I have found the question How to determine if data is valid tar file without a file?, but I was wondering: is there a ready made command line solution?
What about just getting a listing of the tarball and throw away the output, rather than decompressing the file?
Edited as per comment. Thanks zrajm!
Edit as per comment. Thanks Frozen Flame! This test in no way implies integrity of the data. Because it was designed as a tape archival utility most implementations of tar will allow multiple copies of the same file!
