dircmp command

On Unix-like operating systems, the dircmp command compares two directories, and reports differences in their contents.


The dircmp command examines DIRECTORY1 and DIRECTORY2 and generates information about the contents of the directories. Listings of files that are unique to each directory are generated for all the options. If no option is entered, a list is output indicating whether the file names common to both directories have the same contents.


dircmp [-d] [-s] [-w n] DIRECTORY1 DIRECTORY2


-d Compare the contents of files with the same name in both DIRECTORY1 and DIRECTORY2 output a list telling what must be changed in the two files to bring them into agreement. The list format is described in diff.
-s Does not tell you about the files that are the same.
-w n Change the width of the output line to n characters. The default width is 72.


dircmp dir1 dir2

Compares the directory dir1 with the directory dir2. Below is an example of the output you may receive when running this command:
