In the example you provided,$sis a string, not a collection of objects. Therefore, the-containsoperator will not work as expected. Instead, you can use the-matchoperator with a regular expression to check if the string contains a space. For example, if you want to check if the string “...
複製 <string[]> -like <wildcard-expression> <string[]> -notlike <wildcard-expression> <string[]> -match <regular-expression> <string[]> -notmatch <regular-expression> 當這些運算子的輸入是純量值時,它們會傳回
使用正则表达式(regex)和-replace运算符,可以使用捕获的文本动态替换文本。 -replace <original>, <substitute> :要搜索的字符串 <original>:用于搜索输入字符串的正则表达式 <substitute>:一个正则表达式替换表达式,用于替换输入字符串中找到的匹配项。 <original>和<substitute>操作数受正则表达式引擎规则(如字符转义...
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"
-Join<String[]> The second way to use the-Joinoperator is to specify the delimiter to be used. The array of strings will be joined together, but the specified delimiter character will be inserted in between each string. <String[]>-Join<Delimiter> ...
$string=$string.Remove($index,1).Insert($index,'=') } 方法2:(使用正则替换,注意使用分组引用,使用单引号而不应该使用双引号) $string-replace"(^.*?) ",'$1=' #或 $string-replace"^(.*?)\s(.*)",'$1=$2' #或全部用单引号
$string = "This is a sample string" $Array = $string -Split " " $Array OUTPUT 1 2 3 4 5 6 7 This is a sample string For the above code, we used the -Split operator to split the whole $string based on the specified separator (delimiter). We can also substitute -cSplit or ...
