> :g/^\s*$/d

I believe I've used a similar 'delete empty lines command' in the past, but it was just:

    :g/^$/d

Can someone explain what the OP's regex is doing differently?

Your version deletes empty lines, but the version you quoted deletes lines that are blank or only have white space.

Edit to be more helpful:

^ is the start of a line

\s is a space character

* means "zero or more of the previous character"

$ is the end of a line

Got it. He specifically said, "Remove all blank lines", so I assumed they were doing the same thing. I should've recognized \s as the space character.

> I should've recognized \s as the space character. … whitespace pattern.
