Change working directory

[C.G.Senthilkumar.]

Hi,

Is there a way I could ask latex to change current working directory?
The following is my scenario:

I have a project report written in latex and it uses the project results
from a sub-directory as shown below.
$ pwd
HOME/project/report
$
$ grep input article.tex
\input{../src/data/results.tex}
$
$ latex article.tex

Now, I want to include that report, amongst others, in my dissertation.
$ cd ../../dissertation
$ grep article dissertation.tex
\input{../../project/article.tex}
$ latex dissertation.tex

Now latex can't find my ../src/data/results.tex that is \input{} from
article.tex file because the current working directory is
HOME/dissertation and there is no sub directory called src.

Thanks in advance.
Senthil.

No (not even with \write18, because it would only change the working
directory of the subprocess).

* You can use the environment variable TEXINPUTS, e.g.
export TEXINPUTS=.:~/project/report:

* \input@path could be defined, e.g.
\makeatletter
\providecommand{\input@path}{}
\renewcommand*{\input@path}{\input@path{../../project/}}
\makeatother

The simplest way is to say in dissertation.tex something like
\def\datadir{../project/src/data}

and in article.tex
\makeatletter
\ifx\datadir\@undefined\def\datadir{../../src/data}\fi
\makeatother

Then you can use \input{\datadir/results.tex}, and \datadir will
expand to the proper directory.

Heiko gave a way for tex to become aware of the path globally, and
Boris gave a useful way for tex to expand a pathname in the latex
document.

I would suggest another way also: you could create symbolic links in a
directory that is already on the tex path (e.e., current directory) to
all the non-local files you want to include. I always do that instead
of copying files since then I only have to modify the original files
(generated .eps figures, for example) and it also allows me to keep a
local name for the distant files (often shorter or names more
compatible with tex demands, such as no active characters in the
names).
