List information about block devices in the FreeBSD system.
I often need(ed) to work with Linux systems - and there is lsblk(8) command.
Anything closest to it (but still far away) in FreeBSD land are:
# geom disk list
# camcontrol devlist
# gpart show
# mount
# zfs list
... and none of these tools provide complete information like lsblk(8) does.
So I wrote lsblk(8) in POSIX /bin/sh for FreeBSD.
It only supports two modes.
The default one w/o any arguments.
Listing entire disks with -d option.
Hope that helps.
Below you will see examples of lsblk(8) usage.
For comparison - this is how Linux version of lsblk(8) output looks like.
[root@rhidm ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 252:0 0 20G 0 disk
├─vda1 252:1 0 600M 0 part /boot/efi
├─vda2 252:2 0 1G 0 part /boot
└─vda3 252:3 0 18.4G 0 part
├─rhel-root 253:0 0 16.4G 0 lvm /
└─rhel-swap 253:1 0 2G 0 lvm [SWAP]
[root@rhidm ~]# lsblk -d
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 252:0 0 20G 0 disk
... and mine lsblk(8) on FreeBSD system.
