dd with progress bar

dd if=/dev/nst0 |pv|dd of=restored_file.tar
piping through 'pv' shows a simple progress/speed bar for dd. This is a replacement for my otherwise favorite 'while :;do killall -USR1 dd;sleep 1;done'

What Others Think

Is the pv command system specific? I've checked a bunch of my machines and have not found it. What system was this tested on? Cheers, Mikel King

A slight improvement on the above which will show a more useful progress bar by specifying the size parameter to pv: % dd if=input_file | pv -s `du -bc input_file | cut -f 1 --output-delimiter=" " | head -1` | dd of=output_file

A simpler way pv -tpreb input_file | dd of=output_file
