dd supports a 'status' flag, which enables it to show the copied bytes,
duration, and the transfer rate, which then get printed to stderr.
can you post an excerpt of what it looks like and how frequent it outputs?
Currently, the output looks as following:
2022-11-14 12:01:00 236978176 bytes (237 MB, 226 MiB) copied, 1 s,
237 MB/s
2022-11-14 12:01:01 596377600 bytes (596 MB, 569 MiB) copied, 2 s,
298 MB/s
2022-11-14 12:01:02 947388416 bytes (947 MB, 904 MiB) copied, 3 s,
316 MB/s
2022-11-14 12:01:03 1308295168 bytes (1.3 GB, 1.2 GiB) copied, 4 s,
327 MB/s
2022-11-14 12:01:04 1673527296 bytes (1.7 GB, 1.6 GiB) copied, 5 s,

as unlike a TTY it cannot tell the console to override existing lines, so I
guess this will do some periodic printing?
Yes, as of right now, it prints a new line every second. Maybe one
option to make it "prettier"
would be to limit the lines printed (by, say, only printing every nth
line/second), which should
be rather simple to implement by matching the dd output in Storage.pm,
where log lines are
already being parsed [1].
