This works if the name column is added to the headers file:
Code:
awk '
NR == FNR       {T[$1] = NR
                 next
                }
FNR == 1        {MX = NR - 1
                 for (i=1; i<=NF; i++) if ($i in T) C[T[$i]] = i
                }
                {for (j=1; j<=MX; j++) printf "%s%s", $C[j], (j == MX)?RS:"\t"
                }
' file2 file1
name	col_1	col_6	col_3	col_4	col_8	
name,1	2	0	1	0	9.6154	
name,2	7	0	0	0	8.6310	
name,3	4	0	1	0.6	4.6420	
name,4	6	0	1	0	7.7778

NAME
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 SEE ALSO
