Practice - 5 Tasks

1fill in blank

easy

Complete the command to list all block devices on your system.

Linux CLI

lsblk [1]

Drag options to blanks, or click blank then click option'

A-m

B-l

C-a

D-f

💡 Hint

Common Mistakes

Using -a shows all devices including empty ones, but not in list format.

Using -f shows filesystem info, not the device list.

Using -m shows permissions, not the device list.

The lsblk -l command lists all block devices in a list format, showing partitions and devices clearly.

Complete the command to start fdisk on the device /dev/sda.

Linux CLI

sudo fdisk [1]

Drag options to blanks, or click blank then click option'

A/dev/sda

B/dev/sdb

C/dev/sdc

D/dev/sdd

💡 Hint

Common Mistakes

Using /dev/sdb or other devices when the main disk is /dev/sda.

Forgetting to use sudo for administrative privileges.

To modify partitions on the main disk, you use sudo fdisk /dev/sda.

hard

Fix the error in the command to print detailed info about partitions using lsblk.

Linux CLI

lsblk [1]

Drag options to blanks, or click blank then click option'

A-o NAME,SIZE,TYPE,MOUNTPOINT

B-p

C-d

D-r

💡 Hint

Common Mistakes

Using -d shows only devices, no partitions.

Using -p shows full device paths but not detailed columns.

Using -r shows raw output, not formatted columns.

The -o option lets you specify columns to show. Using -o NAME,SIZE,TYPE,MOUNTPOINT shows detailed partition info.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps partition names to their sizes using lsblk output.

Linux CLI

sizes = { [1]: [2] for part in partitions }

Drag options to blanks, or click blank then click option'

Apart

Bpart.size

Cpart.name

Dpart.mountpoint

Attempts:

💡 Hint

Common Mistakes

Using mountpoint instead of size for values.

Using the same variable for key and value.

This comprehension creates a dictionary where keys are partition names (part.name) and values are their sizes (part.size).

5fill in blank

hard

Fill all three blanks to filter partitions larger than 1G and create a dictionary of their names and sizes.

Linux CLI

large_parts = { [1]: [2] for p in partitions if [3] > 1_000_000_000 }

Drag options to blanks, or click blank then click option'

Ap.name

Bp.size

Dp.mountpoint

Attempts:

3 left

💡 Hint

Common Mistakes

Using mountpoint instead of size for filtering.

Using inconsistent variable names.

This comprehension filters partitions where size is greater than 1GB (1,000,000,000 bytes) and maps their names to sizes.
