Comparing two files and inserting new fields
Hi all,

I searched the forum and tried to learn from the similar posts. However, I am new and I need to get help on this. I hope an expert kindly help me to sort this out.

I need to compare field 1 and 2 of the first file with the same fields of the second file and if both fields matches insert the field 9 and 10 of the second file to the position 1 and 2 of the first file.

1st file:

Here you go

(With Fn headings in input files and output)
Code:
awk 'NR == FNR { A[$1"|"$2]=$9; B[$1"|"$2]=$10; OFS="\t" ; next}
 FNR == 1 { printf "F1\tF2\tF3\tF4\tF5\tF6\tF7\tF8\tF9\tF10\tF11\tF12\tF13\tF14\tF15\tF16\n" }
 FNR > 1 { print A[$1"|"$2], B[$1"|"$2], $0; } ' fileB fileA

(Without Fn headings)
Code:
awk 'NR == FNR { A[$1"|"$2]=$9; B[$1"|"$2]=$10; OFS="\t" ; next}
 { print A[$1"|"$2], B[$1"|"$2], $0; } ' fileB fileA

@Chubler_XL

Your output is right, because FileA (1st file) 's $1 and $2 are all in FileB (2nd file). If there are some different, you still print without $9,$10.

I change one number in 1st file.

Code:
F1      F2      F3      F4      F5      F6      F7      F8      F9      F10     F11     F12     F13     F14     F15     F16

                180191  99999   51255   1       19      16      3       5       10      0       55      0       0       7
54261   210546  999999  13721   12548   1       20      9       -12     7       -1      0       66      0       0       7
65971   245695  180193  99999   51255   1       19      16      3       5       10      0       55      0       0       7
22976   236598  999999  15264   11446   1       22      10      -9      9       1       0       64      99999   99999   99999
26980   265986  170265  99999   15960   1       26      17      3       12      8       0       54      0.01    99999   8

Here is my code with headings.

Code:
awk 'NR==FNR {A[$1 FS $2]=$9 OFS $10; next}
FNR==1 {for (i=1;i<=NF+2;i++) printf "F"i OFS ;printf ORS}
FNR >1&&($1 FS $2 in A) { print A[$1 FS $2], $0; } '  OFS="\t"  FileB FileA

Good point, but in my defense the original request wasn't specific about what should be output when a match wasn't found. It's probably slightly safer to put blank values for 9 and 10 rather than hiding the whole row.

BTW, I also considered a for loop to print the headings, but I suspect the real data has no headings or data specific headings that the OP renamed for ease of reference.

Great idea to use 9 OFS 10 as the hash array data.

Chubler_XL and rdcwayx ,
I can't thank you enough for your time and help.

My data has no headings and I just put them to make my code clear.
I tried
Code:
awk 'NR == FNR { A[$1"|"$2]=$9; B[$1"|"$2]=$10; OFS="\t" ; next}
 { print A[$1"|"$2], B[$1"|"$2], $0; } ' fileB fileA

the fields that added to my fileA aren't correct. Something must be wrong with it. I test your codes with headings and let you know if it works.
Thanks again!

Be careful you put the files on the awk command line in the correct order (FileB = your 2nd file) (fielA = your 1st file).

Here is a transcript of my test (with slight enhancement - Use FS instead of "|" in array index - thanks rdcwayx).
I kept the two arrays as this ensures the output has the same number of fields when lookup of fields1 and 2 don't find any data.
Code:
$ cat fileA

$1 FS $2 in A { print A[$1 FS $2], $0; } '  OFS="\t"  FileB FileA
