Tal com s' espera, un nom apropiat per a un programa com aquest seria & quot; diffquot;. Per descomptat dit programa es troba instal· lat sobre la majoria de sistemes basats en & Linux; i s' usa exactament per a aquest propòsit. Els desenvolupadors usen diff tot sovint, com a una eina de línia d' ordres, per a mostrar diferències entre versions d' un fitxer de codi font. De tota manera, l' ús de diff no es troba limitat a mostrar les diferències, es pot usar sobre molts altres tipus de fitxer basats en text.
As would be expected, an appropriate name for such a program would be & quot; diffquot;. As it happens, the program diff is installed on most & Linux; -based systems and is used for exactly this purpose. Developers often use diff, as a command line tool, to show differences between versions of a source code file. However, the use of diff is not limited to showing differences in code source files, it can be used on many text-based file types.
