Re: joining array elements

[Wataru Kagawa <wkagawa@xxxxxxxxxxxxxxxxxxxx>]

Hi Peter,

Thank you for the tip.  I would like to place the expansion into a  
variable, however, I am having a trouble.

% usernames=( Bob Sara Tim )
% print -R ${(j:[return]:)~~usernames}
Bob[return]Sara[return]Tim

However,

% foo=$( printf '%s\n' David Matt ${(j:[return]:)~~usernames} )
% echo $foo

I appreciate any suggestions.
