For what it's worth I have two scripts I've created.
# ll /usr/local/sbin/scs-check-for-*
# less /usr/local/sbin/scs-check-for-ports-updates-cron.sh
/usr/sbin/portsnap cron update && /usr/sbin/pkg version -vIL=
# less /usr/local/sbin/scs-check-for-ports-updates.sh
/usr/sbin/portsnap fetch update && /usr/sbin/pkg version -vIL=
read -r -p "Press Enter key to continue..." key
and then I have a symlink set to call the cron version on a daily basis.
lrwxr-xr-x 1 root wheel 51B Jan 14 2013 /etc/periodic/daily/610.scs-check-for-ports-updates-cron.sh -> /usr/local/sbin/scs-check-for-ports-updates-cron.sh
The use of the cron command vs a simple fetch means portsnap waits a random time between 0 and 3600 seconds (1 hour) before fetching. This helps to prevent everyone hitting the port tree servers at exactly the same time (usually we admins cron on the hour).
usage: portsnap [options] command ... [path]
-d workdir -- Store working files in workdir
-f conffile -- Read configuration options from conffile
-I -- Update INDEX only. (update command only)
-k KEY -- Trust an RSA key with SHA256 hash of KEY
-l descfile -- Merge the specified local describes file into the INDEX.
-p portsdir -- Location of uncompressed ports tree
-s server -- Server from which to fetch updates.
path -- Extract only parts of the tree starting with the given
string. (extract command only)
fetch -- Fetch a compressed snapshot of the ports tree,
or update an existing snapshot.
cron -- Sleep rand(3600) seconds, and then fetch updates.
extract -- Extract snapshot of ports tree, replacing existing
files and directories.
update -- Update ports tree to match current snapshot, replacing
files and directories which have changed.
Because this script is cron daily in my "[HOSTNAME] daily run output" email I get every morning I see something like....
amavisd-new-2.8.0_2,1 < needs updating (index has 2.9.1,1)
syslog-ng-22.214.171.124 < needs updating (index has 3.5.6_3)
