Question about groff file

[Grégoire Babey]

Hi groffies!

I reading the manual again.
There is something I don't understand.
I read in the manual, at chap. 2.6:

"groff file

This command processes file without a macro package or a preprocessor.
The output device is the default, ‘ps’, and the output is sent to
stdout."

I tried this with a simple file named aa, containing only two
characters. "aa". If I type:

groff aa

I should find at some place a file named aa.ps. But there is nothing.
I was searching with locate:

locate aa.ps

gives no results.

I have found some directories named stdout, but there was no aa.ps
there.

Can somebody explain this to me?

Regards
Gregoire
