I tried this and wound up deleting it the same way I created it:
rm `echo -e l\\\010\\\010\\\010`
I don't have much shell-fu, so this could probably be done a better
way, but it did the trick. I'd recommend a more general fix for the
problem, though - maybe something like this:
#!/usr/bin/perl
opendir F, '.';
for $old (readdir(F)) {
$new = $old;
$new =~ s/([\x00-\x1f\x7f-\xff])/hex(ord($1))/e;
rename $old, $new if $old != $new;
}
The shell is a fiddly place to be messing around with unprintables -
if you use an 8-bit clean language that implements rename() or
unlink(), your results will be more predictable.
