backup.tar is an uncompressed tar archive. Using GNU tar, list its members without extracting any files.

$ ls
backup.tar
How do you list the archive’s contents?
Fixed. By hand.
tar -tf backup.tartar -t lists archive members and -f selects the archive file. Extraction uses -x; keep listing and extraction distinct when reviewing an archive.
