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

List top ten files/directories sorted by size

Terminal - List top ten files/directories sorted by size
du -s * | sort -nr | head | cut -f2 | parallel -k du -sh

If a directory name contains space xargs will do the wrong thing. Parallel https://savannah.nongnu.org/projects/parallel/ deals better with that.


There are 2 alternatives - vote for the best!

Terminal - Alternatives
du -sb *|sort -nr|head|awk '{print $2}'|xargs du -sh

Know a better way?

If you can do better, submit your command here.

What others think

That is, xargs does the "wrong thing" by default, but you can tell it to use any delimiter to separate arguments with the --delimeter option, such as a newline. xargs can also launch jobs in parallel with the -P option. It's good to know about the parallel command though, it's a perl script; I can't find it in Debian/Ubuntu though.

xargs has several race conditions if you use -P:

xargs will not guarantee you output with the biggest directory first. It will instead first output the job that finishes first. This is likely to be a problem here.

xargs may mix output, so output lines of jobs printing simultaneously can be mixed. This is not likely to be a problem here.

The solution using parallel prevents these two problems.

@bwoodacre: I have tried to think a way to fixup the xargs solution for the following dir. Can you fix it up?

mkdir '12" records'
