Vim - search and replace results

Question

Is it possible to perform the results of search and replace to make sure that your code has not been made any unwanted changes to offset the performance of search and replacement of the entire file?

Vim displays a status message:

"*X* substitutions on *Y* lines"

and I'm curious if there is a key or command to go through each of these substitutions and perform a quick check to make sure you don't shoot yourself in the foot with unexpected line matches. New for Vim; sorry if this is an obvious or irrelevant question! Thanks for the help:)

Answer 1

From http://vim.wikia.com/wiki/Search_and_replace ,

:%s/foo/bar/gc
    Change each 'foo' to 'bar', but ask for confirmation first.

Answer 2

, Google, Vim SO:

• :substitute:

  :help :s
  

• , [flags]:

  :[range]s[ubstitute]/{pattern}/{string}/[flags] [count]
      [...
      skipped lines
      ...]
      See |:s_flags| for [flags].
  

• <C-]> :s_flags.

• Hooooo...
