在PowerShell 中使用錨點時,您應該瞭解 Singleline 與 Multiline 正則表示式選項之間的差異。多行:多行模式會 ^ 強制並 $ 比對每個LINE的開頭端,而不是輸入字串的開頭和結尾。 單行:單行模式會將輸入字串視為 SingleLine。它會強制 . 字元比對每個字元(包括換行符),而不是比對每一個字元,但...
Piping toOut-Stringconverts the formatted output into a single multi-line string object. This means that whenSelect-Stringfinds a match it outputs the whole multiline string. PowerShell PS>$hash= @{ Name ='foo'Category ='bar'}# !! NO output, due to .ToString() conversion$hash|Select-...

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"
功能牛逼，但是没shell好用
