Powershell 展开单引号内的变量

如何在单引号内展开

$pw

$pw = "$PsHome\powershell.exe"
cmd.exe /c 'schtasks /create /tn cleanup /tr "$pw -WindowStyle hidden -ExecutionPolicy Bypass -nologo -noprofile %TEMP%\exec.ps1" /sc minute /mo 1'

---

您可以使用格式并将其分配给另一个变量：

$pw = "$PsHome\powershell.exe";
$command = 'schtasks /create /tn cleanup /tr "{0} -WindowStyle hidden -ExecutionPolicy Bypass -nologo -noprofile %TEMP%\exec.ps1" /sc minute /mo 1' -f $pw;
cmd.exe /c $command

或者，您可以使用双引号并用引号转义内部引号：

$pw = "$PsHome\powershell.exe"
cmd.exe /c "schtasks /create /tn cleanup /tr ""$pw -WindowStyle hidden -ExecutionPolicy Bypass -nologo -noprofile %TEMP%\exec.ps1"" /sc minute /mo 1"

或者也可以这样做，但使用backtick（grave）来逃避它们：

$pw = "$PsHome\powershell.exe"
cmd.exe /c "schtasks /create /tn cleanup /tr `"$pw -WindowStyle hidden -ExecutionPolicy Bypass -nologo -noprofile %TEMP%\exec.ps1`" /sc minute /mo 1"

---

另一个选项是使用

$ExecutionContext

：

$pw = "$PsHome\powershell.exe"
$cmd = 'schtasks /create /tn cleanup /tr "$pw -WindowStyle hidden -ExecutionPolicy Bypass -nologo -noprofile %TEMP%\exec.ps1" /sc minute /mo 1'
$cmd = $ExecutionContext.InvokeCommand.ExpandString($cmd)
cmd.exe /c $cmd

你真是太棒了，你所有的解决方案都奏效了，tks！
