Watch the progress of 'dd'

The 'dd' command doesn't provide a progress when writing data. So, sending the "USR1" signal to the process will spit out its progress as it writes data. This command is superior to others on the site, as it doesn't require you to previously know the PID of the dd command. Show Sample Output

Start dd and show progress every X seconds

Adjust "sleep X" to your needs. *NOTE: First sleep is required because bash doesn't have a "post-test" syntax (do XXX while). Show Sample Output

dd if=/path/to/inputfile of=/path/to/outputfile & pid=$! && sleep X && while kill -USR1 $pid; do sleep X; done

What Others Think

as cool as this is, it relies on a utility that isn't standard across platforms, and isn't installed by default on any system.
