Interactive search/replace regex in Vim?

I know the regex for doing a global replace,

%s/old/new/g

How do you go about doing an interactive search-replace in Vim?

Neovim now has a feature inccommand which allows you to preview the substitution:

inccommand has two options:

  • set inccommand=split previews substitutions in a split pane
  • set inccommand=nosplit previews substitution in the active buffer

enter image description here

Add the flag c (in the vim command prompt):

:%s/old/new/gc

will give you a yes/no prompt at each occurrence of 'old'.

"old" is highlighted in the text; at the bottom of the window it says "replace with new (y/n/a/q/l/^E/^y)?)"

Vim's built-in help offers useful info on the options available once substitution with confirmation has been selected. Use:

:h :s

Then scroll to section on confirm options. Screenshot below:

Text that says "[C] Confirm each substitution. [...] CTRL-Y to scroll the screen down"

For instance, to substitute this and all remaining matches, use a.

If your replacement text needs to change for each matched occurrence (i.e. not simply choosing Yes/No to apply a singular replacement) you can use a Vim plugin I made called interactive-replace.

If you just want to count the number of occurrences of 'abc' then you can do %s/abc//gn. This doesn't replace anything but just reports the number of occurrences of 'abc'.

Mark Biek pointed out using:

%s/old/new/gc

for a global search replace with confirmation for each substitution. But, I also enjoy interactively verifying that the old text will match correctly. I first do a search with a regex, then I reuse that pattern:

/old.pattern.to.match
%s//replacement/gc

The s// will use the last search pattern.

I think you're looking for c, eg s/abc/123/gc, this will cause VIM to confirm the replacements. See :help :substitute for more information.

I usually use the find/substitute/next/repeat command :-)

/old<CR>3snew<ESC>n.n.n.n.n.n.n.

That's find "old", substitute 3 characters for "new", find next, repeat substitute, and so on.

It's a pain for massive substitutions but it lets you selectively ignore some occurrences of old (by just pressing n again to find the next one instead of . to repeat a substitution).
