Listing the content of a tar file or a directory only down to some level

Question

I wonder how to list the content of a tar file only down to some level?

I understand tar tvf mytar.tar will list all files, but sometimes I would like

Answer 1

It would be nice if we could tell the find command to look inside a tar file, but I doubt that is possible.

I quick and ugly (and not foolproof) way would be to limit the number of directory separators, for example:

 $ tar tvf myfile.tar | grep -E '^[^/]*(/[^/]*){1,2}$'

The 2 tells to display not more than 2 slashes (in my case one is already generated by the user/group separator), and hence, to display files at depth at most one. You might want to try with different numbers in place of the 2.
