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?

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
