3.1.1 Setting the C Shell filec and PATH Environment Variables
The DIGITAL UNIX system C shell contains most features of the ULTRIX
C shell. One difference between the two shells is that the ULTRIX C shell
includes file name completion by default. On DIGITAL UNIX systems, you
must set the filec environment variable to enable file name completion.
To set the filec environment variable, enter the following command:
% set filec
You can include this command in your .login file to have the filec
variable set each time you log in or in your .cshrc file to set the variable
in all subshells. Once you set the variable, you can press the Escape key to
request that the shell complete file names on the command line.
On DIGITAL UNIX systems, the default search path for the csh shell is
.:/usr/bin. On ULTRIX systems, the default search path is
.:/usr/bin:/bin. On the DIGITAL UNIX system, the /usr/ucb
directory is a link to the /usr/bin directory. For information about the
DIGITAL UNIX C shell, see csh
(1).
3.1.2 Setting the Bourne Shell PATH Environment Variable
On DIGITAL UNIX systems, the default search path for the sh shell is
:/usr/bin. On ULTRIX systems, the default search path is
:/usr/bin:/bin. On the DIGITAL UNIX system, the /bin directory is a
link to /usr/bin, so there is no need to add /bin to your path. However,
there are commands in /usr/sbin that you might want to access. To
enable the shell to access commands in /usr/sbin, add that directory to
the sh search path. The following example shows the line to include in your
.profile file to add the /bin directory to the default search path:
PATH=:/usr/bin:/usr/sbin; export PATH
Including this command in your .profile file adds the /usr/sbin
directory to the default sh search path each time you log in to the system.
3.1.3 Setting International Environment Variables
The DIGITAL UNIX system has environment variables that control some
aspects of how you interact with programs. The environment variables
control how international programs display messages, accept input, and
display data. International programs use DIGITAL UNIX features to
display messages in your native language, collate strings as you expect,
format monetary and numeric data as you expect, and so on. The following
sections describe how to set these environment variables.
