powershell - 在单引号内扩展变量

Question

如何在单引号内扩展$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'

Answer 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将引号内的引号引起来:

$pw = "$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"

或执行相同操作，但使用反引号(grave)使其逃脱:

$pw = "$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"
