Useful vim tricks

• Chain :wn after another ex command in vim with | to "move on to the next file" (and just repeat the same thing), e.g. to do a replace all and move on:

  echo "hello world" > a.txt
  echo "hello? world?" > b.txt
  echo "helloooo world" > c.txt
  vim {a,b,c}.txt

  ⇣

  :%s/o/a/g | wn

  You might combine this with grep to find the files with the matching string:

  vim $(grep -r "o" | cut -d ":" -f 1 | sort | uniq)
