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.

Create a bunch of dummy text files

Avoiding a for loop brought this time down to less than 3 seconds on my old machine. And just to be clear, 33554432 = 8192 * 4086.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
for i in `seq 1 4096`; do tr -dc A-Za-z0-9 </dev/urandom | head -c8192 > dummy$i.rnd; done
for i in {1..4096}; do base64 /dev/urandom | head -c 8192 > dummy$i.rnd ; done
1

Using the 'time' command, running this with 'tr' took 28 seconds (and change) each time but using base64 only took 8 seconds (and change). If the file doesn't have to be viewable, pulling straight from urandom with head only took 6 seconds (and change)

Know a better way?

If you can do better, submit your command here.

What others think

Nice. I'd like to enhance the readability:

base64 /dev/urandom | head -c $((8192 * 4096)) | split -b 8192 -da 4 - dummy.

Also, saves the trouble of calculating ahead :-)
