"set -o" and "alias" are not in the least FreeBSD-exclusive. Nor do we have a unique implementation with "export VAR=value". These three features don't differ with respect to portability. To repeat: * They aren't part of the "original" Bourne shell (which was itself a moving target). * They were introduced with the Korn shell. * Later they were specified for the POSIX shell. * Every POSIX shell supports them. Whatever way you want to argue, if you want to stay coherent you have to treat these three features (and a bunch more) the same. And, considering the subject, I'd like to point out that FreeBSD's /bin/sh is not a Bourne shell clone but a POSIX shell. > Extending that argument to either not take advantage of features > unique to FreeBSD (silly and wasteful) or to doing everything FreeBSD'ish > just because we can (teaches a bad lesson) goes too far in either > direction for my taste. I think that's a bizarrely schizophrenic position, but anyway it isn't applicable to the actual shell features discussed above. -- Christian "naddy" Weisgerber naddy@mips.rhein-neckar.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
