Escape "double quotes" inside batch's input parameters
提问by laggingreflex
I want to run the following in batch script where it takes an argument (a path)
我想在批处理脚本中运行以下内容，它需要一个参数（路径）
runas /user:abc "icacls %1 /grant Everyone:(F) /T"
but the argument %1already contains a "(because it's a path, passed on by context menu's Send To - I don't have much control over this).
So when the command runs in batch script it runs like this:
但是参数%1已经包含一个"（因为它是一个路径，通过上下文菜单的发送到传递 - 我对此没有太多控制权）。因此，当命令在批处理脚本中运行时，它的运行方式如下：
runas /user:abc "icacls "c:\folder" /grant Everyone:(F) /T"
So obviously I need to escape the "s created by %1. How do I perform string manipulation over %1such that it escaped the quotes?
所以显然我需要转义"由%1. 如何执行字符串操作%1以使其转义引号？

Each response covers part of the answer. Combining them using backslash & quote: \"you get:
每个回答都涵盖了答案的一部分。使用反斜杠和引用将它们组合起来：\"你得到：
runas /user:abc "icacls \"%~1\" /grant Everyone:(F) /T"
or you can doubled (double) quotes to escape them:
或者你可以加倍（双）引号来逃避它们：
runas /user:abc "icacls ""%~1"" /grant Everyone:(F) /T"
As a side note ^is occasionally useful for escaping special characters such as <, |, >, ||, &&, and &For example:
作为旁注^，有时可用于转义特殊字符，例如<, |, >, ||, &&, and&例如：
echo ^|
but this is pretty rare.
但这很少见。

SET myPath=%1
SET myPath=%myPath:"=\"%
runas /user:abc "icacls %myPath% /grant Everyone:(F) /T"
Edit - The variable name was changed from pathto myPath. PATH is a reserved system variable that should not be used for anything other than what it was intended.
编辑 - 变量名称已从 更改path为myPath。PATH 是一个保留的系统变量，不应用于除预期用途之外的任何其他用途。

A search/replace isn't even needed in such cases. Just strip the original quotes from your argument (with %~1) - then you can add again whatever you want, e.g. the escaped quotes. In your example:
在这种情况下甚至不需要搜索/替换。只需从您的参数中删除原始引号（使用%~1） - 然后您可以再次添加任何您想要的内容，例如转义引号。在你的例子中：
runas /user:abc "icacls \"%~1\" /grant Everyone:(F) /T"
