问题描述
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'
推荐答案
您可以使用格式并将其分配给另一个变量:
You can use formatting and assign it to another variable:
$pw = "$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:
Or you can use double quotes and escape the inside quotes with quotes:
$pw = "$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:
Or do the same but use backtick (grave) to escape them:
$pw = "$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"
