In both zsh and bash the "command" shell builtin (and its cousin builtin) are helpers for bypassing shell functions or aliases.

Thanks for pointing this out and sorry for not responding sooner. I admit I haven't used command and I should have looked it up first, because of course that changes things - it seems strange to want to call the shell only to tell the shell to not use a builtin or function. As a side note, interestingly, it looks like command is slightly different in the two shells: bash says "Runs command with arguments ignoring any shell function named command. Only shell builtin commands or commands found by searching the PATH are executed." while in zsh: "The simple command argument is taken as an external command instead of a function or builtin and is executed. If the POSIX_BUILTINS option is set, builtins will also be executed but certain special properties of them are suppressed." - another argument for avoiding The problem of "the" default shell.

nysus: What is task? If it's something like Taskwarrior (where apparently task list is a valid command), then my suggestion above is actually wrong because no shell is needed, and you should be using something like system('/usr/bin/task','list') instead. See also my node Calling External Commands More Safely.
