Disk usage (du) displays TB not MB

Question

I have an issue while running du that it does not display the usage in units of Megabytes (as expected with -m switch) but TB:

$ du -mhs /mnt/b
2.0T    /mnt/b

How can I get a more granular result?

Answer 1

You need to remove the 'h'. That will convert everything to the most close size format, overwriting the other parameter.

So the proper command would be du -ms /mnt/b

Answer 2

Use the -m option by itself to display the disk usage in 1 Megabyte block units. Note that the disk usage will be displayed as an integer, i.e. only a number without a unit size.

The -h switch "overrides" the -m switch and will display the disk usage not in blocks of any size, but in a human readable format, converting to GB's and TB's as needed. That number will include unit sizes like k, M, G, T
