How can I get the following to prompt me for new values for the dacsrtrspans?

example I want to change the span #, sinktermmod, sinktermport, srctermdev and srctermport to new values.

old:

ADD DACSRTRSPAN-1-840 SINKTERMMODULE=8 SINKTERMPORT=94 SRCTERMDEV=1 SRCTERMPORT=1 SPANTYPE=T1_2 SRCSPANEQ=T1_1 SINKSPANEQ=T1_1

ADD DACSRTRSPAN-1-841 SINKTERMMODULE=8 SINKTERMPORT=95 SRCTERMDEV=1 SRCTERMPORT=2 SPANTYPE=T1_2 SRCSPANEQ=T1_1 SINKSPANEQ=T1_1

to NEW:

ADD DACSRTRSPAN-1-600 SINKTERMMODULE=6 SINKTERMPORT=1 SRCTERMDEV=1 SRCTERMPORT=1 SPANTYPE=T1_2 SRCSPANEQ=T1_1 SINKSPANEQ=T1_1
ADD DACSRTRSPAN-1-601 SINKTERMMODULE=6 SINKTERMPORT=2 SRCTERMDEV=1 SRCTERMPORT=2 SPANTYPE=T1_2 SRCSPANEQ=T1_1 SINKSPANEQ=T1_1

by using a script

printf "\n\nAdd the packet backhaul connections
===================================\n" >> $outfile
for btsrtrgrp in `displayrc bts-$bts con | grep PKTBTSCON | awk '{print $1}' | grep "[0-9]\{1,4\}-[0-9]-[0-9]"`; do
 
   #   Determine if the connection has DACSRTRSPANs or AGNODESPANs
   if displayrc btsrtrgrp-${btsrtrgrp} con | grep $btsrtrgrp | grep DACSRTRSPAN > /dev/null; then
      #   Add DACSRTRSPAN(s)
      for dacsrtrspan in `displayrc btsrtrgrp-${btsrtrgrp} con | grep DACSRTRSPAN | sed 's/^.* \(DACSRTRSPAN\-[0-9]\{1,5\}\-[0-9]\{1,5\}\) .*$/\1/'`; do
         sinktmod=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $8}' | cut -f1 -d"/" | sed 's/Dacs//'`
         sinktport=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $8}' | cut -f2 -d"/"`
         srctdev=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $4}'`
         srctport=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $5}' | sed 's/physical\-//'`
         spantype=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $2}'`
         srcspaneq=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $6}'`
         sinkspaneq=`displayrc $dacsrtrspan spanconf | grep BTSRTRGRP | awk '{print $9}'`
         printf "ADD $dacsrtrspan SINKTERMMODULE=${sinktmod} SINKTERMPORT=${sinktport} SRCTERMDEV=${srctdev} SRCTERMPORT=${srctport} SPANTYPE=${spantype} SRCSPANEQ=${srcspaneq} SINKSPANEQ=${sinkspaneq}\n" >> $outfile
      done
      printf "."

Thanks
