Dd notes
From Zanecorpwiki
Tracking Progress[1]
dd can take a very long time to run, but strangely does not report progress (by default or via any options). It is possible to query the progress with:
kill -USR1 `pgrep -l '^dd$' | awk '{print $1}'`
use watch to get regular updates:
watch -n 20 kill -USR1 `pgrep -l '^dd$' | awk '{print $1}'`
Note that if executing dd remotely, the progress will print on the initiating host, not on the host where the kill is executed.
