I believe versions 6.1 - 6.6 were affected. The issue I had was that the second file/dir argument onwards was not properly tallied. So, using your example, jigdo would show a size of 1 if it were run as: >du -smxc yum jigdo but if you changed the command line to: >du -smxc jigdo yum Then jigdo would show the correct size of 48. -BR

In my tests, with or without -x didn't make a difference: >du -smxc yum jigdo 1 yum 48 jigdo 48 total >du -smc yum jigdo 1 yum 48 jigdo 48 total But leaving off the -m, the total is the correct sum of the two directories: >du -sxc yum jigdo 416 yum 48660 jigdo 49076 total I think that du -mc is adding the sizes first, then converting to 1 MiB blocks, therefore showing the approximation error in the total. In the -m case, 416 KiB rounds to 1 MiB, 48660 KiB rounds to 48 MiB, but the total isn't calculated as 1 + 48, but rather as 416 KiB + 48660 KiB = 49076 KiB, 49076 KiB / 1024 = 47.92 MiB, which rounded off becomes 48 MiB.

Pretty sure it's the same thing though. Chuck, If it were rounding error I should still be able to make direct comparisons between the results, as long as they all used the -m argument. Thanks, BR
