How do you insert a newline after every 80 characters in vim? -


i have long line of characters in vim. i'd insert newline after 80 characters. how do that?

:%s/.\{80}/&\r/g
  • %: process entire file
  • s: substitute
  • .: matches character
  • {80}: matches every 80 occurrences of previous character (in case, character)
  • &: match result
  • \r: newline character
  • g: perform replacement globally
