However you might tag each command in your batch file with %2 which if <strong>-log=</strong> is present would redirect the output, and if not present, there would be no redirected output:<br/><br/><strong>batchfile.bat</strong><br/> Code: <a>[Select]</a>command1 %2<br/>command2<br/>command3 %2<br/><br/>if you run the batch file as <strong>batchfile -log=">>path to save batch'c log"</strong>, the output from commands 1 and 3 would be redirected. If you run the batch file as <strong>batchfile</strong> with no parameters, then none of the command output would be redirected.<br/><br/> <br/><br/><strong>Note:</strong> This method is not best practice. Readability would be increased if you simply used positional arguments on the command line. Not everyone might recognize that <strong>-log=">>path to save batch'c log" </strong>resolves to two parameters.</p></body></html> | |
