Determine Default App for File Type from Command Line

By  on  

One quality of life improvement any developer can make for themselves is ensuring different file types open in the app they're most proficient in. If you know me, you know I prefer accomplishing as much as possible from the command line. The duti utility allows users to determine default file type from command line.

The duti utility allows developers to query which app is the default for different file types. You can install duti with brew:

brew install duti

Once you have duti available, you can check on the default app for file type with the following command:

~ duti -x md
Xcode.app
/Applications/Xcode.app
com.apple.dt.Xcode

You can set the default app by using its package:

duti -s com.sublimetext.2 .js all

The duti utility is really great for determining and automating default app management!
