💡 Hint

Common Mistakes

Choosing words that mean the opposite of saving time, like 'wastes'.

The word 'saves' correctly completes the sentence to explain that automation helps save time and effort.

💡 Hint

Common Mistakes

Using '-d' which checks for directories instead of files.

The '-f' option checks if 'backup.txt' is a regular file, which is needed before copying it.

Fix the error in the script that lists all running processes containing 'ssh'.

Bash Scripting

ps aux | grep [1]

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

B'ssh' | grep -v grep

C"ssh"

Dssh

💡 Hint

Common Mistakes

Not excluding the grep process, so it appears in the output.

Using 'grep -v grep' removes the grep process itself from the results, showing only actual 'ssh' processes.

4fill in blank

hard

Fill both blanks to create a loop that prints numbers 1 to 5.

Bash Scripting

for i in [1]; do
  echo [2]
done

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

A1 2 3 4 5

Bi

C$i

Dseq 5

Attempts:

💡 Hint

Common Mistakes

Using 'i' instead of '$i' to print the variable value.

The loop iterates over the list '1 2 3 4 5' and prints each number using '$i'.

5fill in blank

hard

Fill all three blanks to create a script that counts files in a directory and prints the count if more than 3.

Bash Scripting

count=$(ls [1] | wc -l)
if [[ [2] [3] 3 ]]; then
  echo "There are $count files."
fi

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

A/tmp

B$count

C-gt

D-lt

💡 Hint

Common Mistakes

Using the wrong comparison operator like '-lt' instead of '-gt'.

The script counts files in /tmp, then checks if count is greater than 3 to print the message.
