I'm a bit confused on this one. I know bash is POSIX compliant, but I'm not sure about the others. I'll have to review the POSIX standards to make sure I get this right.

Okay, I've got this. Bash and ksh are both POSIX compliant shells, so I'll mark those. I'm not as confident about csh and zsh, so I'll have to guess on those.
