If I want to get a brief usage message for a bash builtin, I can use
help <builtin> at a command prompt, e.g.
$ help export export: export [-fn] [name[=value] ...] or export -p Set export attribute for shell variables. Marks each NAME for automatic export to the environment of subsequently executed commands. If VALUE is supplied, assign VALUE before exporting. Options: -f refer to shell functions -n remove the export property from each NAME -p display a list of all exported variables and functions An argument of `--' disables further option processing. Exit Status: Returns success unless an invalid option is given or NAME is invalid.
How can I do this in zsh? I've tried
% export --help zsh: bad option: -e
% help export zsh: command not found: help
Also the word "help" isn't anywhere in
