unix - How to schedule a script which executes daily? [OSX] -


i have python script want run daily @ let's 9 am. if system not on @ time, script should run computer gets turned on again.

i'm looking anacron.

how can achieve this? cron job doesn't fulfill purpose.

create launch daemon file, set ownership root:wheel , permissions 644, , place in /library/launchdaemons. @ minimum, file should contain this:

<?xml version="1.0" encoding="utf-8"?> <!doctype plist public "-//apple computer//dtd plist 1.0//en" "http://www.apple.com/dtds/propertylist-1.0.dtd"> <plist version="1.0"> <dict>     <key>label</key>     <string>local.maintenance</string>     <key>programarguments</key>     <array>         <string>/path/to/your/script</string>     </array>     <key>startcalendarinterval</key>     <dict>         <key>hour</key>         <integer>9</integer>         <key>minute</key>         <integer>0</integer>     </dict> </dict> </plist>

note although missed run of daemon made @ next opportunity, it'll "coalesce" multiple missed runs. example, if computer off 5 days, daemon run once when starts up.
