“Hello Carl” -replace “Carl”, “Eddie” Hello Eddie -replace操作符有三种实现方式,其它文本操作符也类似地有三种实现方式,像-replace,-ireplace,-creplace,i前缀表示字符串大小写不敏感(insensitive),c前缀表示字符串大小写敏感(case sensitive)。 #下面的例子没有完成替换,因为当前大小写敏感: “Hello Carl...

-replace 运算符允许使用右操作数指定的值替换左操作数指定的一个或多个字符串中的文本。 此运算符有两个变体(§7.8)。 右操作数具有以下形式之一:要定位的字符串,它可能包含正则表达式(§3.16)。 在这种情况下,替换字符串为隐式“”。 包含两个对象的数组,第一个对象为要定位的字符串,后一个对象为替换字符...
By default, the -replace operator is case-insensitive. To make it case sensitive, use -creplace. To make it explicitly case-insensitive, use -ireplace. Examples: PowerShell Copy "book" -ireplace "B", "C" # Case insensitive "book" -creplace "B", "C" # Case-sensitive; hence, nothin...
-ireplace Case-insensitive replace (e.g. "abcde" –ireplace "B","3") -creplace Case-sensitive replace (e.g. "abcde" –creplace "B","3") -and AND (e.g. ($a -ge 5 -AND $a -le 15) ) -or OR (e.g. ($a –eq "A" –OR $a –eq "B") ) -is IS type (e.g. $...
PowerShell is also case-insensitive. Using the built-in gps alias (which represents the Get-Process cmdlet) along with parameter shortening, you can instead type: PS > gps -n lsass Going even further, PowerShell supports positional parameters on cmdlets. Positional parameters let you provide ...
default, Select-String does case-insensitive matching; that means the letter case is ignored which, in turn, means that bothFAILUREandfailurewill be tagged as matches. If you’d prefer to perform a case-sensitive match, in whichFAILUREandfailuredonotmatch, then simply add the–caseSensitive...
中的正则表达式用于匹配文本的模式,它可以由文本字符、运算符和其他构造组成。 以下是一些常见的正则表达式示例和用法: 字符文本:直接匹配指定的文本字符串。例如,'book'-match'oo'会返回True,因为book中包含字符串oo。 字符类:使用特定的字符类来匹配一类字符。例如,\d匹配任何十进制数字,\w匹配任何单词字符(包括字...
Well, that depends on whether you do a case-sensitive comparison (where an uppercase S is considered a different character than a lowercase s) or a case-insensitivecomparison, where S and s are considered the same character. The CompareTo method always does a case-insensitive comparison. To ...
