I’ve also used dd if=filename | ssh hostname dd of=remote_filename Quite a bit

  There's something a little badass about using dd to transfer a file to a remote system.

    Everything is a file!

    I was transferring files to an Android device, and adb push wasn't working for some reason. It would hit an error and kill the adb connection until I re-plugged the USB. Somehow this worked: dd if=foo | adb shell dd of=/storage/.../foo

  Huh, pleasantly surprised to learn that dd correctly handles the truncated final block of a not-multiple-of-512-byte file; could have sworn that didn't work at some point.

    SUS specifies that dd should do the "right thing" with input with non-integer number of blocks input, that is pad it with zeros if conv=sync, just pass through shorter otherwise.

      > SUS specifies that dd should do the "right thing" A example the C standard could stand to learn from, then.

  Ah yes, that one too. Used it a couple of times straight with a /dev/sda to best effort salvage data from a broken but running remote system I knew would not reboot as is.

  Why not just cat file | ssh user@host 'cat >file' ssh user@host cat file | cat >file ? PS. I use mc to copy: F5, Enter.

    Cause when I younger I didn’t know how to pipe like that and dd just worked. It’s kinda stuck with me and there isn’t much a different imo
