How to Sort Columns of Data (descending to ascending)?

Hello Everybody,

I have an ASCII file containing 3 Columns of descending data as
flollows:
.
.
.
3277.233 | 9.032167E-16 | 5.354040E-16
3276.725 | 1.825813E-15 | 7.552098E-16
3276.211 | 2.472245E-15 | 8.826818E-16
3275.699 | 2.943001E-16 | 3.192112E-16
3275.188 | 1.921011E-15 | 5.618553E-16
3274.677 | 1.089351E-15 | 4.211239E-16
.
.
.

I want to sort them in ascending order.

Does anybody know how to do it in Ubuntu 10.4.

I would be very grateful for any help.

With best regards,
Hassan

If thats not what you want:

Code:

sort --reverse filename

If the file is already sorted, the problem reduces to reversing the file:

Code:

tac file

Code:

sort filename > newfilename.txt



sort -r filename > newfilename.txt



tac filename > newfilename.txt
