Cmd 到 powershell 替换 - 特殊字符
Cmd to powershell replace - special character
我正在创建一个脚本，它将复制一个文件，重命名它，然后查看内部以删除某些特殊字符。这些特殊字符之一是我无法用键复制的某种 ASCII 撇号。虽然我可以复制和粘贴它，但是替换功能不起作用。
打开文件 > 搜索奇怪的撇号 ’ 并替换为空。我想用普通的撇号代替它，但我不知道这是怎么做到的，目前最大的问题是我无法将它变成 "see" 这个奇怪的撇号我正在修改的自动生成的文件。非常感谢任何帮助。谢谢:)
文件中的撇号：'
普通撇号：'
这是我分离出来用于测试的批次的一部分。
@echo off
set YYMMDD=%DATE:~-2,2%%DATE:~-7,2%%DATE:~-10,2%
set DDMMYYYY=%DATE:~-10,2%%DATE:~-7,2%%DATE:~-4,4%
set YYYY-MM-DD=%DATE:~-4,4%-%DATE:~-7,2%-%DATE:~-10,2%
powershell -Command "(gc 'C:\LOCATION\Client_List_%DDMMYYYY%.csv') -replace '’', '' | Out-File 'C:\LOCATION\Client_List_%DDMMYYYY%.csv'"
Echo Done
我认为这是一个奇怪的反引号字符。至少它是这样的。
如果我这样做：
$text = "Weird ’ Normal ' Backtick ` Weird ’ "
$text.Replace("’","")
它给了我这个：
Weird Normal ' Backtick Weird
那么这个有用吗？
powershell -Command "(gc 'C:\LOCATION\Client_List_%DDMMYYYY%.csv').replace('’’', '') |
Out-File 'C:\LOCATION\Client_List_%DDMMYYYY%.csv'"
通过加倍一个正常的反引号，它使脚本从字面上理解字符。加倍奇怪的撇号似乎做同样的事情，至少在我的测试中是这样。
set "fileIn=C:\LOCATION\Client_List_%DDMMYYYY%.csv"
set "fileOu=C:\LOCATION\Client_List_%DDMMYYYY%.csv"
powershell -c "(gc '%fileIn%').Replace('‘‘','').Replace('’’','')|Out-File '%fileOu%'"
那个奇怪的撇号’是U+2019右单引号，据说是闭引号。它可以搭配不同的开场白。在上面的例子中，‘是U+2018左单引号.
Get-Help 'about_Quoting_Rules' 说
Quotation marks are used to specify a literal string. You can enclose
a string in single quotation marks (') or double quotation marks
(").
事实上，PowerShell 接受两个不同的 集 引号：
- 双引号
"“”„
- 单引号
'‘’‚‛
AFAIK，大多数 Windows ANSI 代码页（1252、1250、1257、1253、1251、1254、1255、1256、 1258) 所以它们可以在 ANSI-保存的 .bat 脚本中按字面意义使用 - 除了后面的引号 ‛ U+201B Single High -Reversed-9 引号。在这种情况下，使用 $([char]0x201B) 而不是 '‛‛'，如下所示：
rem cast [char] to `[string]` ↓↓↓↓↓↓↓↓
powershell -c "(gc '%fileIn%').Replace( [string]$([char]0x201B) , '')"
rem ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
或如下：
rem [char] can't be empty so specify `[string]` ↓↓↓↓↓↓↓↓
powershell -c "(gc '%fileIn%').Replace( $([char]0x201B) , [string]'')"
rem ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
