Tools_004：使用Handle查看进程打开的文件

Handle是查看系统进程打开文件的程序。
当系统抛出java.io.IOException: Too many open files异常时，使用该程序可以帮助我们确认哪些进程打开了哪些文件。

使用方法：
usage: handle [[-a [-l]] [-u] | [-c [-y]] | [-s]] [-p |][name]
-a Dump all handle information.
-l Just show pagefile-backed section handles.
-c Closes the specified handle (interpreted as a hexadecimal number).You must specify the process by its PID. WARNING: Closing handles can cause application or system instability.
-y Don't prompt for close handle confirmation.
-s Print count of each type of handle open.
-u Show the owning user name when searching for handles.
-p Dump handles belonging to process (partial name accepted).
name Search for handles to objects with (fragment accepted).

No arguments will dump all file references

比如，如果想看看所有java进程打开的文件，可以这样写：handle -p java.exe >output.txt。
输出可能如下：
java.exe pid: 1288 PMA-GLACIER\pma
