- 〈italics〉
Italic type enclosed in angle brackets indicates
parameters that you will supply. This same convention also applies
to the actual path names of directories. Note that the path names
given in angle brackets depend on the file system structure. See
the Graphics Administration Guide for details.
- .

. The vertical ellipsis indicates that irrelevant
parts of a program example or illustration have been omitted.
- computer font
This constant-width, computerish-looking font indicates
verbatim entries that you will make on the command line or as program
text including routine names, parameters, and file or directory
names.
Environment Variable Conventions
In this document, you will be given examples that set various
environment variables using the Korn shell.
An environment variable can be set using anyone of four shell
environments: Bourne shell, Korn shell, POSIX shell, and C shell.
The Bourne, Korn, and POSIX shells set environment variables in
the same manner; however, the C shell uses a different set of commands.
Here is an example of setting an environment variable using either
the Bourne, Korn, or POSIX shell:
〈environment_variable〉=TRUE
export 〈environment_variable〉 |
To unset this environment variable, execute the following
command:
unset 〈environment_variable〉 |
If you prefer using the C shell, here is an example of how
you would set an environment variable:
setenv 〈environment_variable〉 TRUE |
To unset this environment variable, execute the following
command:
unset 〈environment_variable〉 |
Setting PATH and MANPATH
In this document, you will be given examples that refer to
various executables and on-line reference pages. To conveniently
access these executables and online reference pages, your PATH and MANPATH environment variables
must include the appropriate Starbase and graphics directories.
The following commands will add the necessary directories (the actual
path name of the directory given in angle brackets depends on the
file system structure; see the Graphics Administration
Guide for details.):
PATH=$PATH:〈starbase〉/bin:〈common〉/bin
MANPATH=$MANPATH:〈starbase〉/share/man
export PATH MANPATH |
