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。其中一个特殊字符是某种 ASCII 撇号,我无法用键复制。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。我希望它用普通的撇号替换它,但我不知道这是如何完成的,目前最大的问题是我无法让它“看到”这个奇怪的撇号,它会自动生成我正在修改的文件。非常感谢任何帮助。谢谢 :)
文件中的撇号:'
普通撇号:'
这是我隔离测试的批处理的一部分。
@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
最佳答案
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,应该是结束引号。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 套报价单:
"
“
”
„
'
‘
’
‚
‛
AFAIK,所有这些引号都存在于大多数 Windows ANSI 代码页(1252、1250、1257、1253、1251、1254、1255、1256、1258)中,因此它们可以按字面意思在
ANSI
中使用-保存.bat
脚本 - 除了后一个引号‛
U+201B
单高反9引号 .在这种情况下,请使用 $([char]0x201B)
而不是 '‛‛'
如下:rem cast [char] to `[string]` ↓↓↓↓↓↓↓↓
powershell -c "(gc '%fileIn%').Replace( [string]$([char]0x201B) , '')"
rem ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
或如下:
rem [char] can't be empty so specify `[string]` ↓↓↓↓↓↓↓↓
powershell -c "(gc '%fileIn%').Replace( $([char]0x201B) , [string]'')"
rem ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
