I would assume that this works the same as other uses of * and @; if you quote them, * expands to a single Word, while @ expands to a Word for each logical element (so that any spaces in each element are preserved). Similar to how if your argv is 'foo' 'bar none', "$*" gives the single Word 'foo bar none' and "$@" gives { 'foo', 'bar none' }.
IOW this looks like the doc maybe should mention this and fails to do so. -- Matthew "Try to bring it back in one piece this time." -- Q (MI6) _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
