# This cron script contains several (commented out) examples.  You may use
# them as is, by uncommenting them, or modify them to suit your needs.  Read
# tmpwatch(8) for more information on tmpwatch parameters.

### Variables ###

TMPWATCH="/usr/sbin/tmpwatch"
#PORTAGE_TMPDIR="$(portageq envvar PORTAGE_TMPDIR)/portage"
#PORTAGE_LOGDIR="$(portageq envvar PORT_LOGDIR)"
#DISTDIR="$(portageq distdir)"

### EXAMPLES ###

# NOTE: if you have noatime in /etc/fstab for any partitions you plan on
# running tmpwatch on, you should obviously change any of the examples that
# use atime (-u|--atime).  Those that don't specify anything, default to 
# atime.

# NOTE2: the time value is in HOURS!

# Delete everything in /tmp that haven't been accessed in a week (>=168 hrs).
#
# if [[ -d /tmp ]]; then
#   ${TMPWATCH} --atime 168 /tmp
# fi

# Delete everything in PORTAGE_TMPDIR that hasn't been modified in 2 weeks.
#
# if [[ -d ${PORTAGE_TMPDIR:-/var/tmp/portage} && -z $(/usr/bin/pgrep emerge) ]]; then
#   ${TMPWATCH} --mtime --all 336 ${PORTAGE_TMPDIR:-/var/tmp/portage}
# fi

# Delete everything in DISTDIR that hasn't been accessed in 6 months (going
# by 30 day months)
#
# if [[ -d ${DISTDIR:-/usr/portage/distfiles} ]]; then
#   ${TMPWATCH} --atime --fuser 4320 ${DISTDIR:-/usr/portage/distfiles}
# fi

# Delete everything in PORTAGE_LOGDIR that hasn't been accessed in 4 weeks
#
# if [[ -d ${PORTAGE_LOGDIR:-/var/log/portage} ]]; then
#   ${TMPWATCH} --atime 772 ${PORTAGE_LOGDIR:-/var/log/portage}
# fi
