List partition labels from the command line

Is there a command that will list all partitions along with their labels? sudo fdisk -l and sudo parted -l don’t show labels by default.

EDIT: (as per comment below) I’m talking about ext2 labels – those that you can set in gparted upon partitioning.

EDIT2: The intent is to list unmounted partitions (so I know which one to mount).

With udev, You can use

ls -l /dev/disk/by-label

to show the symlinks by label to at least some partition device nodes.

Not sure what the logic of inclusion is, possibly the existence of a label.

Try to use mount -l, it work’s fine for me.

This will not list all partitions but you can view and alter what you like with tune2fs.

$ sudo tune2fs -l /dev/sda1

You can use a command such as this to get all the /dev/sda* devices.

$ sudo sh -c 'echo /dev/sda* /dev/mapper/fedora* | xargs -n 1 tune2fs -l'

There is a blkid command which may be what you are looking for. Results are similar to the following:

$ sudo blkid /dev/mapper/vg_rootdisk-lv_var
/dev/mapper/vg_rootdisk-lv_var: LABEL="LV_VAR" UUID="08520908-03cd-4e42-a4e4-0f5a771be16c" TYPE="ext4"

One other option is to use the udevadm command, which likely will give you far more than you need:

$ sudo udevadm info --query=all --name=/dev/mapper/vg_rootdisk-lv_var

Try to use this command:

e2label /dev/sda2

If you like, you can use my bash script for that purpose. It actually does a little more than you need, i. e. it will also show how much space is used.
Hope you like it 🙂
And I also hope that the output will be as neat as on my linux box…
(Note: it will only show real hardware like your HDDs and DVD-ROMs, but that’s sufficient for my purposes.)

Important note: This script might have to be run under sudo ONCE because of blkid. At least on my distro, blkid -o export will output nil when run as regular user after bootup. This is because in the “regular user rendition” of blkid, data will actually be retrieved from a cache file (normally /run/blkid/blkid.tab), which is only writable by root and will thus require one run under sudo in order to get populated with current data.

#!/bin/bash
# LICENSE: GPL

if [[ $(id -u) -ne 0 ]]; then
  if [[ ! -s /run/blkid/blkid.tab ]]; then
   # no cache file found when run as regular user
   # this will require one run under sudo to populate cache file
   echo -e "Cache file does not exist or is empty.nPlease give your root password to continue:nn"   
   sudo blkid >/dev/null

You can also use this command:

$ sudo udevadm info --query all --path /sys/block/sdb/sdb1 
     | grep ID_PART_ENTRY_NAME

You can use the above to print all the block devices’ info.

$ echo /sys/block/* | xargs -n 1 udevadm info --query all --path

/dev/disk

In newer versions of the Linux kernel this info can now be found here under /dev/disk.

Example

$ ls -l /dev/disk
total 0
drwxr-xr-x 2 root root 300 Mar  4 18:43 by-id
drwxr-xr-x 2 root root 140 Mar  4 18:21 by-label
drwxr-xr-x 2 root root  80 Mar  4 18:18 by-path
drwxr-xr-x 2 root root 200 Mar  4  2015 by-uuid

So you can find it by by-id, by-label, by-path or by by-uuid.

  • by-id

    $ ls -l /dev/disk/by-id
    total 0
    lrwxrwxrwx. 1 root root  9 Jan 11 17:01 ata-Optiarc_DVD_RW_AD-7930H -> ../../sr0
    lrwxrwxrwx. 1 root root  9 Jan 11 17:01 ata-ST95005620AS_5YX1K0Q5 -> ../../sda
    lrwxrwxrwx. 1 root root 10 Jan 11 17:01 ata-ST95005620AS_5YX1K0Q5-part1 -> ../../sda1
    lrwxrwxrwx. 1 root root 10 Jan 11 17:01 ata-ST95005620AS_5YX1K0Q5-part2 -> ../../sda2
    ...
    ...
    
  • by-uuid

    $ ls -l /dev/disk/by-uuid
    total 0
    lrwxrwxrwx. 1 root root 10 Jan 11 17:01 xxxxxx -> ../../sda1
    lrwxrwxrwx. 1 root root 10 Jan 11 17:01 xxxxxx -> ../../dm-1
    lrwxrwxrwx. 1 root root 10 Jan 11 17:01 xxxxxx -> ../../dm-0
    lrwxrwxrwx. 1 root root 10 Jan 11 17:01 xxxxxx -> ../../dm-2
    

    Where the xxxxxx would be an actual UUID such as 5ece678c-1234-5678-12e3-88c06ec11111.

  • by-label

    $ ls -l /dev/disk/by-label/
    total 0
    lrwxrwxrwx 1 root root 10 Mar  4 18:21 LABEL1 -> ../../sda4
    lrwxrwxrwx 1 root root 10 Mar  4 18:17 LABEL2 -> ../../sda3
    lrwxrwxrwx 1 root root 10 Mar  4 18:21 LABEL3 -> ../../sda6
    lrwxrwxrwx 1 root root 10 Mar  4 18:42 LABEL4 -> ../../sda7
    lrwxrwxrwx 1 root root 10 Mar  4 18:20 LABEL5 -> ../../sda5
    

    Where LABEL1,LABEL2,… etc are label which shows symbolic links to actual partition (e.g /dev/sda3).

For instance, the command

lsblk -o name,mountpoint,label,size,uuid

outputs:

You can specify plenty of columns in whatever order you like:

Available columns:
       NAME  device name
      KNAME  internal kernel device name
    MAJ:MIN  major:minor device number
     FSTYPE  filesystem type
 MOUNTPOINT  where the device is mounted
      LABEL  filesystem LABEL
       UUID  filesystem UUID
         RO  read-only device
         RM  removable device
      MODEL  device identifier
       SIZE  size of the device
      STATE  state of the device
      OWNER  user name
      GROUP  group name
       MODE  device node permissions
  ALIGNMENT  alignment offset
     MIN-IO  minimum I/O size
     OPT-IO  optimal I/O size
    PHY-SEC  physical sector size
    LOG-SEC  logical sector size
       ROTA  rotational device
      SCHED  I/O scheduler name
    RQ-SIZE  request queue size
       TYPE  device type
   DISC-ALN  discard alignment offset
  DISC-GRAN  discard granularity
   DISC-MAX  discard max bytes
  DISC-ZERO  discard zeroes data

I use also lsblk mentioned above, but I find the following options better suiting:

sudo lsblk -o name,mountpoint,tran,fstype,label,size
Answered By: Eduard Florinescu

Very easy:

lsblk -fp

Description from the man page:

  -f, --fs
          Output info about filesystems.  This option is equivalent to -o NAME,FSTYPE,LABEL,UUID,MOUNTPOINT.  The authoritative information about filesystems and raids is provided by the blkid(8) command.

  -p, --paths
          Print full device paths.

On both of the following distributions I have tested the command:

  • Red Hat Enterprise Linux 8.1 (Ootpa)
  • Ubuntu 18.04.3 LTS (Bionic Beaver)

Result:

I found out how I get the fslabel of the fsroot partition as a regular user. This page helped me to succeed. Was not easy. Many commands only work with sudo, but /etc/mtab and /dev/disk/by-label are readable as regular user.

Here is the bash code:

test=`cat /etc/mtab|grep " / "`
test=${test%% *}
test=${test##*/}
test=`ls -l /dev/disk/by-label/|grep $test`
test=${test%% ->*}
test=${test##* }
