I tried to update Homebrew on time with launchd. My plist file is presented here:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>ms.liu.homebrew.update</string>
<key>UserName</key>
<string>LiuMS</string>
<key>ProcessType</key>
<string>Background</string>
<key>EnvironmentVariables</key>

<string>/usr/local/bin/brew</string>
<string>update</string>

<key>StartCalendarInterval</key>
<dict>

<key>Minute</key>

</dict>
<key>StandardOutPath</key>
<string>/usr/local/logs/ms.liu.homebrew.update.out</string>
<key>StandardErrorPath</key>
<string>/usr/local/logs/ms.liu.homebrew.update.err</string>
</dict>
</plist>
It does work somehow: I can execute launchctl start ms.liu.homebrew.update
manually to update my Homebrew. However, launchd doesn't execute this service periodically: last changes to the file which stdout redirects to is two days ago.
I tried to get info about this service but got nothing:
> launchctl print user/%MyPID%/ms.liu.homebrew.update``
Could not find service "ms.liu.homebrew.update" in domain for uid: %MyPID%
It looks like I haven't successfully loaded my service. How? I used launchctl load
but it seems that it has been deprecated. Man page recommends bootstrap instead:
> launchctl bootstrap user/%MyPID% %Path-to-plist%
> %Path-to-plist%: Service cannot load in requested session
What should I do? How to properly use launchctl bootstrap
and launchctl print
?
