The problem is with the ;& body termination, which is used for "falling through" in case statements. I guess this is a Kornshell-only feature.

I have adjusted the code somewhat so that it works in both ksh and bash:

Code:

#!/bin/ksh
# First Step 2
mergedline=0
{ sed 's/^\([CDS]\) \(.*\)$/\2 \1/' infile |\
while read line; do
  case $line in
      # Step 3
      \[*) printf "$prevline $line\n"
           mergedline=1
           prevline="" ;;
      # Step 4
      *)   if [[ $mergedline -eq 0 ]]; then
             echo $prevline
      # Step 1
             case $line in
               *subnets*|*masks*) echo ;;
             esac
           fi
           mergedline=0
           prevline=$line  ;;
  esac;
done;
if [[ $mergedline -eq 1 ]]; then
  echo $prevline
fi } | \
while read firstline; do  # Step 5
  while read line; do
    if [[ $firstline != "" ]]; then
      echo $firstline
      firstline=""
    fi
    if [[ $line != "" ]]; then
      echo $line
    else
      break
    fi
  done|sort -n -t. -k1,1 -k2,2 -k3,3 -k4,4
  echo
done
if [[ $firstline != "" ]]; then
  echo $firstline
fi

And this version works in sh/dash too:

Code:

#!/bin/sh
# First Step 2
mergedline=0
{ sed 's/^\([CDS]\) \(.*\)$/\2 \1/' infile |\
while read line; do
  case $line in
      # Step 3
      \[*) printf "$prevline $line\n"
           mergedline=1
           prevline="" ;;
      # Step 4
      *)   if [ $mergedline -eq 0 ]; then
             echo $prevline
      # Step 1
             case $line in
               *subnets*|*masks*) echo ;;
             esac
           fi
           mergedline=0
           prevline=$line  ;;
  esac;
done;
if [ $mergedline -eq 1 ]; then
  echo $prevline
fi } | \
while read firstline; do  # Step 5
  while read line; do
    if [ -n "$firstline" ]; then
      echo $firstline
      firstline=""
    fi
    if [ -n "$line" ]; then
      echo $line
    else
      break
    fi
  done|sort -n -t. -k1,1 -k2,2 -k3,3 -k4,4
  echo
done
if [ -n "$firstline" ]; then
  echo $firstline
fi
