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

What others think

Neat trick, but does this do anything a cp or rsync wouldn't?

Comment by Viaken 398 weeks ago

What's the matter of this, apart from wasting cpu ?

Comment by CodSpirit 398 weeks ago

If wrapped with SSH it's a useful to transfer large directories over a network without any intermediate copying, and faster than scp, such as in:

ssh [email protected] "tar cf - ." | tar xf -

The command as presented is instructive in showing how to use stdin/stdout with tar and subshells.

Comment by bwoodacre 398 weeks ago

Well, if you are in a restricted env. (like a rescue system), it's a poor man sync. One of its advantages is copying _everything_, including special files, links, etc.

And of course, if you are doing this locally, using compression _is_ wasting cpu cycle, but not over a network.

When copying a whole file system, as an exercise for the reader, you usually want to avoid /proc, /tmp, etc..

Comment by pruneau 398 weeks ago

the -f - is not necessary,

tar -c |(cd /new/dir;tar -x) is sufficient
Comment by elzapp 398 weeks ago


tar -c |(cd /new/dir;tar -x)

is sufficient

Comment by elzapp 398 weeks ago

I like this.

The -v option let's you see what's going on.
