do :%s/^./\U&/ then :%s/_./\U&/g

the first will uppercase the first letter of every line, the second will uppercase the first letter after each underscore in all lines.

Combining the two search/replace Rob suggested:


will search for either the first char in a line or the first char following an _.


  • \| specifies 'or'
  • g will change all occurrences in a line
  • c will ask for confirmation
