The -L option exists in the system's kill command (/bin/kill) but not in zsh's builtin kill command (which you get when you type a bare 'kill'). That is fine because the -L command is a Linux extension to the standard, as documented in both kill(1) and kill(1p) (the latter from the manpages-posix package). So, if you want the -L option, call the system's kill command, not the zsh builtin one. For example: % =kill -L % /bin/kill -L Bottom line: everything works as expected/documented. Cheers, Daniel P.S. The reason for having a builtin kill command is to make things like `kill %2` possible (= killing a job by job number).
