3. PowerShell String类方法 使用String类命令: 之前已经讨论过,对象方法和类方法的区别了,再回顾一次。 String对象衍生自string类在控制台输入[String]::然后按Tab键会自动智能提示,这些方法就是String类命令。 Get-Member会返回所有string对象的方法,可以通过参数只返回静态方法,也就是str
10 -eq "010" # True, int comparison "010" -eq 10 # False, string comparison "RED" -eq "Red" # True, case-insensitive comparison "RED" -ceq "Red" # False, case-sensitive comparison "ab" -lt "abc" # True 10,20,30,20,10 -ne 20 # 10,30,10, Length 3 10,20,30,20,10 -...
<string[]> -like <wildcard-expression> <string[]> -notlike <wildcard-expression> <string[]> -match <regular-expression> <string[]> -notmatch <regular-expression> これらの演算子の入力がスカラー値の場合、ブール値が 返されます。 入力が値のコレクションである場合、コレクション内...
PowerShell regular expressions are case-insensitive by default. Each method shown above has a different way to force case sensitivity. ForSelect-String, use theCaseSensitiveparameter. For operators that use regular expressions, use the case-sensitive version:-cmatch,-creplace, or-csplit ...

要在PowerShell 中使用正则表达式,可以结合相关的命令和操作符。例如,-match操作符用于测试一个字符串是否匹配正则表达式;Select-Stringcmdlet 可在文本中搜索匹配正则表达式的行等。 例如: linux grep grep 指令后跟 “-P" 参数,则表示要使用 “PREs"
A bonus Select-String Tip. By 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...
PS > "Hello World" -match "Hello" True PS > "Hello World" -match 'Hello$' False Bydefault, PowerShell’s comparison operators are case-insensitive. To use the case-sensitive versions, prefix them with the characterc: -ceq,-cne,-cge,-cgt,-cin,-clt,-cle,-clike,-cnotlike,-cmatch,...
<String> -replace <regular-expression>, {<Script-block>} 在脚本块中,使用 $_ 自动变量访问要替换的输入文本和其他有用信息。 此变量的类类型为 System.Text.RegularExpressions.Match。 以下示例将每个三位数字的序列替换为字符等效项。 脚本块针对需要替换的每个三位数字集运行。 PowerShell 复制 "072101108...
-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” -creplace “carl”, “eddie” ...
