Not really; as was noted, the expression is bash-specific, and lots of
non-Linux Unices don't have bash. So while it's more verbose, every
/bin/sh on pretty much any sane system will be able to run
`echo "$1" | sed -e 's/\\.[^.]*//'`
(Provided, of course, that you can read the sed expression, which is
s/ \\. [^.]* / /
search-and-replace ".", then any number of not-dots, with nothing.)
