List top ten files/directories sorted by size

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?

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'
