DECwindows interfaces: OSF/Motif and XUI. The OSF/Motif interface is
almost identical to the DIGITAL UNIX system interface, because the
ULTRIX and UWS implementation is based on OSF/Motif Version 1.2.2.
The ULTRIX and UWS XUI interface is based on the DIGITAL developed
graphical user interface.
2.2 Differences in the DIGITAL UNIX Directory Structure
The directory structure on your DIGITAL UNIX system is different from
the directory structure on an ULTRIX system. Figure 2–1 shows most of
the directories in the root (/) file system.

As the figure shows, the directory structure on DIGITAL UNIX is identical
to the ULTRIX directory structure in many ways. (This figure does not
show the complete directory structure; for example, the /opt, /dev, and
/mnt directories, which are typically not used by general users, are omitted.
See also Section 4.8.1.) The following list describes important differences:
1 Some commands that are in /bin on an ULTRIX system are in the
/usr/bin or /usr/sbin directory on a DIGITAL UNIX system. This
change should not affect you because your PATH environment variable
causes the DIGITAL UNIX system to search the appropriate
directories for commands. As a start, you can use the same definition
for the PATH environment variable as you used on the ULTRIX system.
However, you should remove /bin from your path definition and add
/usr/bin and /usr/sbin.
If you need to determine the location of a particular command that is
not in your path, you can use the whereis command, which looks for
commands in a set of standard locations. If a given command file is in
more than one directory, whereis reports all locations of the command.
