if you don't mind a trailing comma, you can do it in one line
Code:
tr "\n" "," < in > out

if not:
Code:
#!/bin/sh
touch out
LINECT=`cat in|wc -l`
COUNTER=1
while read line
do
  if [ ${COUNTER} -lt ${LINECT} ]
  then
     echo $line|tr "\n" "," >> out
  else
     echo $line >> out
  fi
  COUNTER=`expr $COUNTER + 1`
done < in
