To ask south to print the file south!/schedule/january using the lp command, you would type:

uux 'south!lp' '/schedule/january'

where /schedule/january is the name of the file on south to be printed. In general, if no site is specified on the arguments for the remote command, uux assumes the command is on the site running the command. You must specify full pathnames for files in uux commands. As a general rule, enclose all arguments to uux in single quotation marks to prevent the shell from interpreting them.
