Unadorned `echo` may or may not support a particular option, dependent on if it is a shell (which one?) built in or an external command. See the start & the bottom of GNU echo invocation; mix in korn-shell (sic) for extra fun. Variable expansion(substitution) is also shell dependent ... generates error `${PATH/...}: Bad substitution` in FreeBSD 6 /bin/sh (ash); generates error `Missing }` in tcsh 6.15; at least works in zsh 4 & bash 3* here.
