har -t archive-name [object-file...]
To show the members which comprise an archive, you use the -t switch. The member's names are listed together with their sizes. If you only give the archive name on the command line, the archiver lists all the members contained in the archive. However, you can list the attributes of specific members of the archive by specifying on the command line the names of the members youre interested in.
To list all the members of the archive cclib.hza created above you'd use:
har -t cclib.hza
To list only the attributes of the member ir.hzo contained in the archive cclib.hza youd use:
har -t cclib.hza ir.hzo
