List all hard drives on system (with capacities)... How?
I'd like to write a small program or shell script that simply lists all of the physical hard drives attached to the local system, along with their product identifiers and their respective capacities. The following simple script works well for both PATA/SATA and USB hard drives, but it does not list drive capacities: #!/bin/sh atacontrol list | grep ': ad[0-9]' | sed 's/^.*: //' camcontrol devlist | grep '(da[0-9]' | sed -E 's/^(.*) \((da[0-9]+).*$/\2 \1/' How can I modify the script above in order to get it to print out the respective drive capacities? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Look into fdisk -s Thank you Tim. Silly me! Before I even got your reply, I had already doen a bit more research and I had found what I think may perhaps be an even better answer. I never knew about this utility program called diskinfo, but I just now found it, and it seems to do the trick. There appears to be a small problem with using fdisk -s... It looks like it hiccups when and if the drive in question has not actually been partitioned yet: # fdisk -s /dev/ad6 fdisk: invalid fdisk partition table found (The diskinfo utility apparently does not suffer from this problem.) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Look into fdisk -s I think fdisk should need a valid partition table, or not? diskinfo works nice with all disk-like devices be it a physical disk, a slice, a partition, a swap-backed device etc. Its output is easily parsable using a single line per device and if you use -v you will get the same info in human-readable form.

You know about the exponentiation operator in Perl -- right?
if ($bytes = (1024 ** 4)) {
I don't think typing 1024 four times with * between each pair is really a
helpful form of verbosity.
