Augusto, great news :) I'll test it in my geomorphological work surely. You
would not want to add it to GRASS-Addons wiki page (
http://grass.osgeo.org/wiki/GRASS_AddOns)?

One note: in GRASS shell scripts it's usually better to use:

-- module <g.message> instead of standard "echo"

-- special temp files (made with g.tempfile):

# create temporary file
TMP1="$(g.tempfile pid=$$)"
if [ "$?" -ne 0 ] || [ -z "$TMP1" ] ; then
    g.message -e "ERROR: Unable to create temporary files."
    exit 1
fi


-- cleanup function and some actions for the case of user exit

############################################################
cleanup()
{
    g.mremove -f vect=MY_TEMP_VECTOR --q
    rm -f $TMP1*

}
############################################################
## what to do in case of user break:
exitprocedure()
{
    echo "User break!"
    cleanup
    exit 1
}

## shell check for user break (signal list: trap -l)
trap "exitprocedure" 2 3 15
