perl-watcher-engine-watcher-filetail

Inotify-based file tail watcher allows you to track changes (e.g. log file addons) on the particular file on filesystem.
Add to ~/.perl-watcher/engine.conf filetail watcher like:
{
class => 'App::PerlWatcher::Watcher::FileTail',
config => {
file => '/var/log/messages',
lines_number => 10,
filter => sub { $_ !~ /\scron/ },
},
},
