##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)

#launchd Usage

I have a bash script called foo.sh that takes one command line argument, bar. I want it to run every 60 seconds and load at startup.

• an XML plist is Apple Property List
• com.mydomain.foo.plist Name of launchd plist file should be a reverse fqdn, like (this may not be required, but convention)
• com.mydomain.foo.plist lives in $HOME/Library/LaunchAgents and is ran as that user.
• com.mydomain.foo.plist can also live /Library/LaunchDaemons or /Library/LaunchAgents, have requirements, ran as root
• Load plist with launchctl load com.mydomain.foo.plist
• Unload plist with lauchctl unload com.mydomain.foo.plist
