Hi All,
I am encountered with a problem while sorting a file based on multiple columns . I need to sort like:
(field2,ascending) , (field3,ascending) ,(field8,descending) , (field7,ascending),(field13,ascending).
So far i was sorting only in ascending order but here i need to use one descending field also.
Please see the sample text which needs to be sorted based on above rule.The text is TAB delimited.

200902010606 0001319 2113743L17 0 IDEN 0 0 0 0 0 NULL AK
Previously i was using sort like
sort -t "`echo -e "\t"`" +1 -2 +2 -3 >tmp This sort file using 2nd and 3rd field in ascending order only having TAB as delimiter.
Please help me to sort it out.
Thanks
