[GRASS-user] capacity

GRASS GRASS user

I am using GRASS(6.3)
on a Mac OSX
fails at length 100(for when using g.mlist for my rasters)
Fails at length 240(when using r.region to change location of raster)

        I might have completely missed the point, but may the following
        help?

GRASS> g.mlist type=rast pattern="prefix*" \
           | (while read r; do r.region map="$r" ...; done)

        (I'm assumed that you've ran into a limit of command line
        length; since the above loop doesn't try to put all the map
        names into a single command, but rather issues a separate
        command for each of the maps, it should overcome the limit.)

Yes, it probably will work using Ivan's method. You didn't miss
anything, noone had suggested it before.

If it still fails, we'd need to see the code snippet causing the error.
