POSIX requires shells to support case x in (x), but older bourne shells do not support this newer syntax. That is probably why you were not taught it; if I understand correctly, it was invented in ksh, then standardized by POSIX, which is why bash now has it. At any rate, several platforms, including Solaris' /bin/sh, still do not parse ( in case patterns even today, so it is certainly not portable if you don't have access to a POSIX shell. > P.S.

Reply-To: bug-bash@gnu.org, [EMAIL PROTECTED] Indeed, this points out another (probably related) parsing problem in bash 3.1: Buggy (here-doc delimiter treated as $() closer): $ echo $( > cat << ')' > hello > ) hello Expected: $ echo $( > cat << ')' > hello > ) > ) hello -- Eric Blake _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
