1fill in blank

easy

Bash Scripting

💡 Hint

Common Mistakes

Using quotes around the list makes it a single string, not a list.

Using parentheses or brackets is not valid for list iteration in bash.

In bash, to loop over a list of words, you write them separated by spaces without quotes or parentheses.

2fill in blank

medium

Complete the code to loop over the list and print each item in uppercase.

Bash Scripting

for item in apple banana cherry; do
  [1] "$item"
done

💡 Hint

Common Mistakes

Using 'echo' alone does not change case.

Using 'cut' does not change letter case.

Using 'tr' with input redirection converts the text to uppercase.

3fill in blank

hard

Fix the error in the loop to correctly iterate over the list and print each element.

Bash Scripting

for i in [1]; do
  echo "$i"
done

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

A"apple banana cherry"

Bapple banana cherry

Capple,banana,cherry

D(apple banana cherry)

💡 Hint

Common Mistakes

Using commas breaks the list into one string.

Using quotes makes the entire list one item.

The list should be space-separated words without quotes or commas for bash to iterate correctly.

4fill in blank

hard

Fill both blanks to create a loop that prints only fruits with names longer than 5 letters.

Bash Scripting

for fruit in apple banana cherry date; do
  if [[ ${#fruit} [1] 5 ]]; then
    echo $[2]
  fi
done

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

B"$fruit"

C<

💡 Hint

Common Mistakes

Using '<' would print fruits with names shorter than 5 letters.

Printing 'echo' instead of the variable name.

Use '>' to check if length is greater than 5, and print the fruit variable.

5fill in blank

hard

Fill all three blanks to create a loop that prints fruits in uppercase only if their name length is less than 7.

Bash Scripting

for fruit in apple banana cherry date; do
  if [[ ${#fruit} [1] 7 ]]; then
    [2] "$fruit" | [3] '[:lower:]' '[:upper:]'
  fi
done

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

💡 Hint

Common Mistakes

Using '>' instead of '<' for the length check.

Using 'cut' or other commands instead of 'tr' for case conversion.

Use '<' to check length less than 7, 'echo' to output the fruit, and 'tr' to convert to uppercase.
