====== View Progress of dd Command ====== dd is a very useful, and also dangerous, command that allows to copy a whole device to another or to an iso file. It's syntax is as simple as: <code> > dd if=/dev/sr0 of=/path/to/copy.iso </code> Unfortunately there is no progress indication and thus, as it often implies moving a huge amount of data, we're left kind of blind once the command is started. To have a peek at the current advancement of the dd command, one can use the following, from a concurrent terminal of course: <code> > watch -n 10 "kill -USR1 $(pgrep -l '^dd$')" </code> This will output the current dd statistics, in the terminal executing the dd command.
