Re: Sort textfile

You are using sort incorrectly.

sort returns the sorted array, it does not sort the array.

See example below:

perl -e '@a=(1,5,3);@b=sort @a; print "@a\n"; print "@b\n";'
[download]

with output

1 5 3
1 3 5

You have two problems in your code. (1) `sort @array` does not sort the array, it returns the sorted array (2) `sort {$a <=> $b} @array` sorts numbers, not strings. To fix this, use default sorting of sort (or explicitly compare strings) and assign it to a new array. `@sorted = sort @array;` [download] or `@sorted = sort {$a cmp $b} @array;` [download] Sandy	[reply] [d/l] [select]
