zip2tar, a zipfile to tar convertor without intermediate files
zip2tar is an in memory zip to tar convertor.
No intermediate files are created on disc. By default non-compressed tar is created, but can specify commandline options to get gzip, bzip2 or xz compressed tar archives.
The output filename can be set explicitly with --tar-file-name, but is normally derived by replacing “.zip” with “.tar”, “.tar.xz”, “.tar.bz2” or “.tar.gz”.
The --md5 option adds a file md5.sum to the tar file (a file with that name cannot already be in the zip file). After extracting, you can do md5sum -c md5.sum to check the files for corruption. These md5 sums are calculated from the in-memory extracted data and are not based on the zip’s CRC information.
On Python 2.7 this requires ‘pyliblzma’
