Try this: eval whatevercommand \''$file'\' As for doing the same without eval, it can be done, too, by setting the sh_word_split option and tweaking, or simply with this: options=("-x") (($#)) && options=("-y" "$1") CMD $options[1] $options[2] foo If "foo" comes from a parameter, just use that parameter instead of "foo". I haven't tested the solution, so it may need some refinement, but it should do.
