System settings that aren’t in System Settings
It's now a habit to save all my changes in system and app preferences in a script.<p>First I do a<p><pre><code>    defaults read > 1
</code></pre>
Then I change the setting in the app or System Settings, then back on the commandline, I do<p><pre><code>    defaults read > 2
    diff 1 2
</code></pre>
The change gets copied to a preferences.sh file with a whole bunch of statements like:<p><pre><code>    defaults write com.apple.ical "Show Week Numbers" -bool true
</code></pre>
Afterwards, I don't care where the setting is. I just set it in my preferences.sh file, and if I update any of it, I run that file.
