merge two files in ascending order
Hello Friends,

I want to merge two files in ascending order on the first field. And if the first field matches sort on 3rd field i.e, TXADDR should come ahead of RXADDR .

file1
Code:
      9 : TXADDR  : 00000000
     65 : TXDATA  0000000000000011
     83 : TXDATA  0000000000000012
    453 : TXADDR  : 00000000
    509 : TXDATA  0000000000000001
    527 : TXDATA  0000000000000002
    879 : TXADDR  : 00000020
     934 : TXDATA  0000000000000011
     953 : TXDATA  0000000000000012
     971 : TXDATA  0000000000000013
file2
Code:
        9 : RXADDR  : 00000001
      65 : RXDATA  0000000000000011
      83 : RXDATA  0000000000000012
     102 : RXDATA  0000000000000013
     453 : RXADDR  : 00000000
     509 : RXDATA  0000000000000001
     527 : RXDATA  0000000000000002
     546 : RXDATA  0000000000000003
     879 : RXADDR  : 00000020
     934 : RXDATA  0000000000000011
     953 : RXDATA  0000000000000012
     971 : RXDATA  0000000000000013
     990 : RXDATA  0000000000000014
WIth the below command I able to sort and merge on the first field.
Code:
sort -n file1 file2 > file3
In file3 I expect when the first column matches it should give priority to the 3rd column i.e RXADDR & RXDATA.
So in my case the output should be
Code:
      9 : TXADDR  : 00000000
      9 : RXADDR  : 00000001
    65 : TXDATA  0000000000000011
    65 : RXDATA  0000000000000011
I dont know how sort with multiple key with sort pls suggest a option for that. or any other soln.

Regards,
user_prady

The following will sort first by the first key, numerically, and then by the second key alphabetically:

Code:
sort -k1,1n -k2,2 file1 file2 > file3

Actually, you'll want -k3,3 not -k2,2... but you probably figured that out yourself!

Thanks for your kind replies , but both the command outputs the same as
the command
Code:
sort -n file1 file2 > file3
I want to reverse the third column so that TXADDR/TXDATA comes before RXADDR/RXDATA when the first column matches . The above commands gives me the reverse..
