The tar utility

[Dennis Handly]

># tar -cvf data-.tar /data
I don't know why, maybe I got misunderstand of syntax

Those were meta chars indicating that you figure out how you want the date. Either manually, or by V. Nyga's variable or you can use $() directly:
tar -cvf data-$(date +%Y%m%d).tar /data

There is no need to wait. You can stop using tar now and switch to pax. They are compatible until you use "-x pax".

Thanks a lot, V and Dennis, and other who gave me advice,suggestions and examples.
I could solve and learn how to work with tar utility.
