替代未按预期字符串 - CMD /批次/注册表？ [英] CMD / Batch / Registry - String replace not working as expected?
问题描述
我有最有趣的尝试在code的一条线为Windows注册表项来替换子
I'm having the most fun trying to replace a substring in one line of code for a windows registry key
[HKEY_CLASSES_ROOT\PING\shell\open\command]
@="C:\\Windows\\System32\\ping.exe %1 -t"
情景和上下文：
的背景是一个自定义URL协议，将打开连续平一个shell到一个特定的IP，我想删除协议平：从URI // 这被作为过去了％1 。
相信我可以用一个批处理文件，但我preFER拥有这一切在一行在注册表
The context is a custom url protocol that will open up a shell with continuous ping to a specific ip and i want to remove the protocol ping:// from the uri that gets passed as %1.
sure i could use a batch file, but I'd prefer to have it all in one line in the registry
我已经试过：
到目前为止，我已经试过追加命令的列表，包括＆安培; 设置一个变种，然后呼应它。
so far I've tried appending a list of commands with & setting a var and then echoing it..
尝试呼叫设置删除=平：// ＆安培; 呼叫设置mynewvar = ％1：％=删除％ ＆安培; ping.exe的％mynewvar％-t
我试过用扩大变量几次<code> %%
I've tried expanding the variables a few times using %%
基本上我已经得到奇怪的结果或更换所有不工作
Basically I've been getting weird results or the replace not working at all
不知道我做错了吗？键入此，我开始觉得我俯瞰实际上它的字符串变种 @ =...
Not sure what I'm doing wrong? Typing this, I've started to think I'm overlooking the fact its in string var @="..."

注册表键
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\PING]
@="url:ping protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\PING\shell]
[HKEY_CLASSES_ROOT\PING\shell\open]
[HKEY_CLASSES_ROOT\PING\shell\open\command]
@="cmd /k set var=%1 & call set var=%%var:ping://=%% & ping.exe %var% -t"
在浏览器中键入URL 平：//8.8.8.8
的命令提示符输出 Ping请求找不到主机平：//8.8.8.8/ar。请检查该名称，然后重试。
我注意到 AR 之后，IP从％VAR％它的使用<$ C $出现C>％v 不是％VAR
I notice the ar after the ip is from %var% it appears its using the %v not %var
推荐答案
明白了.. ％V 实际
％V - 对于那些没有动词意味着一切。如果没有传递的参数，这是工作目录。
