-APPEND mexport option
The -APPEND option can be used with the mexport utility command.
The append (-APPEND) option of the mexport utility command is used to indicate that the current mexport log messages should be appended to the existing mexport log file if it already exists. If the mexport log append (-APPEND) option is selected, the mexport log messages will be appended to the existing file if it already exists; otherwise, a new file will be created. If the (-APPEND) option is not selected, the mexport log file will be created if no log file exists, or it will be overwritten if the log file does exist.
