How to list disks, partitions and filesystems in Linux? [duplicate]
In Windows, if you type LIST DISK using DiskPart in a command prompt it lists all physical storage devices, plus their size, format, etc. What is the equivalent of this in Linux?

There are many tools for that, for example fdisk -l or parted -l , but probably the most handy is lsblk (aka list block devices):
Example
$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 238.5G 0 disk ├─sda1 8:1 0 200M 0 part /boot/efi ├─sda2 8:2 0 500M 0 part /boot └─sda3 8:3 0 237.8G 0 part ├─fedora-root 253:0 0 50G 0 lvm / ├─fedora-swap 253:1 0 2G 0 lvm [SWAP] └─fedora-home 253:2 0 185.9G 0 lvm It has many additional options, for example to show filesystems, labels, etc. As always man lsblk is your friend.
@Dor it is worth explaining what additional options do, if you are recommending their use. -f or —fs shows the information about filesystems, such as format, crypto, raid member, etc. It is somewhat slower than the default though.
You’ll like this : you can do sudo lsblk —scsi and this shows the disk types including name(sda,sdb. ), scsi addr, type,vendor, model, rev, .. it’s easy to find which is which when you want to physically locate the disk.
Another way to quickly see the filesystems is the command df. On my machine (Finnish localization) it shows like this:
ptakala@athlon:/mnt$ df Tiedostojärjestelmä 1K-lohkot Käyt Vapaana Käy% Liitospiste /dev/root 38317204 19601752 16762352 54% / devtmpfs 4063816 0 4063816 0% /dev tmpfs 4097592 81988 4015604 3% /dev/shm tmpfs 4097592 10120 4087472 1% /run tmpfs 5120 8 5112 1% /run/lock tmpfs 4097592 0 4097592 0% /sys/fs/cgroup /dev/sda9 535267140 287403688 220666804 57% /work /dev/sda7 288239836 201635356 71956016 74% /home tmpfs 819520 4 819516 1% /run/user/113 tmpfs 819520 8 819512 1% /run/user/1000 /dev/sda1 39070048 37083304 1986744 95% /mnt/sda1 /dev/sda10 22662140 14032580 8629560 62% /mnt/sda10 /dev/sda5 29280176 20578032 8702144 71% /mnt/sda5 It won’t show the file system type, but usually that is non-essential, and you see by one eyedrop everything needed.

This detailed guide will give you enough information to start using Emacs, and enough extra to make you want more.
There are several ways to list all the hard drives present in a system through Linux command lines.
Keep in mind a hard drive could be physically connected, virtually connected or even emulated (for example: when you use storage devices such as EMC, Sun or IBM).
Here are some different commands which can list the hard drives, keep in mind there are others but these are probably the most commonly used and easy to get the job done.
Listing Hard Drives in Linux
Please note that some of these commands are actually disk partitioning tools and listing disk partition is one of their features.
Let’s see what commands you can use to show disk info in Linux.
1. df
The df command in Linux is probably one of the most commonly used. It lists the actual “disk space usage” and it can give you information about what hard disks (or current disk space) is being used in the entire system.
The most common way to use it is with the -h argument which means “human readable” (because we are not machines, right?):
[email protected]:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 7.8G 0 7.8G 0% /dev tmpfs 1.6G 3.5M 1.6G 1% /run /dev/sda2 468G 204G 242G 46% / tmpfs 7.8G 109M 7.7G 2% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup /dev/loop0 7.5M 7.5M 0 100% /snap/canonical-livepatch/54 /dev/loop1 90M 90M 0 100% /snap/core/6034 /dev/loop2 5.0M 5.0M 0 100% /snap/canonical-livepatch/50 /dev/loop4 90M 90M 0 100% /snap/core/6130 /dev/loop3 4.8M 4.8M 0 100% /snap/canonical-livepatch/49 /dev/loop5 89M 89M 0 100% /snap/core/5897 /dev/sda1 511M 6.1M 505M 2% /boot/efi tmpfs 1.6G 16K 1.6G 1% /run/user/121 tmpfs 1.6G 44K 1.6G 1% /run/user/1000As you can see, the first column is the current logic name (or the name you can find it within your system), the second column is how big is each of them, the third column is how much is currently used (in bytes), the fourth column is how much is currently available in each for usage (in bytes), the fifth column is how much is used (in %) and the sixth and last column is where is it physically mounted in your Linux system.
2. fdisk
fdisk is another common option among sysops. It currently lists the different partitions (which is related to hard drives as a hard drive can be divided into several partitions) in your system.
[email protected]:~$ fdisk -l Disk /dev/loop0: 7.5 MiB, 7811072 bytes, 15256 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop1: 89.5 MiB, 93818880 bytes, 183240 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop2: 4.9 MiB, 5148672 bytes, 10056 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop3: 4.7 MiB, 4919296 bytes, 9608 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop4: 89.5 MiB, 93835264 bytes, 183272 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop5: 88.2 MiB, 92483584 bytes, 180632 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/sda: 477 GiB, 512110190592 bytes, 1000215216 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 129F4EE6-2A54-4639-BFCA-2CC09DFC8566 Device Start End Sectors Size Type /dev/sda1 2048 1050623 1048576 512M EFI System /dev/sda2 1050624 1000214527 999163904 476.4G Linux filesystem This will return the entire amount of space (in GB or MB), the entire amount of bytes and the entire amount of sectors per each partition and as a summary, it also gives you the start and end sectors, the amount of disk space (in Bytes) and the type of partition.
Tip: Usually a SATA disk is labelled with sd.
3. lsblk
This one is a little more sophisticated but gets the job done as it lists all block devices. It will give you a very simple list of all devices:
[email protected]:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 7.5M 1 loop /snap/canonical-livepatch/54 loop1 7:1 0 89.5M 1 loop /snap/core/6034 loop2 7:2 0 4.9M 1 loop /snap/canonical-livepatch/50 loop3 7:3 0 4.7M 1 loop /snap/canonical-livepatch/49 loop4 7:4 0 89.5M 1 loop /snap/core/6130 loop5 7:5 0 88.2M 1 loop /snap/core/5897 sda 8:0 0 477G 0 disk ├─sda1 8:1 0 512M 0 part /boot/efi └─sda2 8:2 0 476.4G 0 part /It is probably more visual than the others as it even shows the partitions per each disk in a visual way (like the sda in the example above). It also gives information about the total size per each partition and disk and the physical location for each. This is very commonly used when you need to mount things to be used (like a USB stick or similar) so you can know where is it in order to proceed to mount it.
4. cfdisk
cfdisk is probably the most advanced one in GUI (Graphical User Interface), as it is absolutely visual and interactive. It allows at first to list all disks/partitions in your system but it also allows you to manage them by selecting them and then applying actions such as “Delete”, “Resize”, “Type” (to change partition Type) and “Write” changes done to partitions.
It also gives you very friendly information about each partition and disk as it gives you where does each partition cylinders start and ends, amount of sectors used by each one and the full size of each one with its type. It won’t give you for example how much is used or free to use.
5. parted
This one is similar to previous ones mentioned, it lists all partitions and allows to manage them. Its main difference is that it also informs you the brand and model of your hard disks and even the type of connectivity used in it (scsi, sata, etc) and total disk size.
[email protected]:~$ sudo parted -l Model: ATA LITEON CV1-8B512 (scsi) Disk /dev/sda: 512GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 538MB 537MB fat32 EFI System Partition boot, esp6. sfdisk
This is very similar to fdisk, however sfdisk allows you to see both physical and logical volumes and also gives you a “summary” of the actual physical volumes’ partitions with the cylinders (start and end), sectors, size and type.
Probably the “s” is for “super”, as it is a fdisk with super powers:
[email protected]:~$ sudo sfdisk -l Disk /dev/loop0: 88.2 MiB, 92483584 bytes, 180632 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop1: 4.7 MiB, 4919296 bytes, 9608 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop2: 4.9 MiB, 5148672 bytes, 10056 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop3: 89.5 MiB, 93818880 bytes, 183240 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop4: 7.5 MiB, 7811072 bytes, 15256 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop5: 89.5 MiB, 93835264 bytes, 183272 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/sda: 477 GiB, 512110190592 bytes, 1000215216 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 129F4EE6-2A54-4639-BFCA-2CC09DFC8566 Device Start End Sectors Size Type /dev/sda1 2048 1050623 1048576 512M EFI System /dev/sda2 1050624 1000214527 999163904 476.4G Linux filesystemThese commands should allow you to at least see what logical volumes, partitions and hard drives you have in your system and make use of this information for whatever reason you need it, being this just to know more or manipulate any of these.
Most of these commands also give you managing capabilities to modify and manipulate partitions at your will, so make sure to use them with responsibility.
