Tkdiff

tkdiff is a graphical diff viewer based on the Tk framework.^[1] 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 uses colors to suggest differences between files and within shared lines.

Tkdiff highlight specific differences within a line shared by both files, rather than simply indicating that the whole line differs.

Example usage

• tkdiff <file1> <file2> — to compare the two files <file1> and <file2>
• tkdiff <file> — 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.^[2]
