为了提取对象的方法和属性细节,我们需要利用管道将输出对象定向到 Get-Member CmdLet。管道在大多数命令行和 shell 环境中的操作是相似的。然而,在 PowerShell 中,它们是特定于对象和上下文的。 在本例中,我们希望查询的 CmdLet Get-Service 没有执行,而是将对象信息传递给 Get-Member CmdLet,如图 1-16 所示。注意...

This method splits the $string where it finds the first occurrence of the specified separator (whitespace in this case) and stores the first substring in $var1_string and the second substring in $var2_string variables. Similarly, we can use this method to split $string into multiple variable...
The results of the first ForEach-Object command are piped into a second ForEach-Object command, which displays the current values of $temp and $_. PowerShell Copy # Create a variable named $temp $temp=8 Get-Variable temp # Note that the variable just created isn't available on the #...
-split operator switch statement with -regex option 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...
The-splitoperator also takes a regular expression, so to, say, split on a number, you could do it like this: PS E:\> 'first1second2third3fourth' -split '\d' first second third fourth With Perl, you could do it like this (read more aboutPerl from PowerShell here): ...
how can I split a line with a space and a tab? how can I stop "Select-Object -Property" from truncating the output? How can I suppress an error from Get-WmiObject cmdlet? -ErrorAction SilentlyContinue does not work How can I tell using XP SP3 if a DLL is registered? How can I tri...
Using Split()Method Use the Split() method to trim the string after the first occurrence of the specified character in PowerShell. Use Split() Method 1 2 3 4 5 $string = "Hi! Welcome to Java2Blog! Let's learn." $newString = ($string.Split("!"))[0] Write-Output $newString...
Then the split method breaks the current string at each comma character and stores the results into variables $caseID, $input, and $expected.Windows PowerShell has several error-handling features, including a trap statement to deal with exceptions. For example, in test automati...
