💡 Hint

Common Mistakes

Using '-a' which shows all filesystems but not human-readable sizes.

Using '-l' which limits output to local filesystems.

Using '-t' which filters by filesystem type.

The '-h' option makes the output human-readable by showing sizes in KB, MB, or GB.

💡 Hint

Common Mistakes

Using '-T' which shows filesystem type but not human-readable sizes.

Using '-i' which shows inode information instead of disk space.

Using '-x' which excludes filesystem types.

The '-h' option shows the sizes in a human-readable format for the specified directory '/' (root).

💡 Hint

Common Mistakes

Using '-hT' which shows both human-readable sizes and filesystem type.

Using '-t' which filters by filesystem type instead of showing it.

Using '-i' which shows inode info, not filesystem type.

The '-T' option shows the filesystem type in the output.

4fill in blank

💡 Hint

Common Mistakes

Using '-T' which shows filesystem type but does not exclude anything.

Using 'tmpfs' as an option instead of a value for '-x'.

Use '-h' for human-readable sizes and '-x tmpfs' to exclude tmpfs filesystems.

5fill in blank

hard

Fill all three blanks to create a dictionary of mount points and their used space in human-readable form.

Linux CLI

df -h | awk '{{print $[1], $[2]' | while read [3] used; do echo "$used on $[3]"; done

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

💡 Hint

Common Mistakes

Mixing up column numbers for mount point and used space.

Using wrong variable names in the while loop.

Column 6 is the mount point, column 3 is used space, and 'mount' is the variable to read mount points.
