* About duti
duti is a command-line utility capable of setting default applications for
various document types on Mac OS X, using Apple's Uniform Type Identifiers. 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
./configure
make
sudo make install
* Usage
duti can read settings from four different sources: 1) standard input;
2) a settings file; 3) a Mac OS X XML property list (plist); 4) 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 '.'.
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.
