Utility commands for troubleshooting
After executing a utility command, a value is returned into the ERRORLEVEL environment variable indicating the success or failure of the execution. The ERRORLEVEL variable is a Windows™ environment variable that contains the return code of the last DOS command you executed.
To retrieve the value of the ERRORLEVEL variable, run the following DOS command.
ECHO % ERRORLEVEL %
Utility commands return the following valid values in the ERRORLEVEL variable:
- Return Code
- Description
- 0
- This value indicates that the utility command was successful.
- 1
- This value indicates that the utility command was not successful.
The ERRORLEVEL variable can also be used in batch files to retrieve the value of the return code.
