(duti
duti is a command-line utility capable of setting default applications for
various document types on macOS, using Apple's
Uniform Type
Identifiers
(UTI). A UTI is a unique string describing the format of a file's content. For
instance, a Microsoft Word document has a UTI of com.microsoft.word.doc. Using
duti, the user can change which application acts as the default handler for a
given UTI.
Compiling
autoreconf -i
./configure
make
sudo make install
Usage
duti can read settings from four different sources:
-
standard input
-
a settings file
-
an XML property list (plist)
-
command-line arguments.
A settings line, as read in cases 1 and 2, consists of an application's bundle
ID, a UTI, and a string describing what role the application handles for the
given UTI. The process is similar when duti processes a plist. If the path
given to duti on the command-line is a directory, duti will apply settings
from all valid settings files in that directory, excluding files whose names
begin with . (single dot).
duti can also print out the default application information for a given
extension (-x). This feature is based on public domain source code posted
by Keith Alperin on the heliumfoot.com blog.
See the man page for additional usage details.
Examples
-
Set Safari as the default handler for HTML documents:
duti -s com.apple.Safari public.html all -
Set TextEdit as the default handler for Word documents:
echo 'com.apple.TextEdit com.microsoft.word.doc all' | duti -
Set Finder as the default handler for ftp:// URLs:
duti -s com.apple.Finder ftp -
Get default application information for .jpg files:
duti -x jpg # Output Preview /Applications/Preview.app com.apple.Preview
