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.

dd with progress bar

piping through 'pv' shows a simple progress/speed bar for dd. This is a replacement for my otherwise favorite 'while :;do killall -USR1 dd;sleep 1;done'

What others think

Is the pv command system specific? I've checked a bunch of my machines and have not found it.

What system was this tested on?

Cheers,

Comment by oernii2 202 weeks and 5 days ago

A slight improvement on the above which will show a more useful progress bar by specifying the size parameter to pv:

% dd if=input_file | pv -s `du -bc input_file | cut -f 1 --output-delimiter=" " | head -1` | dd of=output_file

A simpler way

pv -tpreb input_file | dd of=output_file
