No, I've done no testing at all, other than manually unzipping the few zipped ports I use ever since tar(1) could unzip, and unzipping the odd file here and there from usenet or email. I wouldn't say I've encountered a lot of zipped files, but tar(1) has worked for all of them. > 3) Some ports pass custom flags to unzip command, there would blow up > when replaced with tar, too. It'd be possible to depend on the unzip port for older FreeBSD versions and if there are custom flags, but I guess that's probably a lot of work just to avoid a dependency on a small port. Depending on it when there's no reason to depend on it just bugs me though. -- Skip
