The variations of the text in these lists is tremendous and I'm sorry for wasting your time as you would have to inspect quite a few lists to know what commands to use, and I didn't post them. It just took lots of research, and I solved it.
I appreciate your nudge in the right direction, though! Thanks!
I would like to do this:

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
