Example 1:

for /F "tokens=3 delims= " %%A in ('manage-bde -status %systemdrive% ^| findstr "    Encryption Method:"') do (
    if "%%A"=="AES" goto EncryptionCompleted
)
:EncryptionCompleted

Example 2:

for /F %%A in ('wmic /namespace:\\root\cimv2\security\microsofttpm path win32_tpm get IsEnabled_InitialValue ^| findstr "TRUE"') do (
    if "%%A"=="TRUE" goto nextcheck
)
:nextcheck

Please help to find the below code as run on .bat to stop script execution.

The command is:

powershell.exe (Get-Tpm | Select -Property TpmReady).TpmReady -eq $False

then goto Failed
:Failed

CodePudding user response：

• Since you're only looking to act on a Boolean value, you can communicate that via the PowerShell process' exit code, with 0 corresponding to $true and 1 to $false, given that the widely observed convention is that exit code 0 signals success, whereas any nonzero exit code signals an error condition.

  • Boolean values in PowerShell can directly be converted to integers, which, however, performs the opposite mapping: [int] $true is 1 and [int] $false is 0.
  • Therefore, the logic must be reversed with -not before passing the Boolean to PowerShell's exit statement.

• On the cmd.exe (batch-file) side, this allows you to act on the exit code with the || operator, which only executes the RHS in case of failure, i.e. if the LHS command reported a nonzero exit code (such as 1).

powershell.exe -noprofile -c "exit -not (Get-Tpm).TpmReady" || goto :FAILED

echo "TPM is ready."
exit /b 0

:FAILED

echo "TPM is NOT ready." >&2
exit /b 1

^{Note that I've added the following CLI parameters to the PowerShell call: -noprofile to potentially speed up execution, and -c (-Command) to explicitly signal that a command (piece of PowerShell code) is being passed.}
