ooh boy, I think the answer is, "you don't" - why do you need to?

Un use case could be in the %post section, if you want to run a
postinstall of a (bad) commercial package and you want to put in a
shell a sigalarm (something like this) for not to wait forever if
something go wrong. I have done this in the past IIRC. But it is only
an example, for probably a rare use case.

I was able to do that using triggerin -- packagename.

Thanks for helping.

Assuming you are in one of the scripted sections such as %build,
%install, etc. or an rpm pre/post type scriptlet, you'd do it the same
way you would do it in a regular shell script.

I can't help but wonder what a good valid usage case of this is however,
and would generally discourage any attempt to do that.
