% sed --version GNU sed version 4.1.4 Copyright (C) 2003 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE, to the extent permitted by law. It's true that older and non-Gnu sed implementations do not have this option, but unless you're going to restrict yourself to POSIX-compliant subsets of all commands you use in scripting, you're really committing yourself to the Gnu implementations. These implementations are riddled with very significant extensions and improvements, many of which I'm not willing to forgo, knowing as I do that my scripts will always be running in a Gnu / Linux environment. > -dnh Randall Schulz -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
