Comparing directories

Comparing directories is useful when two people are working on the same set of files, for example, the chapters of a book. By comparing the directories you can quickly identify which files are different.

To compare two directories, use the dircmp(C) (directory compare) command, as follows:

dircmp directory1 directory2

The output is a list of the differences between the directory listings for directory1 and directory2, for example:

   $ dircmp ./dir1 ./dir2

   					    ./t.appx.s
   					    ./t.prog.s
   					    ./t.scosh.s
   					    ./t.shell.s
