Sort two columns in a field, one of them being a date
Hi,

I have a set of columns in a csv file, my first row being an integer and 2nd being a date. I want to first sort it using the first column and then by the second.

for e.g. i have ,

1234,09/05/2009,hi
5678,01/01/2008,hi
1234,11/03/2006,hello
5678,28/07/2010,hello

i tried this but wont work because the separator is "," :::

sort -t "," -k1 -k2.7,2.10 -k2.4,2.5M -k2.1,2.2 test.csv > hi.csv

Thanks in advance,
SD
