====== Show Hard Disk Size Linux ======
<color darkorange>Sep 2023</color>
\\ 
==== Overview ====

----

Just a quick note on how to show the entire disk size in Linux, rather than just the partitions.
\\ 
\\ 
    fdisk -l | grep '^Disk'
\\ 
==== Example ====
<file>
fdisk -l | grep '^Disk'

Disk /dev/sda: 465.76 GiB, 500107862016 bytes, 976773168 sectors
Disk model: Samsung SSD 850 
Disklabel type: dos
Disk identifier: 0x1f26beb5
Disk /dev/mapper/almalinux-root: 70 GiB, 75161927680 bytes, 146800640 sectors
Disk /dev/mapper/almalinux-swap: 7.79 GiB, 8367636480 bytes, 16343040 sectors
Disk /dev/mapper/almalinux-home: 386.96 GiB, 415500337152 bytes, 811524096 sectors
</file>
\\ 
The first line in the output shows the hard disk size:
\\ 
\\ 
Disk /dev/sda: <color #ed1c24>465.76 GiB</color>, 500107862016 bytes, 976773168 sectors
\\ 
\\ 
The remaining three lines are the partitions within that disk:
\\ 
\\ 
Disk /dev/mapper/almalinux-root: <color #ed1c24>70 GiB</color>, 75161927680 bytes, 146800640 sectors
Disk /dev/mapper/almalinux-swap: 7.79 GiB, 8367636480 bytes, 16343040 sectors
Disk /dev/mapper/almalinux-home: <color #ed1c24>386.96 GiB</color>, 415500337152 bytes, 811524096 sectors.
\\ 
\\ 
The three partitions are <color #ed1c24>70GB + 7.79Gb + 70GB = 464.75GB</color> which is the disk size (all bar 1MB)
