:help change.txt
mentions 2- or 3- letter :substitute commands, such as :sg
, :sgn
and so on. I am guessing that these :s[xx]
correspond to flags, but am not sure how to use them.
For example, I would think that :%sg/foo/bar
would substitute all matches of foo
, including multiple occurences on the same line. However, that commands gives me an error --- "trailing characters".
What is the appropriate syntax for :s[x[x]]
?
