tkdiff is a graphical diff viewer based on the Tk framework.[http://sourceforge.net/projects/tkdiff/ tkdiff home page] It is capable of inter-operating with source-control systems like CVS and Subversion to show the differences between the local copy and the repository version. Such a line-by-line comparison is often considered to be good software engineering practice before committing code changes.
Tkdiff highlight specific differences within a line shared by both files, rather than simply indicating that the whole line differs.
Example usage
tkdiff
— to compare the two files
andtkdiff
— to compare the local version of the given file to the most recent version in the CVS/Subversion repository
tkdiff can also compare two older revisions of a file, etc.[http://linux.math.tifr.res.in/manuals/man/tkdiff.html tkdiff manual page]
