I have a file like this...

2183842512010-11-25   15379043  453130325
2386225062010-11-30    4946518  495952336
2386225062010-11-30    4946518  495952345

I wantr to sort the file based on two fields :-
a) first field position -- 1 to 9
218384251
238622506

b) second field position -- 10 to 19
2010-11-25
2010-11-30

i tried using sort -k1,9 -k10,19 file_name but i didn't get any output
Experts pls provide your inputs..

sort -k1,9 file | sort -k10,19

Edit: Scott was faster :slight_smile:

my @arr=<DATA>;
print map {$_->[2]} sort {$a->[0]<=>$b->[0] || $a->[1]<=>$b->[1]} map {my($a,$b,$c,$d)=$_=~/^(.{9})(.{4})-(.{2})-(.{2})/;[$a,$b.$c.$d,$_];} @arr;

I don't think splitting the first field affects the sort order in this case...

sort -k1,1 infile
