Bad advice in the README.md

cparke2 commented 8 years ago

This is a great utility you've created that is working well for me on Mac OS X. However, when rebuilding the archive, you advised in the readme file to use "tar tf backup.tar | grep -F "com.package.name" >package.list" to store off the original order of the files to be used subsequently with "tar cf restore.tar -T package.list" when creating the new tar file to pack,

There is a big problem with this suggestion: tar includes subdirectory names as well as files in the package.list file! When you go to recreate the tar using that list file, all the files in the subdirectories get added multiple times! (once for the directory listings, and again for the file listings). Talk about bloat! Not to mention the exact file ordering is not preserved for the subdirectories because they are added for the subdirectory listing first. There isn't an easy way to fix this, the subdirectories need to be filtered out of the package.list somehow and tar doesn't provide such an option, for now I'm using a bash shell script to repair the list.
