See the notes and output sections of the g.findfile manpage. There you can find additional information how to use the comand in scripts.

Uhm. I have tried that one with  
g.findfile element=raster file=L (I have a raster map named L in my mapset) and I get:
name=
mapset=
fullname=
file=
Which would mean that it doesn't exist.


is there any other way to do this for GRASS-pythons scripts?

  Try e.g "g.findfile element=vector file=testmap"

  Hi 


  I'm doing a python script and, in a process, I need to check if a raster map exists. My idea is, if this map exists I don't need to create otherwise, I need to create it (v.to.rast). Is there a way to check if a map exists in the current mapset?
  Thanks
  Helena
