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.

Asked By: Rovanion


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                                       
sdb    ST500DM002-1BD14 W2APGFP8
sdc    ST500DM002-1BD14 W2APGFS0

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

└─sda9     8M zfs_member

└─sdb9     8M btrfs

├─sdc1 465,8G btrfs             rpool                                          /

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 "";}'


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 "";}'
