CLI Guide

● Specify the file output using the -o <filename> command, where <filename> is the name of the output file.
Log Files
If the log file already exists, information is appended to the file. This allows multiple tools to use the same log file to record
information. Use the -l option to record the output of a utility.
The log duplicates all standard output and error information to the specified file. Each log file begins with a time stamp and
utility name. For example, YYYY/MM/DD HH:MM:SS < utilname > - <output text> .
The following is an example of the logging behavior:
2003/11/28 10:23:17 syscfg - option1=on
2003/11/28 10:23:17 syscfg - option2=on
2003/11/28 10:23:17 syscfg - option3 =off
NOTE: The log files may contain sensitive information such as passwords and authentication information. To protect such
information, it is recommended that only the administrator accesses the log files.
Help Option
The -h and --help options display general usage information for the utility. If the argument matches a valid option, that usage
information of the option is displayed. If the option has arguments, the arguments are displayed, separated by a | character. If
the argument does not match a valid option, a usage error is given (and usage information is displayed). This option cannot be
replicated.
Error Checking And Error Messages
The DTK utilities check your commands for correct syntax when you enter them. When a command is executed successfully,
a message displays stating that your command has been successful. Unrecognized or invalid options and arguments result in
a usage error that displays the DTK utility name and version along with a short message. For information about the error
messages, see Messages And Codes.
