Trailing characters error in a substitution command

Question

Suddenly simple find&replace stopped working in one particular case. I'm selecting the code-block in visual-mode, so the final command looks like:

'<,'>%s/someStuff/stuff/gI

I get the error:

Trailing characters

It's very strange behavior because the same commands worked very well earlier.

Search and replace in VIM results in trailing characters didn't help.

Answer 1

You don't need %, as you already have another range ('<,'>) for your command s. So it must be simply '<,'>s/SomeStuff/stuff/gI.
