It's fine, although anything inside the ticks does in fact get executed, eg
which apachectl
expands to /usr/local/bin/apachectl (not running apache, don't remember 
the freebsd location offhand but you get the point)

so then the literal text '/usr/local/bin/apachectl' replaces the command 
inside the ticks to become:

more /usr/local/bin/apachectl

So yep, it's doing what you want, the way you wanted to...use something 
similar fairly often myself, although note that the 'current' standard 
for executing commands is now $(cmd), eg

more $(which apachectl)
