archives get unpacked, but the relevant prt-get.conf and ports tree are those
on the parent filesystem. Therefore it is not necessary for <dir> to contain
its own copy of the ports tree (unless 'runscripts yes' is desired, as
explained above). However, if <dir>/etc/pkgadd.conf exists and is different
from /etc/pkgadd.conf, then install or update commands might behave
unexpectedly. In order to preserve the \fBpkgadd.conf(5)\fP settings from the
explained above). But each \fBpkgmk(8)\fP process will take place on the parent
filesystem, inspecting \fIthe parent filesystem\fP's environment for
information about installed ports and available shared libraries. The
\fBpkgmk(8)\fP process might therefore draw the wrong conclusions about what
functionality should be enabled for an installation to <dir>. If the parent
filesystem is more richly populated than <dir>, with respect to installed
packages, then the built package might exhibit breakage when \fBpkgadd\fP
unpacks it into <dir>.
When setting --install-root=<dir>, install or update commands might behave
unexpectedly if <dir>/etc/pkgadd.conf exists and is different from
/etc/pkgadd.conf . In order to preserve the \fBpkgadd.conf(5)\fP settings from
host system, append the option --aargs='-c /etc/pkgadd.conf' to your \fBprt\-get
install\fP command, or just copy the desired directives into
<dir>/etc/pkgadd.conf .

.B prt\-get isinst $(prt\-get quickdep i3) | awk '/not installed/ { print $2 }' | xargs prt\-get depinst \-\-softdeps \-\-test
(inspired by a troubleshooting session with hestia) Assemble a set of install
targets needed to build the i3 window manager; sort the list, respecting both
hard and soft dependencies; then print how the installation would proceed. The
awk filter in the middle is needed to prevent the command from failing with the
error message "already installed".
.TP
.B prt\-get printf \(dq%p\et%u\en\(dq | grep myrepo | cut -f 2
Print the upstream URL for each port in the collection \(dqmyrepo\(dq,
perhaps as the first step in keeping your personal overlay up to date.
.TP
.B prt\-get printf \(dq%M\et%n\en\(dq | grep ^Tim | wc -l
Count how many ports our most-overworked core team member claims
responsibility for.
.B prt\-get printf \(dq%M\et%n\en\(dq | grep -c -i ^unmaintained
Count how many ports are marked unmaintained (and hence at risk of being dropped
from the repos by the time you next run 'ports -u').
