Print packages whose files have not been accessed in over 6 months (or some arbitrary time).

This list is meant to be a best-guess indication of packages which you seldom use and could probably do without.

Usage: pacruft [options]
    -y, --years  <years>
    -m, --months <months>
    -d, --days   <days>
    -h, --help

$ pacruft
bar
bmpanel
chkrootkit
gmrun
gtk1-engines
gtk-rezlooks-engine
gtk-smooth-engine
libvisual-plugins
qingy-theme-arch
rpmextract
uudeview

A 6 month threshold is the default if no options are passed. One month is represented simplistically as exactly 30 days.

Multiple options will sum, so pacruft -m 6 -d 15 would show packages not accessed in the past 195 days ([ 30 * 6 ] + 15).

If any options are passed, the 6 month default is disabled, so pacruft -d 15 would only represent a 15 day threshold.

Some packages own files unreadable by an unprivileged user. These files are ignored and the package is evaluated as if the unreadable file(s) didn't exist. Additionally, a package with no readable files will never appear as old.

This script only performs reads, so it's probably safe to run as root to get the most accurate listing.
