1 */*/*.tex > filelist.dat}
\immediate\write18{sed -i 's/^/\noexpand\\input /' filelist.dat}%

% For more info, see: http://tex.stackexchange.com/q/25168/8528
\newread\myfile
\newcommand*\readfile{%
    \immediate\openin\myfile=filelist.dat\relax
      \loop
        \read\myfile to \mydata
        \unless\ifeof\myfile
            \mydata\par% <-- note the \par here (may not necessarily be desired)...
      \repeat
    \immediate\closein\myfile
}

\begin{document}

\readfile

\end{document}
