Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

This is becoming a greatest hit on commandlinefu. awk allows use of uninitialized variables, so you could write:

... xargs du -k | awk '{t+=$1} END {print t}'

Further, the job that xargs is doing can be done by find here using the multiple-args-per-invocation -exec option:

find $DIR -type f -name "*txt*" -exec du -k {} + | awk '{t+=$1} END {print t}'

The '{}' is where the filenames are put, and the '+' indicates to run du on many arguments at once. See 'man find' for more.

Looks like the best way to do this is to us the -c option of du to produce a grand total, taking the place of the awk summation part.

Assuming your version of du has a -c option of course (Solaris 10 bundled version doesn't).
