What others think

This command is really helpful, but it can be really slow with large directories. Also... this warning appears on this find part of the command..

find: warning: you have specified the -maxdepth option after a non-option argument -type, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it). Please specify options before other arguments.

If you put -type d after the depth options it resolves this warning.

Also, it doesn't seem to handle directories with spaces. Maybe..

watch 'find -maxdepth 1 -mindepth 1 -type d | xargs -i du -csh {}'

Comment by mitzip 235 weeks and 6 days ago

I had the same error as you mitzip. To fix, move -type d after the -mindepth -maxdepth arguments. As for your second command, it is not a good idea to have directories or files with spaces. As you can see, it causes problems. It is best use either periods or underscores to represent a space

Thanks,

I've now corrected the arguments to find, the error was hidden (by watch?) when I tried it.

mitzip, thanks for the suggestion on dealing with spaces, but I got a subtotal per line when I tried it. I suppose you could switch subtotals off though

watch 'find -maxdepth 1 -mindepth 1 -type d |xargs -i du -sh {}'
