[seqfan] editing in the OEIS wiki

[N. J. A. Sloane]

I am not yet used to editing wiki pages.  Does anyone know how
to do simple "ed"-type edits?

Like  g/bad/s//good/g  ?

Or "dot", meaning "repeat the previous substitution" ?

It would be a giant step backwards if these aren't available!

I would also like to know how to make the same change across
a whole set of pages.  For example, suppose I need to change
"intger" in every page where it appears to "integer" ?

Can it be that the wikimedia software is so primitive
that it doesn't have these commands?

At present the whole OEIS is in one flat file, so it is
trivial to make global edits.  If I want to edit a bunch of files,
I write a little shell program.  In unix, everything is easy.

But in wikimedia, what does one do?
