-match 運算符會使用正則表達式來執行比對。 PowerShell 複製 'PowerShell' -match '^.*shell$' Output 複製 True 使用範圍運算子,將數位 1 到 10 儲存在變數中。 PowerShell 複製 $Numbers = 1..10 判斷$Numbers 變數是否包含15。 PowerShell 複製 $Numbers -contains 15 Output 複製 Fal...
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" echo "sysmon64" | grep -P '^s.{5}\d{2}' windows P...

The caret ^ matches the start of a string, and $, which matches the end of a string. The anchors allow you to match your text at a specific position while also discarding unwanted characters. PowerShell Copy # The pattern expects the string 'fish' to be the only thing on the line....
Use comparison operators (-eq,-ne,-gt,-lt,-le,-ge) to compare values and test conditions. For example, you can compare two string values to determine whether they're equal. The comparison operators also include operators that find or replace patterns in text. The (-match,-notmatch,-repla...
