Did I understand points 1) and 2) correctly? This script finishes a list of almost 640,000 entries in less then a minute (50sec), adding conditions 3) and 4) should be really easy.
#!/usr/bin/perl use feature 'say'; use warnings; use strict; my $file = '/etc/dictionaries-common/words'; open my $IN, '<', $file or die "$!"; my %words; while (my $word = <$IN>) { chomp $word; undef $words{$word}; } for my $word (keys %words) { my $length = length $word; my %found; # report each occurence just once for my $pos (0 .. $length - 1) { my $skip_itself = ! $pos; for my $len (1 .. $length - $pos - $skip_itself) { my $subword = substr($word, $pos, $len); next if exists $found{$subword}; if (exists $words{$subword}) { say "$subword in $word"; undef $found{$subword}; } } } }
Update: if I ommit the "just once" condition, the script finishes in 40 secs on my Mac Mini.
