Help on sort in Unix

Hi all,

I am a new user on this forum. nice to meet u all.
I am a newbie on Unix and current having problem to solve my problem with the sort command.

I have a file with 2 columns as the following:
0001 0012
0002 0089
0003 1234
0001 4567
0008 2456
0003 0028
0001 1011
0002 1112

I want to sort the first column in ascending order and then within the sorted first column, sort the second column in descending order.
The following is the desire output:
0001 4567
0001 1011
0001 0012
0002 1112
0002 0089
0003 1234
0003 0028
0008 2456

Can anyone help me please? any help is appreciated.
Thanks, Cheers

Oh, i have solved the problem.
For the sake of any new Unix user, like me, might want to know.
Here is the solution I used.

I solved it with multiple keydef (the -k option)

the command is:
sort -k 1,1 -k 2,2r infile.txt

this sorts the first column first, and then sorts the 2nd column in reverse order.

Cheers

????????????????? what does:
sort -k 2,2r infile.txt

-k 2,2r IGNORES -k 1,1

Sorry again, sheriff, you are barkling up the mistaken tree.

I have tried the snowmen's suggestion on Solaris and on AIX. On both systems is it OK.

Show us YOUR ORIGINAL solution please.

Congratulations! You have another post. You will get a better belt color. But the belt color does not say anythig about the bearer's quality.
