[GRASS-user] r.fillnulls (GRASS BOOK 3rd edition)

[Luís Ferreira]

Hi

On page 123 of the book "Open Source Gis - A GRASS GIS Aproach", when
performing

GRASS 6.4.svn (nc_spm_08):~ > r.fillnulls elev_srtm_30m_null
out=elev_srtm_30mfilled

it gives me the errors

/usr/lib/grass-6.4.svn/scripts/r.fillnulls: eval: line 82: unexpected
EOF while looking for matching `''
/usr/lib/grass-6.4.svn/scripts/r.fillnulls: eval: line 83: syntax error:
unexpected end of file
/usr/lib/grass-6.4.svn/scripts/r.fillnulls: line 83: GISDBASE: parameter
null or not set

I'm starting using GRASS. Any suggestion to solve this?

Thank you
