Returned objects from shell commands?

Hello,

what is the idea of the returned objects of shell commands?

Unfortunately, they are printed to the console if not assigned to a
shell variable.

Commands like shell:wc is not returning an java.lang.Long if asked to
return number of lines. It's tricky to compare the string of shell:tac
to anther number with shell syntax.

With kind regards
