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).

    Labels? What's a label? Are you talking about ext2 labels? Those have nothing to do with partition tables per se. Commented Mar 30, 2011 at 6:33
  • Hi @Chris Jester-Young, thanks for your comment! I have tried to clarify above - yes, I believe it is ext2 labels I'm talking about... Cheers! Commented Mar 30, 2011 at 6:37

    Partitions don't have labels, but file systems do. You need a combination of tools to do that. The blkid tool can tell you label of a known partition. But to find the partition you would have to loop over the output of fdisk. Commented Jun 2, 2011 at 3:13

    @Keith, as a side note, I'd like to add that the new GPT partitions have a name field which is similar to filesystem labels. Commented Jun 3, 2014 at 16:26

with lsblk

For instance, the command

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

outputs:

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.

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

/dev/disk

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

Example

$ ls -l /dev/disk

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

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.

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:

$ lsblk -fp

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:\n\n"

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%% ->*}
