有没有一种方法可以在ripgrep中为MS Windows(Powershell或CMD)转义引号? [英] Is there a way to escape quotes in ripgrep for MS Windows (Powershell or CMD)?
问题描述
我想使用 ripgrep
在文本文件中找到字符串"Hello
(Hello以双引号开头).
I want to find a string "Hello
(Hello starts with double quote) in text files using ripgrep
.
通常,在Bash或ZSH中,这可以通过使用反斜杠转义或使用单引号引起来:
Normally, in Bash or ZSH, this would work by escaping with backslash or surrounding with single quote:
rg \"Hello
rg '"Hello'
但是,在MS Windows(Powershell和CMD)中,我已经尝试了这些,但是这些都不起作用:
However, in MS Windows (Powershell and CMD), I've tried these but none of these worked:
rg \"Hello
rg '"Hello'
rg `"Hello
rg '`"Hello'
在MS Windows中,有什么方法可以使用ripgrep来对单引号或双引号进行转义吗?
Is there any way to escape single or double quotes using ripgrep in MS Windows?
推荐答案
逐字字符串"Hello
最终必须作为 \" Hello
传递给 rg
("\" Hello"
也可以).即,逐字记录"
char.必须 \
-转义:
Verbatim string "Hello
must ultimately be passed as \"Hello
to rg
("\"Hello"
would work too). That is, the verbatim "
char. must be \
-escaped:
来自 cmd.exe
:
From cmd.exe
:
rg \^"Hello
^
, cmd.exe
的转义字符,确保对"
进行逐字处理并由 cmd删除.exe
,然后再调用 rg
.
请注意,这里并非强制使用 ^
,但可以防止将"
视为双引号参数的开头,如果有其他参数,则可能会有所不同争论.
^
, cmd.exe
's escape character, ensures that the "
is treated verbatim and is removed by cmd.exe
before calling rg
.
Note that ^
isn't strictly necessary here, but it prevents the "
from being considered the start of a double-quoted argument, which could make a difference if there were additional arguments.
来自 PowerShell :
rg \`"Hello
`
是PowerShell的转义字符,可确保对"
进行逐字处理,并在调用 rg
之前被PowerShell删除.
`
, PowerShell's escape character, ensures that the "
is treated verbatim and is removed by PowerShell before calling rg
.
可以说,不需要显式的 \
转义,因为在用户满意之后,shell的职责是正确地将参数传递给目标可执行文件外壳自身的转义要求(用 cmd.exe
中的 ^
以及在PowerShell中使用`
转义逐字"
).
Arguably, the explicit \
-escaping shouldn't be necessary, because it is the duty of a shell to properly pass arguments to target executables after the user has satisfied the shell's own escaping requirements (escaping the verbatim "
with ^
in cmd.exe
, and with `
in PowerShell).
在PowerShell的上下文中,此答案中总结了这种有问题的行为.
In the context of PowerShell, this problematic behavior is summarized in this answer.
请注意,在PowerShell中,仅当您调用外部程序 时才需要这种额外的转义;不需要PowerShell- 内部-例如当您调用 Select-String
时,如
Note that in PowerShell this extra escaping is only needed if you call external programs; it isn't needed PowerShell-internally - such as when you call Select-String
, as shown in js2010's answer.
