backup data with tar and show them

Hey everyone,
i just want to backup data with tar. I know it works with:
tar cvf. To show which data i have saved i can use tar tvf. But how can i do it simoultanous, that unix not first has to save my data to disk and after that read the data again to show me the list of my saved data?
Please help!!!!

Hi

If you use `tar -cvf .....`, the -v option means tar is running in the verbose mode.
when redirect standard output to a file, you have the list of files in your tar archive.

The long way:

tar cf <usual stuff> && tar tvf <usual stuff>

replace <usual stuff> with required data, eg. filename, folder, etc!
