Its a great convenience. If you have a list of items and you are
interested only in one or two of them, using an array gives you
instant identification of them, like so:-
IFS=$'\x0A' # elements separated by line breaks only
nzb=($(ls /home/g/dnlds/*.nzb))
rm ${nzb[0]} # ditch previous download
pan --no-gui -o /home/g/Films --nzb "${nzb[1]}" # make download
IFS=$'\x20'$'\x09'$'\x0A'$'\x0D' # reset default
Pretty much if I watch a movie, I download one, which minimizes the
amount of HD I must devote to movies. Otherwise they eat up the HD at
a fantastic rate. And its virtually all done with bash internals,
which I think will be more efficient than calling a separate app like
head (though its no big deal either way).
