Sorting Help Please Can't Post
When I open my text file that is formated like this and read it into an array:

90|Quake|30|
543|Unreal|29|
543|Half Life|29|
543|Unreal Tournament|29|

I need to sort the array by the second column only alphabetically (i.e. the game name) Can this be done?

Thanks

Hi casManG

This will work for you::


open(CURE, "cure.txt") or die "coudlnt open file. $!";

map { print $_->[0] } sort { $a->[2] cmp $b->[2] } map{ [$_ ,
split(/\|/)] } <CURE>;

close(CURE);

Hey Cure,
Thanks for that but I was stupid and forgot to mention that I dont want to print but I want to store what you have it printing back into an array so that if I just have a
print @arrayname;
Then it would print sorted. Can this be done? Sorry for not being more clear before.

Thanks
casManG

-ACTUALLY-
I think I got it working now using a push. Please tell me if I am doing this a bad way but here is what I have:

map { push (@casManG, $_->[0]) }
sort { $a->[1] cmp $b->[1] }
map{ [$_ , split(/\|/)] } @data ;

Which puts it into the @casManG.
Is this a good way to do it?

Later
casManG
