💡 Hint

Common Mistakes

Using -s only shows total size, not all directories.

Using -a shows all files, which is more than needed.

The -h option shows sizes in a human-readable format like KB, MB.

💡 Hint

Common Mistakes

Using -a lists all files and directories, too much detail.

Using -c adds a grand total, not just the directory total.

The -s option summarizes the total size of the directory.

3fill in blank

💡 Hint

Common Mistakes

Using 'var' without slash looks in current directory, which may not exist.

Using '~/var' looks in home directory, not /var.

The absolute path /var is needed to correctly specify the directory.

4fill in blank

hard

Fill both blanks to show disk usage of /home directory in human-readable format and summarize only total size.

Linux CLI

du [1] [2] /home

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

A-h

B-s

C-a

D-c

💡 Hint

Common Mistakes

Using -a shows all files, not just summary.

Using -c adds a grand total which is not needed here.

Use -h for human-readable sizes and -s to summarize total size.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps each subdirectory in /tmp to its size in human-readable format, only if size is greater than 100K.

Linux CLI

sizes = [1]: subprocess.check_output(['du', '-h', '-s', f'/tmp/[2]']).decode().split()[0] for [3] in os.listdir('/tmp') if int(subprocess.check_output(['du', '-s', f'/tmp/[2]']).decode().split()[0]) > 100}

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

💡 Hint

Common Mistakes

Using different variable names causes errors.

Using 'item' instead of 'd' breaks the comprehension.

Use the same variable d for key and value construction and iteration.
