The following reply was made to PR bin/169500; it has been noted by GNATS. From: Mark Linimon <linimon@lonesome.com> To: bug-followup@FreeBSD.org Cc: Subject: Re: bin/169500: expr(1) improperly requires forward slash to be escaped Date: Wed, 27 Jun 2012 21:24:40 -0500 ----- Forwarded message from Robert Bonomi <bonomi@mail.r-bonomi.com> ----- Date: Wed, 27 Jun 2012 20:44:25 -0500 (CDT) From: Robert Bonomi <bonomi@mail.r-bonomi.com> To: linimon@freebsd.org Subject: Re: bin/169500: expr(1) improperly requires forward slash to be escaped FWIW, the putative 'bug' is documented on the manpage for expr. There is nothing wrong with the 1003 regex handling. It is operator/operaand recognition in expr. Using something that is parsable as an operator _as_ an operand. is a syntax error for the ':' operator -- EXPRESSLY so stated on the manpage. Using _any_ token that is parsable as an 'operator' (arithmetic, or logical) as an operand for ':' will result in the same non-bug error The 'Examples' section of the manpage documents a work-around -- actually using '/' as the example. Shoulc be closable -- with the traditional IBMism -- "it's not a bug, it's a _feature_, and =documented= as such." *BIG* grin. ----- End forwarded message -----
