Didn't think of that at all - I think any of the other solutions posted that
called 'ls' have this problem too.  The only way to do it correctly by maki=
ng
calls to ls seems to be to parse the output of the dired mode (which isn't
hard, but hard to do in one line).

You can also have ls output strings meant for C which are properly escaped =
and
quoted, but I don't know of any way to unescape them without eval (also
possibly causing issues if for some strange reason a #{} sequence is in a
filename):

`ls -Q1 --color=3Dnever *.jpg`.split("\n").collect do |item| eval("#{item}"=
) end

So I guess the pure ruby methods are better.

btw, to make one of these crazy files in bash (this took me a bit of work) =
type
the following line:
touch 'test^v^jing'

where the ^v is typed as control-v

I used to know the answer to that one, before I ate so many preservatives...
