Using a remote file as an argument
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.
