I am extracting a big tarball, but the job was killed in the midway. Is it possible to continue extraction without rolling back from the beginning? The command I was using was
tar xvf foo.tar.gz

Short answer: --skip-old-files
Longer answer: tar --skip-old-files -xvf aoeu.tar will make tar silently ignore any files that has a corresponding output file. It is also possible to use the -k flag, but this will result in tar throwing an error and cowardly refuse to do anything further. However, I am not sure how a partially extracted file will be treated, so you may have to identify those manually and do those individually (if tar was aborted mid-operation, there should be only one not matching in size and content).

1He could do a
--diffor--compareafterwards to check for any corrupted files. – paradroid – 2015-05-15T21:23:07.287This does not seem to work. After adding this option, it gives me an error message of "tar: --keep-old-files: Cannot open: No such file or directory. tar: Error is not recoverable: exiting now. Could it be because of a bug of tar? They seem to have a patch, but it is not pushed to the official release yet?
