Hi all, I would like to have the example of process redirection similar to this one tee -p (head -c1 | wc -c ) > >(head -c10M | wc -c) in the tee's manual page. What do you think about it and what is the process to request it? Thanks a lot Jirka On Sun, Nov 22, 2015 at 9:34 PM, Pádraig Brady

Hi, thanks for the script, it definitely provides more control than the plain tee command. I have done some modifications so that progress can be watched live I have tried two versions of the main command (one with >/dev/full, other one with >&-). cat /dev/zero | head -c500M |
