\n\tUndocumented command options … grrr!\n<\/p>\n
\n\tEvery so often I find that I have a need to put a volume label onto a FAT filesystem – usually so a digital camera SD (or CF) card can be "automatically" mounted (actually they don't mount automatically on my workstation and I like it like that) in the right place. And of course every time I do, I remember that the command to do so is mlabel<\/em> but I cannot remember exactly how to do it.\n<\/p>\n \n\tBecause mlabel<\/em> (together with the other mtools<\/em>) has some sort of weird configuration file to turn Unix\/Linux paths into drive letters\u203d<\/em> And yes that was an interribang although it could just as well be some other form of punctuation to express disgust instead. As it happens mlabel<\/em> has an undocumented option to specify a device path … at least it doesn't appear in the usage hints :-\n<\/p>\n \n\tIt turns out that there is a "-i" option which takes a device path, but you still have to specify the drive as "::" just so things are less likely to go right :-\n<\/p>\n \n\tAnd there it is!<\/p>\n","protected":false},"excerpt":{"rendered":" Undocumented command options … grrr!
