Make lsblk list devices by-id
I’m constantly having the situation where I want to correlate the output of lsblk which prints devices in a tree with their name in the scheme of /dev/sdXY with the drives /dev/disk/by-id/ names.
The by-id names consists of the drive model together with the serial something which lsblk can be instructed to list:
lsblk -o name,model,serial
The output of this command will look something like this:
NAME MODEL SERIAL
sda SAMSUNG HD203WI S1UYJ1VZ500792
├─sda1
└─sda9
sdb ST500DM002-1BD14 W2APGFP8
├─sdb1
└─sdb9
sdc ST500DM002-1BD14 W2APGFS0
├─sdc1
└─sdc9
For posterity here’s also a longer command with some commonly used columns:
sudo lsblk -o name,size,fstype,label,model,serial,mountpoint
The output of which could be:
NAME SIZE FSTYPE LABEL MODEL SERIAL MOUNTPOINT
sda 1,8T zfs_member SAMSUNG HD203WI S1UYJ1VZ500792
├─sda1 1,8T zfs_member storage /home
└─sda9 8M zfs_member
sdb 465,8G btrfs ST500DM002-1BD14 W2APGFP8
├─sdb1 465,8G btrfs
└─sdb9 8M btrfs
sdc 465,8G btrfs ST500DM002-1BD14 W2APGFS0
├─sdc1 465,8G btrfs rpool /
└─sdc9 8M btrfs
As found here, the device ids can be seen by ls -l /dev/disk/by-id.
So, Your task could be accomplished e.g. by something like:
lsblk |awk 'NR==1{print $0" DEVICE-ID(S)"}NR>1{dev=$1;gsub("[^[:alnum:]]","",dev);printf $0"tt";system("find /dev/disk/by-id -lname "*"dev"" -printf " %p"");print "";}'
or
lsblk -r|awk 'NR==1{print $0" DEVICE-ID(S)"}NR>1{dev=$1;printf $0" ";system("find /dev/disk/by-id -lname "*"dev"" -printf " %p"");print "";}'
