Use the -BACKUP option.

By adding the -BACKUP (or -b in simplified notation) option to the command, you protect yourself against an unexpected event independent of Distro Tracker : the inaccessibility of the website of one of the distributions from which you wanted to retrieve information.

Option mechanism.

Depending on the chosen output file name, either customized or date-based, the script will test and find the most recently preserved old data and restore it in your new output file.

Data processing.

Due to the source field present in all output file formats, the script notifies you whether the data is new (current) or from previous data (archive).

This way, you can always and under all circumstances create your data file !

Happy tracking !
