Variable names have no interaction between them and the underlying operating system. PowerShell treats them case-insensitively. Module names are case-insensitive (with exceptions) Thenameof the module is purely a PowerShell concept and treated case-insensitively. However, there is a strong mapping...
Get-ChildItem Get-ChildItem e:*.txt | Sort-Object -CaseSensitive | Process-File >results.txt 在第一個案例中,Get-ChildItem 會建立目前/預設目錄中檔案名稱的集合。 該集合會傳送至主機環境,根據預設,會將每個元素的值寫入標準輸出。 在第二個案例中,Get-ChildItem 會使用 自變數 e:*.txt,在指定的目錄...
对于switch语句,请使用-casesensitive选项 字符文本 正则表达式可以是文本字符或字符串。 表达式使引擎与指定的文本完全匹配。 PowerShell # This statement returns true because book contains the string "oo"'book'-match'oo' 字符类 虽然字符文本在知道确切的模式时工作,但字符类允许你不太具体。
用法二如下:switch -casesensitive (表达式)表示区分大小写 $day = "day1" switch -casesensitive($day) # -casesensitive 表示大小写敏感,即区分大小写 { day1 {"It's Monday" ;break} day2 {"It's Tuesday";break} day3 {"It's Wednesday";break} day4 {"It's Thursday";break} day5 {"It's...
switch [-Regex | -Wildcard | -Exact] [-CaseSensitive] -File filename { string | number | variable | { <value-scriptblock> } { <action-scriptblock> } default { <action-scriptblock> } # optional } 如果不使用参数,switch的行为与使用Exact参数的行为相同。 它针对值执行不区分大小写的匹配。
使用區分大小寫的哈希表 Group-Object 搭配 -CaseSensitive 和 -AsHashtable 參數 (#11030) (感謝 @vexx32!) 在重建路徑以具備正確的大小寫時,如果列舉檔案失敗,就會處理例外狀況 (#11014) 修正ConciseView 以顯示 Activity,而不是 myCommand (#11007) ...
Like most (if not all) Windows PowerShell operators, you can also perform case-sensitive checks using the –ccontains and the –cnotcontains operators (the letter c tacked onto the front of each operator stands for “case sensitive”). For example:...
Windows PowerShell reserves a few parameter names, referred to as Common parameters, which you can't use: WhatIf, Confirm, Verbose, Debug, ErrorAction, ErrorVariable, OutVariable, and OutBuffer. In addition, the following aliases for these parameter names are reserved: vb, db, ea, ev, ov...
Sort-Object[-Descending] [-Unique]-Bottom<Int32> [-InputObject <PSObject>] [[-Property] <Object[]>] [-Culture <String>] [-CaseSensitive] [<CommonParameters>] 说明 Sort-Objectcmdlet 根据对象属性值按升序或降序对对象进行排序。 如果命令中不包含排序属性,PowerShell 将使用第一个输入对象的默认排序...
