Tue 02 Jun 2020 06:41:49 PM UTC, original submission:  

I accidentally ran the same command twice:
tar --remove-files -cf ../2019-09.tar 2019-09-

The second invocation replaced the tar file containing my data with an empty one, even though it died with the error messages:
tar: 2019-09-: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

It would be nice if tar did not create a new tar file until it actually had something to write to it, but I imagine that change would break some existing scripts.

Perhaps if there was a command-line option I could pass to tar via bashrc to get a warning before overwriting existing files in the future (similar to "alias mv='mv -i'").

Thank you.
