ok say the map is at www.foobar.com; at the shell, get into the wfa dir. do a wget www.foobar.com/mymap.zip
if its on ftp, do ftp via commandline (ftp ftp.foobar.com, cd to the dir, binary, get mymap.zip)
if it lands in your home dir then just move (mv) it.
unzip the map via commandline. (unzip mymap.zip)
kill the q3 process (either attatch back to the console or kill the process id). might as well take this time to edit (pico) the maplist.cfg
restart it.
cmds like pico, ftp, wget, mv, kill, ps, unzip are about all you are gonna need to know. use google.
