exec参数介绍  
command : 指定要执行的命令。如果忽略，这个参数的值默认为资源的标题。必须填写命令的完整路径或者提供这个命令的查找路径。假如命令执行成功，执行过程的输出将会记录到普通 (normal)日志中,但是如果命令执行失败，任何的输出都会记录到错误日志中。  
creates : 命令创建的一个文件。加入这个参数设置的话，只有这个文件不存在的时候命令才会执行，比如下面的例子;

上例中，只有/var/lib/puppet/report文件不存在的时候，command 中的命令才会执行，也就是生成report文件，某种意义上creates表明的结果  
cwd : 命令执行的路径。假如目录不存在，命令执行将会失败。  
environment : 为命令设置附加的环境变量。加入你用这个参数设置PATH，那么将会把path参数的值覆盖。多个环境变量需要使用数组指定。  
user ： 定义运行命令的用户。 注意如果你使用了这个参数，那么任何的错误输出不会在当下被捕捉，这是Ruby的一个bug。  
group : 执行命令运行的用户组。这个看起来在各个平台运行结果不确定，这是平台的问题不是ruby或者puppet的问题。  
logoutput : 是否记录输出信息。默认会根据exec资源的日志等级来记录输出信息，使用on\_failure只有当命令执行出错的时候才会记录输出信息。值可以为true、fales、on\_failure和任何合法的日志等级。  
onlyif : 只有onlyif指定命令执行返回为0的时候，命令才会执行

上面表明当test.file存在的时候才执行command命令  
path : 命令执行搜索的路径。如果没有指定path，命令需要填写完整的路径。路径可以指定为一个数组并通过冒号分隔。  
如：

refresh ： 定义如何更新命令。当exec收到一个来自其他资源的事件时，默认只会重新执行一次命令。不过这个参数允许你定义更新时执行不同的命令。  
refreshonly ： 该属性可以使命令变成仅刷新触发的，也就是说只有在一个依赖的对象被改变时，命令才会被执行。仅当命令与其他对象有依赖关系时，这个参数才有意义。当你要触发某个行为时，会显得很有用：  
要注意的是只有subscribe和notify可以促发行为，而不是require，所以在使用refreshonly时，只有同时使用subscribe或notify才有意义。有效的值为true, false。  
returns ： 指定返回的代码。如果被执行的命令返回了其他的代码，一个错误（error）会被返回。默认值是0，可以定义为一个由可以接受的返回代码组成的数组或单值  
timeout ： 命令运行的最长时间。如果命令运行的时间超过了timeout定义的时间，那么这个命令就会被终止，并作为运行失败处理。当定义为负值时就会取消运行时间的限制。timeout的值是以秒为单位的。  
unless ： 如果这个变量被指定了，那么exec会先执行，除非unless所设定的命令返回0。例如：

上面这段代码先用grep在cron.allow文件（Solaris系统中）中找root，如果没有找到，就写入root。  
要注意的是这个参数里的命令跟主命令遵循同样的规则，也就是说如果path没有被设置的话，需要使用绝对路径。  
案例1、让/var/www/html/index.html文件修改时就自重启httpd服务
