The default program used is "diff -Npru". To select a different program, use the -p option. The program will be passed the names of two directories to compare. To pass additional options to the program, use the -o option. These will be passed before the names of the directories to compare. When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent.tprograms diff -NpruN(RIRRR5R9(RRR9R5((R%textdiffdsRKtpRJtscomparison program to runtoR1s!pass option to comparison programtrR-trevisiontItincludes)include names matching the given patternstXtexcludes)exclude names matching the given patternsshg extdiff [OPT]...
