in reply to Re^3: what's the difference between "$@" and ${1+"$@"}
in thread what's the difference between "$@" and ${1+"$@"}
And I finally found a web page that discusses this, with some good background detail.
http://www.in-ulm.de/~mascheck/various/bourne_args
As an interesting side note, I wonder if anyone knows how to give this string (${1+"$@"}) to Google's search engine. As is, it doesn't work. I tried single-quoting it, and it still doesn't work.
Cadphile...
