How can I search and replace recursively in a directory in Vim?

Question

I found out about Vim\'s substitute command...

:%s/replaceme/replacement/gi

And vimgrep...

:vimgrep  /findme/gj  project/**/*.r         


        

Answer 1

To answer the original question of combining vimgrep and substitute:

:vimgrep /pattern/ ./**/files              # results go to quickfix list
:set autowrite                             # auto-save when changing buffers
:silent! cdo %s/replaceme/replacement/gic  # cdo draws filenames from quickfix list
:set noautowrite

Leave out the c of gic if you don't want to confirm each replacement (in which case you could also use find and sed as suggested by @LaurenceGonsalves).
