That's a bit drastic and pretty much something you'ld never actually
want to do in normal usage. However, for completeness' sake:
# pkg_delete -af
will remove all installed ports. After doing that there should be
hardly anything left under /usr/local -- most of what's left would be
config files in /usr/local/etc.
The -f is probably not needed. I've done this rarely enough to not
recall, but -a should sort everything in the right order so dependencies
are uninstalled in order.
The advice to use portmaster is good.
A typical session to maintain all your ports goes something like this:
# portsnap fetch update (Gets the latest contents for
/usr/ports)
# less /usr/ports/UPDATING (Check for any special
instructions affecting any
ports you have installed.
Assuming nothing out of the
ordinary is required (and it
usually isn't), then...)
# pkg_version -vIL= (see what needs updating)
# portmaster -a (update everything out of date)
portmaster can show ports that can be updated:
portmaster -L --index-only
Or, more concisely:
portmaster -L --index-only | egrep '(ew|ort) version|total install'
There's a short overview of port upgrading procedures and reasoning
