Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Watch the progress of 'dd'

Terminal - Watch the progress of 'dd'
dd if=/dev/urandom of=file.img bs=4KB& sleep 1 && pid=`pidof dd`; while [[ -d /proc/$pid ]]; do kill -USR1 $pid && sleep 10 && clear; done

Watch the progress of 'dd'

The previously-posted one-liner didn't work for me for whatever reason, so I ended up doing this instead.

Watch the progress of 'dd'

Running this code will execute dd in the background, and you'll grab the process ID with '$!' and assign it to the 'pid' variable. Now, you can watch the progress with the following:

while true; do kill -USR1 $pid && sleep 1 && clear; done

The important thing to grasp here isn't the filename or location of your input or output, or even the block size for that matter, but the fact that you can keep an eye on 'dd' as it's running to see where you are at during its execution.

Only slightly different than previous commands. The benefit is that your "watch" should die when the dd command has completed. (Of course this would depend on /proc being available)

run this in another terminal, were xxxx is the process ID of the running dd process.

the progress will report on the original terminal that you ran dd on
