By the time we're done, you'll be the master mechanic, ready to ace the exam. Let's tackle the first hurdle, 

You can delete all the time lines using the following command:

:g/^\d\{1,2\}:\d\{2\}/d

Command Breakdown

• :: Starts command-line mode.

• g: Stands for "global." It applies the subsequent command (d) to every line that matches the preceding pattern.

• /^\d\{1,2\}:\d\{2\}/: This is the pattern (regex) to match the time lines.

  • ^: Matches the start of the line.

  • \d\{1,2\}: Matches one or two digits (for the minute/hour part, e.g., '0' or '10'). \d is the escape for a digit, and \{1,2\} is the quantifier.

  • :: Matches the literal colon.

  • \d\{2\}: Matches exactly two digits (for the seconds part, e.g., '00' or '07').

• d: The command to execute on the matched lines, which is delete.
