tail($file)

This function will tail the given file.

 task "syslog", "server01", sub {
   tail "/var/log/syslog";
 };

If you want to control the output format, you can define a callback function:

 task "syslog", "server01", sub {
   tail "/var/log/syslog", sub {
    my ($data) = @_;
 
    my $server = Rex->get_current_connection()->{'server'};
 
    print "$server>> $data\n";
   };
 };
