If you just need to script GRASS commands, it's easier to just run a
script from within a GRASS session than to script the creation of the
session.

This probably won't harm anything, but it's better to use Cygwin
pathnames for files and directories within the Cygwin hierarchy, i.e.:
GISBASE="/usr/local/grass-6.2.2"

Multi-line strings aren't robust; it's better to use either a
here-document:
cat > "$HOME/.grassrc6" <<-EOF
GISDBASE: $GISDBASE
LOCATION_NAME: newset
MAPSET: PERMANENT
EOF
or a subshell:
(
echo "GISDBASE: $GISDBASE"
echo "LOCATION_NAME: newset"
echo "MAPSET: PERMANENT"
) > "$HOME/.grassrc6"
or multiple commands appending to the file:
echo "GISDBASE: $GISDBASE" > "$HOME/.grassrc6"
echo "LOCATION_NAME: newset" >> "$HOME/.grassrc6"
echo "MAPSET: PERMANENT" >> "$HOME/.grassrc6"
> export LD_LIBRARY_PATH=/cygdrive/c/cygwin/lib:$GISBASE/lib:$LD_LIBRARY_PATH
LD_LIBRARY_PATH is specific to Linux and SunOS/Solaris. Windows
(including Cygwin) uses PATH to located DLLs:
export PATH="$GISBASE/lib:$PATH"
[Cygwin's DLLs are in its "bin" directory, which will already be in $PATH.]
It's probably the fact that $GISBASE/lib is missing from $PATH that's
preventing your script from working. If a Cygwin binary cannot find
its DLLs, it simply terminates without error.
