Description Ivan Sorokin 2023-09-21 13:12:34 UTC
Hello!

I am working on FISH (https://en.wikipedia.org/wiki/Files_transferred_over_shell_protocol) protocol implementation for Far Manager Linux port (https://github.com/elfmz/far2l/issues/1819).

For the protocol to work reliably, support for the "fullblock" option of the dd command is necessary, as it is done in GNU dd. If this is possible, please add support for this option. Thank you!

According to the changelog, dd iflag=fullblock was introduced into busybox relatively long ago:

1 July 2018 -- BusyBox 1.29.0 (unstable)
