in reply to Re^5: String sorting in Perl
in thread String sorting in Perl
Thanks! I think it should be "count_hash" instead of "hash_count", though. Before I read your post, I worked out this solution:
#!/usr/bin/perl -w use strict; my $file = "path to my file"; open (FH, "< $file") or die "Can't open $file for read: $!"; my @data = <FH>; close FH or die "Cannot close $file: $!"; my %count_hash; for my $line (@data) { $count_hash{$line} ++; } for my $line (sort { length $a <=> length $b || $count_hash{$b} <=> $c +ount_hash{$a}} keys %count_hash) { print "$line\t$count_hash{$line}\n"; }
The only thing I see is that it seems to carry over the line break with each line, so the count ends up being on a new line, tabbed over. Is there a way to have it look for a line break and remove it before it prints>
