Optimizing bash script
any way the following code can be optimized?

Code:
FIRSTIN=$(
        HKIPP=$(echo ${TMFR} | egrep -v "mo|MO|Mo" | egrep "m |M ")
        HRAMH=$(echo ${TMFR} | egrep "h|H")
        HRAMD=$(echo ${TMFR} | egrep "d|D")
        HRAMW=$(echo ${TMFR} | egrep "w|W")
        HKIPPO=$(echo ${TMFR} | egrep "mo|MO|Mo")
        if [ -z "${HRAMH}" ] && [ -z "${HRAMD}" ] && [ -z "${HRAMW}" ] && [ -z "${HKIPP}" ] && [ -z "${HKIPPO}" ] ; then
                echo $TMFR | sed 's~[hHmM]~~g' | gawk '{print $1 * 60}'
        elif [ ! -z "${HKIPP}" ] ; then
                echo $TMFR | sed 's~[hHmM]~~g' | gawk '{print $1 * 60}'
        elif [ ! -z "${HRAMH}" ] ; then
                echo $TMFR | sed 's~[hHmM]~~g' | gawk '{print $1 * 60 * 60}'
        elif [ ! -z "${HRAMD}" ] ; then
                echo $TMFR | sed 's~[dD]~~g' | gawk '{print $1 * 1440 * 60}'
        elif [ ! -z "${HRAMW}" ] ; then
                echo $TMFR | sed 's~[wW]~~g' | gawk '{print $1 * 10080 * 60}'
        elif [ ! -z "${HKIPPO}" ] ; then
                echo $TMFR | sed 's~[mo]~~g' | sed 's~[MO]~~g' | sed 's~[Mo]~~g' | gawk '{print $1 * 43200 * 60}'
        else
                echo $TMFR | gawk '{print $1 * 60}'
fi)

preferably in awk?
