💡 Hint

Common Mistakes

Using single > which overwrites the log file.

Using pipe or input redirection symbols incorrectly.

Use >> to append the warning message to the log file without overwriting existing content.

💡 Hint

Common Mistakes

Using > which overwrites the log file.

Using an incorrect log level or missing it.

The function logs messages with the level INFO and appends them to /var/log/app.log.

hard

Fill all three blanks to create a log entry with dynamic level and message.

  level=[1]
  message=[2]
  echo "$(date) $level: $message" [3] /var/log/custom.log
}

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

💡 Hint

Common Mistakes

Using > which overwrites the log file.

Not quoting the parameters properly.

The function assigns the first argument to level, the second to message, and appends the formatted log entry to /var/log/custom.log.
