To keep the same order:
Code:
awk '
NR==FNR{a[$1]=++p;out[p]=$1;next}
{ for(i=1;i<=NF;i++)
      if($i in a){ 
        out[a[$i]]=out[a[$i]]"\n" $1
      }
}
END{
  for(i=1;i<=p;i++) {
    print out[i]"\n"}
}' file1 FS="," file2

       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
