Troubleshooting Command Line Errors

Troubleshooting Command Line Errors

I ran a DVOCmd command that got an error and used the redirection operator to write the messages to a file. The redirection operator does not redirect all messages to the output file.
When you run a DVOCmd command, the command line utility writes regular messages to the STDOUT output stream and writes error messages to the STDERR output stream. You use the redirection operator to write messages to an output file. To merge messages from both output streams, enter "2>&1" after the output file name.
For example, you encounter an error while refreshing folder "MyFolder" in Data Validation Option repository "DVORepo." To write all messages, including the error messages, to a text file called "Log.txt," use the following command:
DVOCmd RefreshRepository DVORepo --folder MyFolder > C:\Log.txt 2>&1
To append messages to an existing log file called "DVOLog.txt," use the following command:
DVOCmd RefreshRepository DVORepo --folder MyFolder >> C:\DVOLog.txt 2>&1
