Something is wrong... While my list has no double entries (I
cross-checked with "sort -u" the output of "db.tables -p"), wget
downloaded 262 tiles two times, another 56 tiles three times and another
8 tiles four times!!

Why is that? Connection problems? Most of the double files have the same
size.

Here how I go about it (for all available reference-grid shapefiles):
# check per-country 100k reference-grid-cells
db.tables -p | grep -v grid

# count tiles from attribute tables

# cross-check for double entries
## but, is this possible in a "clean" geo-attribute table after all?
for x in `db.tables -p | grep -v grid`; do db.select -c $x | cut -d"|"
-f2 | sort -u; done | wc -l

1362


# create a tiles-list
for x in `db.tables -p | grep -v grid`; do db.select -c $x | cut -d"|"
-f2; done > corine_v2_tiles_list_europe

# get tiles
for x in `cat corine_v2_tiles_list_europe`; do wget
http://dataservice.eea.europa.eu/staticfiles/landcover_tiles_v2/$x.zip
-a wget_corine_v2_tiles_europe.log && echo "Tile $x downloaded"; done
## unfortunately I used the log in the wrong way initially: instead of
"-a" I used "-o" which overwrites for each loop an existing log :-(

# check results
# total number of downloaded tiles agrees with the above mentioned count
# but... there a lot of double- and triple-downloaded tiles.

Any clue what's messing up this attempt?
