Hi Xavier,
It might be as easy as this:
for TILE in `find /path/to/tiles -type f`; do
echo "${TILE}"
FILE=`basename "${TILE}"`
L1=`dirname "${TILE}" | gawk -F"/" '{ print $NF}'`
L2=`dirname "${TILE}" | gawk -F"/" '{ print $(NF-1)}'`
curl --output "${TILE}"
http://tile.openstreetmap.org/"${L2}"/"${L1}"/"${FILE}"
done
curl and http are on the same line, you mail program might split in over
two lines.
Kind regards,
Ed
