Saewan,

I am chiming in late, I realise, but you could structure it this way:

for i in `g.mlist rast pattern="*1987*ppds`; do
r.series input=$i output=test1987dd0 method=sum --overwrite;
done

Note that the g.mlist command is surrounded by "tick marks", not single quotes.

This structure works fine for me in either OSX or Linux terminals for other
activities. The downside is that instead of running all the input maps at once,
it will do the processing accumulatively, which would be slow if you have lots
of input rasters.
