You need to force globbing. Try this:
lsd() { local -a pat; pat=(${^*:-*}'(/N)'); ls -d ${~pat} }
(How to do it without a temporary variable?)

} You need to force globbing. Try this:
}
} lsd() { local -a pat; pat=(${^*:-*}'(/N)'); ls -d ${~pat} }
}
} (How to do it without a temporary variable?)
By simply doing it without a temporary variable!
lsd() { ls -d ${^~*:-*}(/) }
If you throw in the (N) like Christian did, "lsd notadirectory" will give
you "./" which may or may not be what you want.
If you want to be able to handle other "ls" options ("lsd -l m*") then
you'll need temporaries to capture the options and patterns separately.
But handling all the possible options of "ls" is a large task all by
itself ...

Meh, I tried to do something like ${~${^...}}} and failed. ;)
