that function will run dmenu_path | dmenu every time, but in the above case $var can be reused multiple dtimes while dmenu_path | dmenu is only run once. in this example it may not matter, but in other cases it can make a difference if running the command has sideeffects or changes the result. 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.
