It also says, for example: expr1 + expr2 Addition of decimal integer-valued arguments. So, under your interpretation, "expr 010" would print 8, but "expr 010 + 0" would print 10? That doesn't sound right to me. > Neither that nor the info documentation says anything about a base for > the integer constants.

Even if you're right that POSIX allows "expr 08" to fail (which I doubt), GNU expr would still disagree with all the other implementations out there. I don't think the incompatibility hassles would be worth it. There are lots of places where POSIX is inconsistent: sometimes it requires that 010 be treated as 8, sometimes not. It's a mess, but fixing it would require changing POSIX, not an easy task and one that I'm not sure is worth it. Plus, how many old scripts would you break? _______________________________________________ Bug-coreutils mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/bug-coreutils
