  • Requires wdiff. Prints the word-by-word diff with the old version highlighted in red, and the new in green. Change the colors by altering 41m and 42m. 45m is more of a magenta and may be easier to read.

  • I put this in a shell script called "svndiff", as it provides a handy decorated "svn diff" output that is colored (which you can't see here) and paged. The -r is required so less doesn't mangle the color codes. Show Sample Output

  • It can be hard to spot differences in reformatted files, because of all the diff noise created by word wrapped lines. This command removes all the noise and performs a word-by-word diff. To ignore empty lines, add -B to the diff command. Also, if this is something you do often, you might want to check out the wdiff(1) program.
