probably rolling its eyes as it did so...
short version:
if your text file has one word per line, try this:
netselect -vv `cat my-settings-file`
long version:
if you 'store' the output of a command in a variable,
you get all the tabs, spaces and newlines verbatim.
when you use that as an argument to a command,
*nix scrunches all whitespace into single space
characters, so all the command will 'see' is the
individual words.
for fancier stuff, try
generate-some-list-however-you-like | xargs cmd -options
man xargs for the full poop.
