Make sure your scripts only produce output on error. This sometimes
requires a trivial wrapper script:

#!/bin/sh

CMD="/full/path/to/my/script arg1 arg2 ... argn"
TMP_FILE=/tmp/`basename "${CMD}"`.`date +'%Y-%m-%d_%H-%M-%S'`

${CMD} 2>&1 >"${TMP_FILE}"
retval=$?

if test ${retval} -ne 0; then cat "${TMP_FILE}"; fi

rm "${TMP_FILE}"
exit ${retval}
