dircmp - Compares two directories
dircmp [-d] [-s] directory1 directory2
The dircmp command reads directory1 and directory2, compares
their contents, and writes the results to standard
output.
Interfaces documented on this reference page conform to
industry standards as follows:
dircmp: XCU5.0
Refer to the standards(5) reference page for more information
about industry standards and associated tags.
Displays for each common file name the differing contents
of the two files, if any. The display format is the same
as that of the diff command. Does not list the names of
identical files.
The path name of a directory to be compared.
First, dircmp compares the file names in each directory.
When the same file name appears in both, dircmp compares
the contents of the two files.
In the output, dircmp lists the files unique to each
directory. It then lists the files with identical names
but different contents. If entered without a option,
dircmp also lists files that have both identical names and
identical contents.
[Tru64 UNIX] In many cases, diff -r, rather than dircmp,
is preferred. The dircmp command is marked LEGACY. The
diff -r command should be used instead.
To summarize the differences between the files in two
directories, enter: dircmp proj.ver1 proj.ver2
This displays a summary of the differences between
the directories proj.ver1 and proj.ver2. The summary
lists separately the files found only in one
directory or the other, and those found in both.
If the file is found in both directories, the file
is listed. If the files are identical, dircmp displays
identical; otherwise, dircmp displays different.
To show the details of the differences
between files, enter: dircmp -d -s proj.ver1
proj.ver2
The -s option suppresses information about identical
files. The -d option displays a diff listing
for each of the differing files found in both
directories.
