Installation guide
For complete information about user applications and commands, see
Section 2.3 and Appendix A.
The DIGITAL UNIX system provides three shells: the C shell (csh), the
Bourne shell (sh), and the Korn shell (ksh). For information about how
these shells compare to the ULTRIX equivalent shells, see Section 2.4. For
information about migrating shell scripts, see Section 3.2.
1.2.2 Development Tools
The DIGITAL UNIX development environment is similar to the ULTRIX
development environment. Both the DIGITAL UNIX system and the
ULTRIX system (for RISC users) offer an ANSI C compliant compiler. In
addition to compiling ANSI C programs, the compiler includes a
compilation mode that allows you to compile programs written in
traditional Kernighan and Ritchie (K&R) C.
The programming tools that are available on the DIGITAL UNIX system
are traditional UNIX programming tools and new tools. You can use the
dbx debugger on DIGITAL UNIX systems to find errors in your program.
The system includes the make utility for building your application and the
sccs utility for storing your application’s source files. You can purchase the
DEC FUSE software for use on the DIGITAL UNIX system; DEC FUSE
includes a computer-aided software engineering (CASE) environment for
developing software.
Using the DIGITAL UNIX programming software, you can write programs
that communicate over a network, that provide windowing user interfaces,
that are portable to multiple systems, and that are adaptable to multiple
locales.
Once your application is fully developed, you can use the setld utility to
package the application as a kit for installation on DIGITAL UNIX
systems. For more information about the DIGITAL UNIX development
environment, see Chapter 6. For information on building installable
software kits, see the Programming Support Tools manual.
1.2.3 File Systems
The DIGITAL UNIX system supports the following file systems:
• Advanced File System (AdvFS)
• UNIX File System (UFS)
• Network File System (NFS)
