Re: get the size of a special device (drive)

How much OS-independence do you need?

Since you're probably on linux, parsing the output of df or df -h would be very easy. Maybe look at /sys/block/*drivename*/size

I don't think this can be solved completely OS-independently, but I'd be interested in something that worked better on all/most POSIX systems

/sys/block/drivename/size is useful, it looks liek it uses 512k block size?	[reply]

I have no idea. It looked interesting, but I can't seem to find any real info on what the numbers in /sys/block//size mean at all. Personally, I'd go with `du -h` or `du -B 1` (for bytes) "What should it profit a man, if he should win a flame war, yet lose his cool?"*	[reply] [d/l] [select]

Personally, I'd go with `du -h` or `du -B 1` (for bytes) But AFAICT du is for mounted filesystems. He was asking about raw devices. I suppose the answer is somewhere in the docs for sysfs. (The kernel's?)	[reply] [d/l] [select]

unfortunately du requires the filesystem to be mounted, not an option in this case :-(	[reply]
