Use the following commands to view disk space, partitions, and layouts:

df -hT        # View disk usage with filesystem types 
lsblk         # List block devices 
fdisk -lu     # Detailed partition table (MBR) 
sfdisk -l     # Alternative partition listing

🔁 Swap Partition Management

✅ Enable a Swap Partition

1. Create the Swap Partition using parted:

parted > unit s              # Use sectors for units 
> print free          # Show available space 
> mkpart primary swap-partition <start-sector>s 100%

2. Initialize the Swap Area:

swapon /dev/sdaX

3. Enable the Swap:

swapon /dev/sdaX

4. Verify Swap Status:

swapon --show

5. Make Swap Permanent:

• Get the UUID of the swap partition:

blkid

• Edit /etc/fstab and add:

`UUID=<swap-partition-uuid> none swap sw 0 0`

---

🚫 Disable a Swap Partition

1. Turn Off the Swap:

swapoff /dev/sdX

2. Verify:

swapon --show

3. Delete the Partition:

parted
> print free
> rm <partition-number>`

---

⬆️ Extend a Partition

1. Resize with parted:

parted 
> print free 
> resizepart <partition-number> 100%

2. Resize the filesystem inside the partition

resize2fs /dev/sdX

3. Verify

df -h
