There are several other differenced of "select" from "read". For example
zsh's "select" will accept a maximum of 256 bytes of input, doesn't do
any special handling of multibyte characters, won't allow a line to be
continued with a backslash, etc. In bash,
select foo in a b c; do loopbody; done
seems to be equivalent to
while read "?$PS3"; do
case $REPLY in (1) foo=a;; (2) foo=b;; (3) foo=c;; (*) foo="";; esac
loopbody
done
Zsh also prints an extra newline after the select is done.
