Using /w which shows wide format but less detail.

Using /p which pauses output but does not change details.

💡 Hint

Common Mistakes

Using -Directory instead of -File to filter folders.

Using -lt which means less than, opposite of what is needed.

-File filters only files, and -gt means greater than, so files larger than 1MB are listed.

5fill in blank

hard

Fill all three blanks to create a Bash command that finds all '.txt' files and counts them.

PowerShell

find [1] -name [2] | wc [3]

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

A.

B"*.txt"

C-l

D-w

Attempts:

3 left

💡 Hint

Common Mistakes

Using -w with wc which counts words, not lines.

Using directory other than current (.) which changes search location.

Not quoting the '*.txt' pattern causing shell expansion issues.

find . -name "*.txt" finds all text files in current directory and subdirectories. wc -l counts the lines, which equals the number of files found.
