vim interactive mode AKA confirmation mode

In Vim, you can enter an interactive mode to replace blank lines one by one using “confirmation mode” in the :substitute command. Here’s how:

Command:

:g/^\s*$/c

Explanation:

• :g/^\s*$/c

• g → Applies the command to all matching lines.

• /^\s*$/ → Matches blank lines (including those with spaces or tabs).

• c → Asks for confirmation before replacing each match.

Interactive Mode:

After running the command, Vim will prompt you for each blank line with options like:

replace with:

Then, you can:

• Type your new content and press Enter to replace the blank line.

• Press n to skip that occurrence.

• Press q to quit replacing.

• Press a to replace all occurrences without further confirmation.
