Nerd Tip of the Month: Mac OS X opendiff command (MergeFiles)

Submitted by Benjamin Melançon on November 6, 2006 - 1:15am

Mac OSX's graphical enhancement of the unix diff command, opendiff (part of the optional free add-on developer tools) can be accessed through terminal like so:

Ebony-697:~/Web Sites Data/LinkLocus/Power2Exchange/css ben$ opendiff style_old.css style_new.css

(You can also grab the files through a graphical interface through [volume]/Developer/Applications/Utilities/FileMerge)

Key, poorly documented commands:

Command up-arrow and command down-arrow to go from one difference to the next.
Command left-arrow to choose the left-column version and command right-arrow to choose the right-column version.

It's very nice.
