How to see read and write data stream?

[hack3rcon]

Hello,
When I use "dd" command and forgot to use "pv" or "status=progress" parameter, then how can I see the status? Any command to see read and write stream?

Thank you.

However you do it, it slows you down. You could use an external timer of some kind?
I do many dd like, not dd, operations spawned from a Thunar custom actions and usually put up a generic zenity dialog that states 'working on it'. They all lie, or slow you down! A funnier and more irritating reality is once you mix in hardware specifics the software often says 'done' even tho the drive is still working on it. Write out gigs to a 'smr' drive and you'll see what I mean!

RTFM...

$ man dd
->

Sending a USR1 signal to a running 'dd' process makes it print I/O statistics to standard error and then resume copying.

But why would one care to read the manual..

For the OP:

Code: Select all

# pkill -usr1 -x dd
