Hello,
I just need help in concatenating commands...
I build a command that, given a East and North coordinate scan a raster finding the nearest cell with value majon than a treshold...
> r.nearest.coor input=accum100a threshold=500 radius=20 easting=692019.11712163 northing=119228.853597
this is the output of the command....
> easting=690796.625000 northing=119081.002604
I want now call the r.watershed.outlet.... concatenating this output...
> r.water.outlet drainage=drainage100 basin=mybasin (easting=...... northing=........)
if I run:
> r.nearest.coor input=accum100a threshold=500 radius=20 easting=692019.11712163 northing=119228.853597 | r.water.outlet drainage=drainage100 basin=a7642899097zzoo
I have the message that r.water.outlet need easting and northing parameters......
What to do?
Thanks

What to do?
Provide easting and northing to r.water.outlet 
These are parameters, I don't think that r.water.outlet reads from
stdin (pipe). So you have to slightly modify the last command.

I've found....
r.water.outlet drainage=drainage100 basin=a7642899097zzooAAZ123 `r.nearest.coor input=accum100a threshold=500 radius=20 easting=694109.756531 northing=113416.282572`
that's it........
Ciao
