Hi. I've read the handbook and the porter's handbook, and have
looked at /usr/ports/Mk/bsd.port.*, but still haven't found an
answer to my question.
Is it possible, with a simple command or script, to update all
of the ports I have installed at once? I mean, I want to make
sure that all of the ports that I use are the latest version,
but I don't want to install ports that I don't use.
The short answer is: No, there isn't a way, and even if there was, you
wouldn't want to do it. Remember, "newer isn't always better".
If anyone has a good way of doing this automatically, please let
me know. (I'm using -STABLE, if that matters.)
"pkg_version -v" will help you figure out what's newer.
"pkg_version -c" will generate some scripting stuff that will help you
do some of the upgrading (but remember to RTFM to see all the
caveats).
Look at the archives for the -ports list to see many messages
discussing this problem. :-p
Hope this helps,
Bruce.
