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 deals better with that.

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'
