💡 Hint

Common Mistakes

Using '-a' shows hidden files but not details.

Using '-h' changes size format but needs '-l' to show details.

Using '-R' lists directories recursively, not detailed info.

The '-l' option lists files with detailed info like permissions, size, and date.

💡 Hint

Common Mistakes

Using '-a' shows hidden files but not size format.

Using '-R' lists directories recursively, unrelated to size format.

Using '-l' again is redundant.

The '-h' option shows sizes in human-readable format when combined with '-l'.

C-R

D-h

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-a' instead of '-R' lists hidden files but not recursively.

Using '-h' changes size format but does not list recursively.

Use '-l' for details and '-R' to list directories recursively.

5fill in blank

hard

Fill all three blanks to list all files with details and human-readable sizes.

Linux CLI

ls [1] [2] [3]

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

D-R

Attempts:

3 left

💡 Hint

Common Mistakes

Omitting '-a' hides hidden files.

Omitting '-h' shows sizes in bytes only.

Using '-R' is not needed here.

Use '-a' to show all files, '-l' for details, and '-h' for human-readable sizes.
