* 日志文件路径

结果会异步保存在：`{user.home}/logs/arthas-cache/result.log`，请定期进行清理，以免占据磁盘空间

### 使用新版本Arthas的异步后台任务将结果存日志文件
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
$ trace Test t >> &
|
|
|
|
|
|
job id : 2
|
|
|
|
|
|
cache location : /Users/admin/logs/arthas-cache/28198/2
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
此时命令会在后台异步执行，并将结果异步保存在文件（~/logs/arthas-cache/${PID}/${JobId}）中；
|
|
|
|
|
|
|
|
|
|
|
|
* 此时任务的执行不受session断开的影响；任务默认超时时间是1天，可以通过全局 `options` 命令修改默认超时时间；
|
|
|
|
|
|
* 此命令的结果将异步输出到文件中；此时不管 `save-result` 是否为true，都不会再往~/logs/arthas-cache/result.log 中异步写结果
