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

Copy a file using pv and watch its progress

pv allows a user to see the progress of data through a pipeline, by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA. (man pv)

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
rsync --progress file1 file2
dd if=fromfile of=tofile & DDPID=$! ; sleep 1 ; while kill -USR1 $DDPID ; do sleep 5; done

This is a more accurate way to watch the progress of a dd process. The $DDPID=$! is needed so that you don't get the PID of the sleep. The sleep 1 is needed because in my testing at least, if you run kill -USR1 against dd too quickly, it will kill it off instead of display the status. So you need to wait a second, probably so that it can configure itself to trap the USR1 signal.

dd if=/dev/sdc of=/dev/sdd conv=notrunc & while killall -USR1 dd; do sleep 5; done

The following command will clone usb stick inside /dev/sdc to /dev/sdd

Double check you got the correct usb sticks (origional-clone)with fdisk -l.

dc3dd progress=on bs=512 count=2048 if=/dev/zero of=/dev/null
gcp [source] [destination]

Know a better way?

If you can do better, submit your command here.

What others think

how can you copy folders using pv command?

Comment by pranavkaranjkar 299 weeks ago

It's easy with rsync:

rsync --progress -av Downloads /media/glaudiston/Seagate\ Expansion\ Drive/test/

But we can archive(uncompressed) the folder then send it with pv:

~$ SRC="/source/folder"; TRG="/target/folder/"; tar cf - "$SRC" | pv -s $(du -sb "$SRC" | cut -f1) | tar xf - -C "$TRG"
