Simple periodic maintenance script
Because my macs are not always awake at the scheduled times for the periodic cron system maintenance tasks, I've started to run them from a script every week or so.
The simple script I use is shown below:
#!/bin/bash set -v # Running the daily,weekly and monthly periodic scripts sudo periodic daily && sudo periodic weekly && sudo periodic monthly # Updating pre-binding sudo update_prebinding -root / -force # Repair disk permissions sudo diskutil repairPermissions /
