I need to call .bat file from Powershell script

Question

We are migrating perl script to powershell script. In Perl the code is as shown below

$rc='D:\\EmailConnector\\run.bat> $EmailConnector_log;';

I tried as shown below but not working

StartProcess "cmd.exe" "/c D:\EmailConnector\run.bat> $EmailConnector_log"

When I tried as shown below the .bat script ran, but I want to update the log file. Could you help me on this.

StartProcess run.bat -workingdirectory "D:\EmailConnector"

The .bat file consist of jar file for email functionality. But we want to get log in log file.

I wrote an answer, however, your question is not clear enough, the log file should be the input for the run.bat? or it just need to run from the d:\emailconnector folder? — Avshalom

Use the call operator (&), like this:

& 'D:\EmailConnector\run.bat' > $EmailConnector_log

The return value of the batch script is automatically put into the variable $LastExitCode.

That error comes from the code in your batch file and is unrelated to this question. Please post a new question with the content of the batch file and the error message.

Is that what you mean?

Start-Process "cmd" -ArgumentList '/c','D:\EmailConnector\run.bat' -WorkingDirectory "D:\EmailConnector"

or this one if you need another argument for logfile

Start-Process "cmd" -ArgumentList '/c','D:\EmailConnector\run.bat','EmailConnector_log' -WorkingDirectory "D:\EmailConnector"

Or, since there are no spaces in the path, you can just execute the batch file directly from PowerShell:

D:\EmailConnector\run.bat > $EmailConnector_log

This is one of the advantages of PowerShell being both a "shell" and a "scripting language". Execution of batch, cmd, vbs, exe files is straightforward - usually. Parameter passing can be an issue but these days that is easily solved with the stop parsing operator: --%.
