Alternativa per dd

Descrizione

Funziona esattamente come dd, ma, in più, mostra ogni 3 secondi la quantità di dati trasferiti. Salvare lo script in /usr/local/bin, dargli i permessi di esecuzione con chmod ed usarlo al posto di dd, così:

ddprogress if=/dev/sdc1 of=./backup ...

Script

#!/bin/sh
# ddprogress - show dd progress every 3 seconds
