var=$(dmenu_path | dmenu); first executes dmenu_path, and if that fails it runs dmenu. the output is saved and stored in $var. $var may be reused many times. temp_func would execute dmenu_path every time it is called. (and now that i look at it, it doesn't even do what is expected here, namely take the string that dmenu_path dmenu print, and run that as a command.) greetings, martin. -- cooperative communication with sTeam - caudium, pike, roxen and unix offering: programming, training and administration - anywhere in the world -- pike programmer travelling in china community.gotpike.org unix system- iaeste.(tuwien.ac|or).at open-steam.org administrator caudium.org is.schon.org Martin Bähr http://www.iaeste.or.at/~mbaehr/ ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
