  The comp.unix.shell newsgroup is a good place.

Suppose I need to encode a list of filenames in a variable and each
filename may contain spaces, what is good way to encode such a list so
that the resulting variable is readily compose-able and decodeable? In
particular, I'd like to avoid the use of (unescaped) separators which
might themselves be used in the filename.

   Either separate them with newlines, or (non-POSIX) use an array.


## Array
files+=( "$nextfile" )
