We have discussed already what a switch case, its syntax is. Now, we will see in detail how it will work in shell scripting. Initially, we initialize a variable with an expression or value and conditional statement checks whether it satisfies any condition, if yes then it will execute the ...
In this example, the switch statement is testing for the type of the value in the hashtable. You must use and expression that returns a boolean value to select the scriptblock to execute. PowerShell Copy $var = @{A = 10; B = 'abc'} foreach ($key in $var.Keys) { switch ($va...
casevalueN: statementsN// 当表达式的结果等于 valueN 时,则执行该代码 break; default: statements// 如果没有与表达式相同的值,则执行该代码 } switch 语句根据表达式的值,依次与 case 子句中的值进行比较: 如果两者相等,则执行其后的语句段,当遇到 break 关键字时则跳出整个 switch 语句。 如果不相等,则继...
-Regex引數允許 switch 語句根據條件執行正規表示式匹配。 例: switch -Regex ('Condition') { 'Con\D+ion' {'One or more non-digits'} 'Conditio*$' {'Zero or more "o"'} 'C.ndition' {'Any single char.'} '^C\w+ition$' {'Anchors and one or more word chars.'} 'Test...
conditional blocks that allow you to specify a logic in your script, based on a condition (or a set of them). The difference between them is that the switch (at its basic level) evaluates a variable against a set of possible values, although in PowerShell the switch statement is beefed ...
You can use script blocks, for example: switch ("Cozumel") { {$_ -in @("Acapulco","Cozumel","Lazaro Cardenas","Mexico City","Pto Progresso","Veracruz")} { "Mexico" break } } Refer to the documentation for more info/examples:https://docs.microsoft.com/en-us/powershel...
The following example demonstrates the use of script blocks asswitchstatement conditions. PowerShell switch("Test") { {$_-is[string] } {"Found a string"}"Test"{"This$_executes as well"} } Output Found a string This Test executes as well ...
