In Vim, to join lines, use the ‘J’ command. This merges the line where the cursor is with the line below it. For multiple lines, prefix ‘J’ with a count, like ‘3J’ to join three lines.
To split lines, there’s no built-in command. However, you can replace spaces with newline characters using substitute command ‘:s’. To split a line at a space, position your cursor on the line and type ‘:s/ /\\r/’. The ‘\\r’ represents a newline character in Vim’s regex engine. If you want to split at specific places, replace the space between slashes with the desired character or pattern.
