Snort+Guardian中guardian无法启动？

oranger2001

系统是linux,shell是Bsehll，我是参照下面的文章做的
http://bbs.chinaunix.net/forum/29/050118/484898.html
启动提示错误
ERROR！Could not find guardina_block.sh. Please consult the README.
我读了readme和guardian.pl
readme有一段描述如下：
Guardian is now more modular than ever. When it decides to block an IP ip address, it calls a script called "guardian_block.sh" . I have included several sample scripts in the scripts directory of the Guardian package.The biggest benifit of this is that now you can have this script do whatever you like, from paging you, sending you email, or even to launch a counterattack (although I do not support or encourage such actions).

guardian.pl也有一段读取变量

foreach $mypath (split (/:/, $ENV{PATH})) {
    if (-x "$mypath/guardian_block.sh" {
      $blockpath = "$mypath/guardian_block.sh";
    }
    if (-x "$mypath/guardian_unblock.sh" {
      $unblockpath = "$mypath/guardian_unblock.sh";
    }
  }
  if ($blockpath eq "" {
    print "Error! Could not find guardian_block.sh. Please consult the README. \
n";

我不懂shell，呵呵，太菜了嘛。我改写.bash_profile的path
path=$pathHOME/bin:/usr/local/bin 黑体是我加的，但是没起作用！请各位帮忙！

在/etc/rc.local文件中加入
/usr/bin/perl /usr/local/bin/guardian.pl -c /etc/guardian.conf
不能正常启动，后来我进入系统在命令行下输入
#/usr/bin/perl /usr/local/bin/guardian.pl -c /etc/guardian.conf
guardian确可以启动了，这是为什么？
为什么加在rc.local中不行，单独输入没问题。我肯定没写错！！！
