Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Create a tar archive using 7z compression

Terminal - Create a tar archive using 7z compression
tar cf - /path/to/data | 7z a -si archivename.tar.7z

Create a tar archive using 7z compression

Using 7z to create archives is OK, but when you use tar, you preserve all file-specific information such as ownership, perms, etc. If that's important to you, this is a better way to do it.


There are 6 alternatives - vote for the best!

Terminal - Alternatives
tar -cJf myarchive.tar.xz /path/to/archive/

User: Sepero
Functions: tar

Compress files or a directory to xz format. XZ has superior and faster compression than bzip2 in most cases. XZ is superior to 7zip format because it can save file permissions and other metadata data.

tar -cvf - /path/to/tar/up | xz - > myTarArchive.tar.xz

Functions: tar

compress directory archive with xz compression, if tar doesn't have the -J option (OSX tar doesn't have -J)

Know a better way?

If you can do better, submit your command here.

What others think

some newer versions of tar support the '--lzma' option

LZMA is the same type of compression used by 7zip

This is a cleaner option, though I suppose it is only supported by newer versions of tar which could be a problem...

tar c --lzma /path/to/data > archivename.tar.lzma

According to google, GNU tar supports the lzma option since tar 1.20. Starting in tar 1.22 -J (capital 'j') means --xz and not --lzma.
