This is a border line feature, but I'm 60:40 for implementing it. Note something similar I noticed is: findmnt -l -o FSTYPE,SOURCE,TARGET It would make sense to align as closely to that as possible. So a full --output list supported by df could be FSTYPE,SOURCE,TARGET,SIZE,USED,AVAIL,FREEPCT It's probably sufficient to use this to just order fields, and leave other formatting to existing modifiers. cheers, Pádraig.
