You could probably use this (I didn't tested), but it may leave stall
processes behind:

#!/usr/bin/perl

use strict;
use warnings;

$SIG{'ALRM'} = sub {
  print "CRITICAL: foo\n";
  exit 2;
};

alarm(60);
my $text = `/bin/bash /path/to/plugin.sh`;
my $result = $?>>8;
alarm(0);

print $text;
return $result;
__END__

If you need to kill stale processes, it's a bit more complicated - look
at my check_rsync v1.02 plugin for an example.
