Alternative in shell :
Code:
while read line; do
  if match=$(grep "${line%%,*}" file2); then
    printf "$line\n$match\n"
  fi
done < file1 > file3

Output:
Code:

Not as efficient as awk though for large numbers but perhaps good enough.
Scrutinizer: you can use gawk or nawk and the o/p order will be as requested
