# Usage: bash macports_update_reminder.sh
#
# The idea is that you add this script to your shell profile (e.g. ~/.bash_profile) so that
# you are reminded to update MacPorts after 7 days every time you open a new terminal window.

# This script alerts the user to run an update if it was more than 7 days since the last update
# and prompts the user to run the update.
# The user must successfully run the update through this script for the reminder to be reset so
# the check does not need root privileges or network access. The script uses sudo to run the macports
# update.

# Timestamp file location
TIMESTAMP_FILE="$HOME/.last_macports_update"

# The number of days after which to remind the user to update MacPorts
REMIND_AFTER_DAYS=7
